Anybody have a part number for a longer Antenna than stock antenna ??

Why do you need a longer antenna?

Looks 

I like the look of them as they lean back off roading or going fast

I dont think GM has one so no part number. You may need a CB radio antenna or something.

It will look weird im sure in the original location.

Have you done this before? I'm not finding anything. The reason is that the factory antenna and ones similar to it are close to 1/4 wavelength for the frequency they receive. Going longer isn't going to improve reception that much in a monopole configuration. There just isn't a reason to make one beyond about 31 inches.

If this is for aesthetics, get a big CB antenna and mount it however you want. That'll have some whip to it.

There's some whip. 55" from the roof. Don't forget it's there and hit the drive thru for some chickie nugs!

I am in shock someone who actually understands RF technology!

You don't put a longer whip on your OEM antenna mount, a longer whip will put too much stress on the mount and most likely break it. I've seen plenty of people use whip style pole for off roading on sand dunes / hills, but never in place of their radio antenna.

I'm an engineer. Not RF, but I know enough about it to be a little ahead of the curve.

 

Enough that I built my own base antenna from a 1960s spool of telephone wire that can skip all the way to Ohio from Florida on 4 watts of transmit power. Works on the same principle as the Duga array - transmit outward and upward towards the sky, and if conditions are right, it skips across the atmosphere. Little more challenging with so little power though.
