Is the toolbox itself bonded solidly to the bed of the vehicle, and from there to the chassis? Maybe all four corners of the toolbox?Ok, New area for my 102" whip. On the rear bumper corner on my pickup it has great low swr 1.1
But I want to move it to the center of my alum toolbox . When installed to the lower center it looked great but swr was 2.5 Grounds are all good. Is it because the antenna is mounted so low down in the bed of the pickup?
