Wilson 2k. Whats typical cut off?

It's going to be different on every vehicle

 

? You can't start cutting till you pull your swr's on 1 and 40. Even then, trim less than you think you should and run swr again. Sometimes you luck out and don't even need to trim it

 

I installed a Wilson 5000 on a Chevy Avalanche and got a perfect match the first time around without even having to trim the whip

 

Rusty, there is or should be instructions with the antenna that explains this step by step. If they were not there, then go here

Well first thing you need to do is use an external swr meter. Then go from there.

 

I recently installed same antenna on a KW t800
With a 980ssb, out of the box works great
Although its kind of tall and hits some of the loading racks and a few bridges

 

First things first. Check rf grounds.
Better to use antenna analyzer. If no resonant point grounds are bad.

 

probably couldn't do that again in your lifetime! !!!!!!!
