I know when you make a antenna shorter the feedline would get longer but is there anything elese I would need to do
The mag mount is so big it will not fit anywhere elese on the roof there are groves on the roof mag mount can not fit between them
loosen the bolts that hold the mags and plates an adjust them to where they will fit
can you stand on the hood of your van and take a few pictures
I went to the cb shop today here is the mount to end all mounts antenna is driver side body mounted with a stargun mount had to cut about 10" to 14" off the whip it is now about 3ft lower now 1 to 1 @ 52 to 56 ohms
you do know those coils need to be above the roof ? youre mostly gonna have what little signal you tx or rx from the drivers side .
