Thread: Cheap way to shave the antenna on a NBS truck!

  1. #1
    Whataburger from TexasTruckScene.com clued me in to this cheap and easy mod and I thought I should share

    The antenna on the NBS trucks goes through the wiper cowl corner, not the fender like the OBS trucks. Escalades have the antenna in their back glass I think, so their cowl corner doesn't have the hole in it.

    Parts needed:
    Escalade cowl corner - GM part number 15287179 (got mine for about $10 shipped from partszoneonline.com)
    1 zip tie
    1 bolt/nut (not sure of the size, mine was 3/8" bolt head and about 1/4" in diameter at the threads)

    Remove the antenna and then pop off the cowl corner. It has 3 clips that hold it in place. Then you unbolt the base of the antenna (3 screws) and lay it down, running it parallel with the fender. Now attach the antenna base to the "L" bracket. I used an old bolt that I had in my tool box to attach the antenna to the "L" bracket. Now attach the "L" bracket to the antenna mount using one of the original antenna screws. Reattach the antenna to the antenna base. Now secure the antenna to the fender using the zip tie towards the end of the antenna. There is an opening in the fender well that you can thread the zip tie through. Install the escalade cowl corner and you're done.

    I noticed a little reception loss, but not enough to be concerned with. Enjoy

    My truck was filthy at the time, but you get the idea

    they just look weird without an antenna to me. im sure im in the minority on this one but i think a short billet antenna looks better.

    nice! i liked the idea of the hidden antenna from stylinconcepts, but u lose AM radio functions. i know i rarely listen to AM radio but still sometimes the only way to listen to the football or baseball or hockey or basketball games is that way. maybe ill get me one of those satelite tv systems and mount it on my roof...

    The hidden antenna thing might help, but I couldn&#39;t justify the cost of it (&#036;50) vs. the cost of the stocker (&#036;0)

    This is a cheap and easy upgrade. I&#39;m so glad to have found this on here. My cowl piece is on order, and the rest has been taken care of already. I always wanted to rid of that antenna, as I have XM. Now I can have my cake and eat it too. Thank you to the guy who came up with this ingenious idea.

    Oh, yeah, noob here. Gotta&#39; Victory Red 2004 RC/SB Z71.
