 I have the Silverado LTZ and I'm wondering if anyone has looked into this or knowledge of replacing these antennas, with either aftermarket of other GM models that would work, without losing anything.

 

I'm still learning this truck and don't know if this antenna is specific to the model.  Wouldn't think so, but I ask anyways and my issue with mine is it's a couple inches too tall when coming in or out of my garage. Being in Florida, I have high wind brackets on my garage door and the antenna hits the bracket.  

 

Thanks in advance for any information that can be passed along.

Can use pretty much most aftermarket ones, or if your the handy type cut yours down, reattach the ball and it will just like a shorty oem antenna

I just replaced mine with a 4" Stubby. Same issue as OP...garage door height barely clears roof, and OE antenna drags.

Superior customer service from these folks. The one they sent wouldn't thread on. Either it was wrong, or as they said, there are 2 different thread patterns in use for 20's and 21's. Either way, they sent me the variant model free of charge and made the exchange super easy. Very quick to respond, quick to ship.

 

With *any* shorter antenna, your reception will be affected. Most notably, AM stations in rural areas will be hard to get. If you are in-town and mostly listen to FM, you shouldn't notice much if any loss except maybe for some distant FM stations. XM or other signals are unaffected - different antenna for those.

Excellent, thanks all! 

A little more research into the marine and ham radio industries, to see if anything applicable, before I decide.  

 

I did manage to have an old thread come up, that didn't from my original search -

I just received mine and have the same issue, glad to hear they take care of it easily.

Amazon Special. Pretty good AM/FM reception.

Which brand was this one? I may try one of the stubbies, but I've also looked at some of these taller versions.  The only wire wrapped ones I came across, was of the OE whip style.

I have a Sierra 1500. I initially tried the popular aftermarket rubberized stubby you find on Amazon. It performed fine and required a thread adapter which was included. I only kept it on for a few months because it got tired of noticing it all the time. Although it was short, the thickness of it stood out to me. Just about all of my front seat passengers would ask, "Was that always there?", referring to the "covert-stealthy stubby antenna.

 

I ended up replacing it with a shorter version of the factory antenna. It is 7 inches tall and does not require a thread adapter. Looks stock but a lot shorter. Performance of this antenna seems to be the same as the stock one. All the same stations come in fine.

 

I found it at theantennasource.com. Free shipping was quicker than I expected.

They also have 9, 12, 15, 21, 24 and 27 inch versions in black. Other sizes come in stainless.

      2018 Silverado Console USB Port Not Working

      By Tbhats2130 · Posted

      My centre console USB ports haven’t been working and the one in the glovebox is starting to act up. When I plug my phone into the cord the radio will go black and stop playing, and the CarPlay is inconsistent.   I checked the fuses and they were fine. I changed the USB port out and still nothing. Hoping for some advice on what I should be looking at.

      The truck is a 1995 Chevrolet S10 Blazer, 4.3 VIN "W" engine. :cracks knuckles:   On a whim - because I needed a headache - this truck was for sale so I stopped to take a look. Doesn't run. Well, it does, but barely. Long crank, choppy idle, bad misfire(s), it REEKS of fuel. I can DO this..I'm thinking. Diamond in the rough. One owner until last year. A young guy is selling it, he bought it 6 months ago. It stranded him more than once, he's got a newborn. It was in the shop 10 days ago and he "thinks" they said it needs a new fuel injection system. He can't put any more money into it, needs it gone. I was thinking of upgrading my Macbook, which is a total want, not a need. For less than the price of a new laptop I can have fun for months tinkering on this truck and enjoying it. I'm taking this truck home. The guy was beyond thrilled, his wife was there, she thanked me profusely, I could tell they were hurting. They seemed like good people in a bind.   Some parts, a wash, maybe a set of tires, and I can have a few months of fun and then turn it for beer money (or the next project).   Sure enough, there's a work order from a shop last week in the INCHES of paperwork on this truck dating back to when the first owner bought it. They put a new distributor in it, fuel injection work describes basically opening the plenum and putting it back together. He said he couldn't afford any more work so he had them button it up and that's when he put it up for sale.   I'm not well versed in 4.3. I did discover 1995 uses the 1992-1995 SCPI "Spider" injector which is riddled with issues from splitting lines, clogged or cracked poppet valves and plastic spider legs that crumble over time. Cool. I'll just order me a ne---. Oh, the auto parts store doesn't have it? Rock Auto doesn't have it. eBay? $$$$$$ for used. These are UNAVAILABLE period end of story unless you know "a guy" who's still got one in a box somewhere.   Can't upgrade to the '96-'04 injector, it's a different plenum, wiring/pinout and sensor config.   There are a few kinda "know a guy" -guy rebuild services for these injectors out there for about $350. Okay, Okay... I'd like to know if anyone has used them? Anyone got a lead on these crappy 92-95 spiders?   I also don't want to send MY spider to Narnia and back without knowing if that's truly the problem. I guess I'll need to pull apart the plenum and do some digging.   I was also thrown for a loop. This 1995 model year truck has an OBD-II connector. The interface is decidedly not OBD-II. I can read and reset trouble codes and view live data, but there's not a lot of data. Like misfire count and on what cylinder, that's not there. It's OBD-1.5.   Nothing is ever easy. Now it makes sense why this guy wanted to disappear this thing for cheap. I'm guessing the shop told him the injector is toast, the part is unobtainable and they're not going to sort sending the thing to a rando offering rebuild service on craigslist, and the kid likely can't be without a working car for 3 weeks even if they'd facilitate that.   Experience with these early SCPI's? Stories? Things to check? Sympathy? (..Nah...)   This can sit until I sort it. But I haven't had a problem with a vehicle I couldn't easily solve in a long time.

      I have four that read by the dash 8 to 10% better than miles/pump calculations and I have one that is spot on.
