When GM introduced the completely redesigned fourth-generation 2019 Silverado and 2019 Sierra, we liked the new styling direction. The fresh fascias did well to complement each brand’s respective styling language, and definitely helped differentiate the new trucks from the previous model years. However, there was one tiny detail that left us scratching our heads – the antennas.
We already expressed our beef with the presence of the large, old-school radio antenna on the passenger-side of the trucks. That’s not what we’re here to discuss today. Instead, we’re here to talk about the “fin” on the roof.
For some reason, GM decided to leave the “shark fin” antenna in the same spot as the previous model year, specifically right above the windshield on the driver’s side of the roof. While not a major design feature, the antenna’s placement makes for an oddly asymmetrical roofline, and with all those new design elements in the fascia, it makes the whole thing unnecessarily messy.

Granted, we understand the need for a fin-style antenna, what with GPS, satellite radio and all the other modern features expected of a modern light-duty pickup. In fact, we like the fin and its aesthetics in general. In other words, the fin is not the problem.
The problem is its placement: why not place it in the middle of the roof, in an equidistant fashion between the passenger and driver’s sides? Or how about in the back, closer to the end of the cab? It certainly wouldn’t interfere with any potential roof rack or roof rails, if that’s at all a concern.

The odd placement also extends to the new 2020 Silverado HD and 2020 Sierra HD. And based on spy shots, the asymmetrical placement will also extend to the all-new 2021 GM SUV lineup – the Chevrolet Tahoe and Suburban, GMC Yukon and Yukon XL, as well as the Cadillac Escalade and Escalade ESV.
2021 Tahoe prototype has the same asymmetrical fin location as the new Silverado and Sierra
Our guess is it has something to do with the existing electrical architecture of both trucks. After all, GM has placed the Silverado/Sierra antenna on the driver’s side roof in practically the same spot since the 2007 model year of the trucks, so perhaps it remains there in the name of saving on costs associated with the wiring.

Comments
I’ve been wondering about this myself. Any actual explanation as to why the fun isn’t centered and toward the rear of the cab?
The most logical conclusion is cost cutting for wiring going into the OnStar stuff into the mirror.
Or maybe it’s easier to build them because the front position is the same for all cabs… but would be different mounting at the rear.
My guess is cost cutting was supported by the rationalization that the current cab forward location presents a lower risk of damage when loading campers or pipe, ladders, (etc…) on cargo racks. In the case of cab over campers the location also offers better reception.
It’s a cost cutting deal guys, plain and simple. The way it is now, they just smack it on every truck no matter the cab in the same location and use the same amount of wiring on every single truck. Moving it to the back and center would require different mounting hardware per cab and different / more amount of wiring. It had nothing to do with campers or trailers or sunroofs or whatever. This is an inch-long protrusion… it’s minimal.
It’s unfortunate that GM’s most profitable products are treated like bargain basement crapshoots.
A GM exec (Reuss?) used the phrase “the devil is in the details” when introducing the last-gen K2 trucks. Not sure how that can be said with a straight face when such blatant items as antennas are made to ease production instead of making a better product.
The fact that Ford and Toyota do this as well shouldn’t matter. GM should lead not follow.
The bean counters have been at work again. They never stop, always looking to save a fraction of a cent.
Just think how much money they save putting it in the same place.
It does work well but the most efficient place to put it would be the center of the roof.
This, exactly! It’s clearly a carefully thought out placement. I’m sure the designers would have preferred it to be symmetrical, too, but that would have been form over function.
I have no problem with the fin position. I currently own a 2018 Silverado. I have always purchased gm vehicle and will continue buying them my dad owned gm vehicles my wife has a Cadillac srx. This is nip picking and finally I have had great service and realibility owning gm vehicles.
It’s a truck, who really cares. My 2014 has the fin over the driver’s side windshield. As long as it works I’m good.
Maybe it’s easier to install by the line worker who can actually reach this location…
You guys aren’t satisfied unless your finding something to complain about. I’ll bet you don’t complain about the cameras on cell phones being off to one side instead of in the middle. This wasn’t even worth an article. Give me break.
Yet another indication bean counters are running GM. I simply could not buy anything made by this company or the greedy UAW Rats….
Why are you on a GM site then?
I clicked the link like everyone else.
I’m staring at a new Tundra with the antenna on the right side of the vehicle at the front and a quick google search shows F-150 is also placed asymmetrically on the right side as well. I would assume that since the middle of the roof is full of existing controls for sunroofs, Onstar, Home Link etc there likely isn’t enough room to jam in the extra wiring. And as already noted positioning at the front is easier for differing cab sizes.
Chances are this is an ergonomic issue at the assembly plants (which is why you see common placement across several manufacturers). It’s easier for someone standing line-side to install and make the electrical connection from outside the vehicle rather than having to climb in to make the connection.
The placement may be due to accessories i.e cab lights sunroof etc. Might be one of the only places that does not interfere.
To be honest, it looks better where they have it. In the middle at the front would just look odd. At the back would also seem out of place.
It would look much better at the back and centered. They’re just too cheap and lazy to do it.
All of these “problems” whether production line or whatever else have viable, simple solutions. Heck they are engineering a vehicle from scratch so there is no reason to not be able to do something this blatantly simple.
Let’s remember they make $20 billion a quarter with these truck products for crying out loud! Billion with a B! Think about that for a minute.
Ergo issue during assembly and will not interfere with the clearance lights on hd trucks
If the little fin bothers you. Paint it your body color like mine is. It all but dissapeares.
Quit complaining, you’ve got the best truck out there.
I hate hate hate the asymmetrical fin, should be back-centered like the Colorado. It has kept me from purchasing a Silverado.
Seriously, the placement of an antenna is that big a deal to you (or anyone else)? It makes me think you have to rearrange your priorties.
You have to be OCD, or is it CDO?
It has nothing to do with cost and or just GM. Most trucks have this offset.
The reasons are easy to see if you really take a look at the options.
#1 reason for this is the sun roof on most of these trucks. Note the Colorado has no sun roof option and the antenna is in the middle in the back. Note that my GTP had one in the back and with the sun roof open would pay havoc with the reception driving in some directions.
#2 They have to work around clearance lights and low doors. The area it is in gives more clearance for both.
The reason for the fender antenna is because it really works better and no clearance issues on the roof. My Canyon clears the door at home buy only a slight amount with the combo radio and satellite antenna. If it was full size it would never make it in. Stub antennas often have reception issues.
The bottom line is it is where it is out of the way the best it can be for various options that may come into play.
The bottom line is that this is not a GM issue as Ford, Ram and others have the same thing and the question comes up often on their forums.
Note most CUV models have them on the rear away from the sun roofs. They have no clearance light options or height issues.
Is this all GM Authority has to worry about instead of fixing their website so I’m not scrolling through a thousand thumbnail pictures to get to the comments when I’m on my phone?
You caught us! We are troglodytes who aim to deliver the worst experience possible! What ever will we do now?! 😉
Sarcasm aside, we “worry” about many things and are aware of the website usability issue you described. An upcoming update we have been working on will resolve this, along with various other improvements all around, in the not-too-distant future.
The first thing I thought of was the wiring , granted from it’s current location to the back of the roof is probably about 18inches or so. With that being said and metal prices all over the place ect, I couldn’t imaging how costly it would be to add those said 18 inches to so many vehicles.
I see the fix in running this same wires in the roof itself , similar to a HD TV antenna, or in the cowl some how. If our cell phones, laptop’s, ect are able to work with out added equipment, then with GM’s technology the shark fin should be moved with no problem .
Fin? What about that ugly front end and crappy looking black interior?
For sure. The fin is the least of the styling problems for the HD pictured.
The answer is so simple. It’s located where it is because it’s easier to service where it is. Reaching it on the center of the roof would present accessibility problems. The technician would have to be suspended over the cab to reach it.
As a life long GM tech I can tell you GM hasn’t cared about how hard or easy it is to service their vehicles for well over two decades, starting with F-body Camaros/Firebirds.
The fins would look a lot better positioned at the end of the cab in the center. It still would have enough room for a sunroof and even a bigger all-glass roof/sunroof or a dual pane sunroof.
Suspended over the cab to service the fin? What are you talking about? If I ever need to fix a fin that’s toward the end of the cab, I would just hop into the truck’s bed. But hey in my 30 years as a tech, I have never seen a fin serviced or replaced. Theyre pretty much bulletproof.
Actually you’d hop into the cab, they hold these f*ckers on with a nut on the bottom that goes through the roofs sheet metal. So that means the headliner has to come down to get them off. And then you have to hop into the bed. My biggest tick with these new 1500 trucks is the ac hook ups. One high and then one next to the compressor on the bottom of the motor. So you have to crawl into the damn engine bay for the evac and charge.
Much to do about absolutely nothing. That ridiculous overhang on the back of the cab is a real turnoff to me.
The current location makes total sense. The full-size truck architecture has five different roofs: regular cab, double cab, crew cab, Tahoe size and Suburban size. If the antenna was centered in the rear, they would have to mount it in five different locations, with five different wiring harnesses for the various lengths back to the OnStar buttons. Having it on the driver side front means the antenna goes on the same spot for every cab style with the same wiring to the OnStar buttons. So much more efficient when you have multiple body styles coming down the assembly line back-to-back. The other factor is slide-in campers. Centered at the rear of the cab would be completely obstructed from the sky and give you zero coverage.
So production efficiency… that’s your excuse.
Production efficiency is another term for penny pinching, cost cutting and bean counting. The body on frame models are GM’s most profitable products and they should be able to spring for five versions of the wiring harness for their bread winning products in the name of a cleaner, better look.
Slide in campers? How many people even have those? Probably 1% or less of those who buy these models.
There must be a better more elegant solution that serves all parties. The single-sided horn looks so old school and out of place…
They produce these vehicles by the millions. Any savings and efficiencies have a big impact on the bottom line.
I would venture that there are fewer people who mount snowplows on their trucks than haul campers, and yet they make design considerations for that market too.
i’m guessing it’s cheaper and easier to install on the assembly where it’s at than having it in the middle. On the assembly line a person could stand outside the vehicle and reach in and install it. If it was located in the middle, on a pickup that worker would have to get in the vehicle on the assembly line to reach it and ergonomically that wouldn’t be so nice and that extra time would cost a little more.
Related to light bars, etc., I was thinking construction rack that overhangs the cab. Possibly a greater chance of destroying the antenna if it’s in the middle, and the metal of the rack would surround every side of the antenna. This offset position keeps it out of the way but still up high where it can be effective.
Another factor is many full size trucks use racks, camper shells and other things that extend over the cab roof so putting anything in the back could be an issue. Mid size trucks seldom use racks.
Fleet sales often are out fitted with different fixtures for company use and this would need to be relocated.
They just put it in the place where it is not in the way for the many options. Cost was not a factor on this one. The cheap plastic door handle more than covered that one.
The real problem is that it’s a butt ugly truck, like thousands of other Chevy owners already have,it’s time to switch to Ram, a far better truck.
I didn’t even notice the shark fin until you pointed it out… now it’s all I can see and it bugs me.
I would say it’s in the location to cut down on interference. Say someone has a loading rack on hauling pipe or a camper is in the area where they mount it. It’s no big deal it’s just up front out of the way.
Chevy you should redesign the side mirrors and make them the antenas for the GPS and the radio then you’d solve all your design problems . and remember no other truck has that option or run the antena along t
Side the windsheild. Before tesla figures this out ….
my God how moronic, if it was on a import you would give it 5 stars.. jeez does every one hate America?
I personally think the antenna would look better in the center towards the rear, however in its current place its a bit cheaper and easier to build different cab sizes. Remember, not everyone buys crew cabs trucks. Not to mention, in vehicles with sunroofs I feel like it would be in the way a decent bit considering how many controls/motors/wires are shoved in the roof already.
I also agree with a few commenters who claimed that it would be subject to more damage in the rear. Once a ladder rack is installed….especially in work trucks, that area is subject to damage by pipe, wood….you name it.
Now that GM doesn’t offer the SBRC in North America, I have to buy a Ford. As far as the antenna goes, who cares at this point. But it looks just fine where it is.
To bad they cant go back to the old square body days and out it in the windshield.
I would prefer it in the middle, left to right. As it is now, it’s in the way when trying to clear our 7 months of snow off of the roof.
They could just move the roof over and, walla-viola…fixed!
Sorry. I didn’t mean to post twice.
I was at work * oops! And it said there was an error. GM Authority’s site went into a blue pixilated seizure. ???
So, I reposted. Not my bad. I swear.
They could just move the roof over and, walla-viola…problem fixed!
Rant-again. ?
How many times do I have to prove I’m not a robot?
I poop at least twice a day.
That should be enough proof?
?????
Alex, or, whomever is in charge?
Please update your website to be compliant with the year 2019.
Proving I’m not a robot is annoying. But, there are more issues. Especially while using my iPhone.
When I go through the ridiculous-I am not a robot bc I can select fuzzy 1998 pictures to prove it- I also get error prompts, but then it goes through anyway??
Love this site, but I can’t stand how behind it is compared to the other car sites I visit and engage in.
Is it lack of funding?
Robot time?
One thing that could help here and separate GM from all the other trucks doing this.
Offer the body color fin like used on the Cadillac to better blend it in.
It needs to be moved to the rear and center . As much as we pay for the vehicle it should be no problem to relocate the fin .
I like the color ideal but really who cares.
No big deal to me. I’m used to where it is and really don’t even notice it.
This story is not worth even typing.Holy cow!Not even an issue in my opinion.I have a new 2019 Silverado Trail Boss Z71 Custom.I love everything about it and no issues at all.Try throwing necessary shade on the city slicker Ram(chick truck) and the Junk150.I wouldn’t buy one of those(I won’t call them trucks) pos’s with someone else’s money.
hey I’ve owned both Ram and Chevrolet.. the Ram is a good truck but the Chevrolet is a much better truck. I had problems with the Hemi 5.7, never had an engine problem with a Chevrolet
If you locate the antenna in the middle of the roof, and place anything above it, you may completely block the signal. Non-issue
As a retired GM manufacturing engineer, I can tell you the antenna location is completely due to ergonomics. GM manufacturing is very careful to design safe assembly operations and there are sophisticated algorithms to evaluate every job on the line. Placing the antenna fin without an extended reach by the operator dictates it to be to the side. If you have ever toured a GM truck plant, you would realize that the cabs are built on a separate line than the boxes. There is no way we would ever allow an operator to climb to the middle of the conveyor chain to place the antenna at the front or back center of the roof.
Does the writer always complain and nitpick over tiny stuff like this, or is he running out of stuff to write about? Seriously find something more indepth to write about.
It looks like a total afterthought.
You mean much like the thumbnails on this website are lined up on the far left side of the screen??? I hadn’t noticed. *insert sarcasm*
While on the trucks it doesn’t really bother me, on the SUVs and on the Escalade in particular, it needs to be centered. It’s small details like this that are unprepossessing on a luxury product.
I have a 2008 Suburban Z71. It has the fin and I don’t notice it and this article does not make it more noticeable. That said I would rather read about how small the tires and wells arw in the trail boss and how small the box looks even if it is a bit longer. 2nd to that how bad the front of the 2500 looks.
Back in the old days, the radio antenna was a metal pole usually on the driver’s side front fender.
Put the fin there please
Yes! Move it back by the roof brake light.
It’s in that spot so you use less wiring and because if it breaks, you don’t have to remove the entire headliner to fix it. So that means if you move it, then they will charge extra labor to take the headliner out as well as the antenna. I wish more cars had these like this so we wouldn’t have to take the damn ceiling out to fix your XM on your Accord.
*I work for a Honda dealer and life is cruel to a non-GM tech*
I would have to say that I completely agree that the asymmetry the antenna creates is frustrating, sloppy. It makes the truck look cockeyed or even snagle toothed. I feel like cars and trucks look best when completely symmetrical. Even exhaust outlets on one side bug me. Fuel filler doors I understand make no sense to have on both sides but at least they are flush with the body
Good hand hold where it’s at when waxing roof.
Not a issue
The so called fin is on the back of the equinox’s in the middle , And no antenna on the fender , my 16 Silverado has both , why ? My wife’s Acadia has the windshield washers in the hood , GM engineers could come up with a better place ? With the fin over the drivers door means one size fits all , standard cab or double cab or crew cab ,SMH
Who cares, really? Nothing better to worry about? It works what more can you ask for?
I would worry more about all the ones that leak! The spot is fine.
I like symmetry. I also like redundancy and effective antennae. Why not have two, one on the left and one on the right? If they worked together maybe they could have a bit lower profile that way.
I like where it is because it is less likely to be obstructed being near the center of the street instead of near the edge where trees or other objects are likely to be able to block satellite radio signal.
Holy unbelievableness…really? You wasted your time as a ‘writer’ (term used very loosely) to point out something this ridiculous? Ok, allow me to educate you, as you seem to have a lack of education…
First, the ‘fin’ would look goofy centered, and would follow everyone else’s cue and be just another sheep of a company to put it in the center.
Second, it’s for easier service stability. If it does need to be replaced or connections checked it is much easier in its current location then to put some kind of scaffolding over the vehicle in order to access it at the center point…or step on someone’s hood…
Your total lack of everything a pickup truck is commonly used for is stunning. Just because you went to school and have a degree in writing, if you want to call it that, is laughable. I could write circles around you but I will never get hired as a writer because I don’t have a fancy degree. I also have a brain, and I actually use it, so that in itself disqualifies me above all. You mentioned putting the antenna at the rear of the cab. I’m sure everyone who uses GPS and satellite radio and a truck camper would really appreciate the placement of the antenna at the rear of the cab where it would effectively be blocked from receiving any kind of a signal whatsoever. Do everyone a favor, if you are going to continue to write articles in the automotive sector, stick to a Prius or something that you might actually know something about and leave our pickup trucks alone. There’s enough idiots in the world without you adding to it.
Service the antenna??? What?? You know antennas don’t require an oil change every 3000 miles! Now if it gets damaged, you’ll have to drop the headliner down to replace it. But if it was in the center, then All you’d do is remove the upper console for access, and trust me, you won’t need a scaffold to reach it, I wash my trucks roof all the time and don’t have problem reaching the center. Besides how often do people break their antennas?
The worst idea they had is that they decided to mount the mirrors in the middle of the door. What’s wrong with where they have been for 30 years?
Shark fins are so 90’s, and it doesn’t look good off centered either . Why not make a low profile antenna and place it on back of the cab where you don’t see it, or better yet, hide it under that rear plastic spoiler that is above the rear glass.
To throw in another aspect, RF loss over any distance is high, even in a good coax, and the longer the distance between your RF source and the antenna, the more loss you incur pretty much exponentially. I’m sure an EE can provide the exact answer. So, from that perspective, this is probably a very good placement.
The suggestion of putting it on the tailgate is what woke me up to that aspect. There’s no way you’d get a signal worth anything with a cable run that long.
This is the hottest thread on GM Authority I’ve seen in a very long time. Very entertaining.
It is so when you have a ladder going over the roof of the cab the antenna doesn’t get broken off.
It needs to be off to the side to not interfere.
Its located there to make it easier to install.
In the middle of the roof makes the reach to far. It’s in the middle on the Equinox and requires a extension tool to hold the antenna while the operator fishes dangling wires through a small hole.
Nowadays ergonomics in manufacturing is taken seriously.
It must be a slow day in auto news to report on fin placement! Go find something else to complain about to justify your job. You thought it relevant enough to write an article about a fin? Even worse, someone approved the publishing of such an article.
Order one with a moonroof and you will understand why it was put there.
On mine, control panel and motor are located front center of moonroof, antenna is positioned in the only logical place. Looks fine.
There is only one and antena so there’s nothing to be symmetrical about it. Placing it in the center doesn’t give it symmetry either and would look nowhere near as esthetically appealing. The contrast with the surrounding symmetry of everything else looks amazing!! I’m sure GM spent millions of dollars and engineering and deciding just that. Everything we say including you Mr. Writer is just a simple opinion and my opinion is that your opinion sucks!!
Also some of you have some very valid points but seem to not know very much if anything about RF ?
Yes obviously and generally (not always) the closer to the rf outsource you are with your receiving equipment the stronger the signal… However for anybody that says you’re not gonna get any type of signal at all from the back of the cab or tailgate YOU ARE IGNORANT to say things so CONFIDENTLY that you know NOTHING about ? moving 2′ across the top of the cab won’t even be noticeable in RF signal strength! It will diminish very miniscule not significantly… I know for a fact that I run Wi-Fi out of my trunk driving down the freeway 80 mile an hour and shoot signal to vehicles following me running business on laptops lol pretty sure that speaks volumes about and smashes these theories of moving it within its own vehicle space ?
