New install on a '19 SuperDuty, and I am having issues tuning and lowering the SWR (using the built in SWR reading on the Bearcat 880).
4' Firestick FS mounted on a diamond plate toolbox. I have a bonding strap from the mount (between mount and toolbox) to the bed (bare metal), and also from the bed to the frame (again, both bare metal).
CAL is dialed in, RF check shows as a PASS, ANT shows as a FAIL? I am dialed in to ~3 SWR on channels 1 and 40 (tuning screw is all the way in). I am at a loss at this point.
I have checked continuity since the Bearcat is complaining about the Antenna, but everything checks out...
Are the Bearcat readings reliable?
Any thoughts on lowering the SWR further? My next step is a bond between the bed and cab.
I am not trying to win on distance or anything, just need a couple miles range while towing.
