I have 1 of these on a mag mount of the roof our suv it does great, but I know I am not getting full strength. I know on my 40T I cut 6" off the whip and getting awesome results. I know I may need to cut the whip down on 20m so those of you running this antenna what length did you take off?

What someone else took off and what you might have to take off will not necessarily be the same.  Different installations (different vehicle, different mounting location, different size of "ground plane") will make each somewhat unique.  I would suggest you shorten it in small increments and then using an antenna analyzer look for SWR changes at the center frequency where you want the SWR to be the lowest.

I suggest replacing the stainless whip with a piece of stiff wire then tuning the antenna. Once the antenna is tuned cut stainless whip to match stiff wire. It saves on buying whips.

I know on mine, I am running a spring on my mount, and have had to cut off at least 4" to get the swr even around 3.0.

I may leave the way it is,don't have a meter to test it. I did make a contact in Indonesia yesterday so it can't be to far off

It sounds like you need to get an SWR meter so you can measure what is going on with your antennas. Otherwise you are just playing a guessing game.
