A little antenna help...

A little antenna help...

Postby TARDIS_1994 [OP] » August 10th 2012, 4:31pm

Hello all,

I wish I woulda found this site earlier in my travels. I am not mechanically inclined by nature, but I have to thank my Astro for teaching me about: water pumps, alternators, window motors, brakes, how to charge an AC system, door locks and mecs, and a 3 day tour of the muffer system (suffice to say OEM parts do not mean they actually fit, and the choice of paying GM $350 or O'Reily's $53).

While fixing the muffler, a sunscreen lofted over me to keep me cool also had the effect of putting too much strain on the antenna, which snapped off. A trip to Pick and Pull and I have a replacement, but it was exposed pretty well (no dash / vents, thanks whoever for wrecking it completely with a sledge...). I have no point of reference and Haynes has no info.

How the heck do I get to it without a major teardown of the dash? I know that the wire from the mount passes thru the firewall and it plugs into the lead going to the radio at a mount bracket behind the firewall. How the heck do I get to it? Any help would be appreciated.

I actually have no antenna on mine by choice. I used a single strand of copper wire. Soldered it to the antenna base. Ran it up the side of the window under the plastic window trim. Works great.

Choice B also easy. Advanced auto sells a in dash antenna with booster for custom stuff. My brother found it for his charger. He dont want the factory antenna. It is 15 bucks I think he said.

I'm running w/o an antenna too, just gets in the way when you're scraping ice/snow off your windshield. Looks cleaner too.

Well,on a 1996 its showing to remove wiper arms,wiper cowl(air vent),and then under the cowl you'll see the attenna cable with a metal mount,remove the 2 bolts.You'll see that this is the cable entry point through the firewall,going through a rubber grommett.Now remove the radio,disconnect the attenna cable.
Now you have to loosen/remove the dash gauge cluster(instrument panel) which is probably the hardest part.You don't disconnect anything,just pull it back to access the attenna cable and UN-CLIP it from the HVAC control module.Now pull the cable back out through the firewall and cowl area.Unthread the attenna mast and pull it off.And that's it.Just reassemble in the reverse order.
These are what the GM manual say to do,should be correct.

If the antenna broke, it's likely that the coax cable connector is still intact and perhaps still connected to the base of the broken antenna. Remove the plastic cowl vent, it requires a T-15 Torx driver I think, then you should be able to reach the underside of the OEM antenna. Remove the thing in obvious fashion. Unscrew the antenna coaxial cable connector on the base of the old antenna, replace with new antenna, connect THAT new antenna to the existing coax cable.

All of that is assuming that your replacement antenna uses the same style connector as the OEM style. It's very likely that it does.

Or you could always mount a few new external antennas...

Awesome Truck Mr.Lumpy.And your so right.Why go through all the OEM removal hassles when your simpler replacement is the way to do it!There you go,TARDIS_1994.
I forget to think "outside the box" sometimes.
