well, i know this is going to start a bit of a thing, but according to accepted antenna theory; a vertical ground plane antenna works off of its capacitance to ground, and if you don't isolate it from it's metal mast, you have a leaky capacitor.

that being said, there is good reason (safety) for having a metal mast going straight to the ground, and i believe the engineers at where ever decided what to put in CB antenna instruction books cared more about liability than correct antenna design.

also, from what i have read elsewhere on this forum, you have to isolate the antenna to the point where the metal mast is below where the radials hang or they will just induce their currents into the mast. If that is incorrect, someone please let me know.
