CB Antenna observation...
I bought a used OEM CB mount from a member here (thanks angelo!). I ordered the OEM coax. Yesterday I assembled everything, and to make a long story a little shorter...it didn't work well. I went to trouble shooting and discovered that the coil at the base of the antenna that threads into the mount, is not isolated electronically from the mount. A continuity test of the coil proved that there is no isolation from antenna orifice to the mounting threads.
It is my experience that the coax core, that feeds the antenna, should be insulated and separate from the braided outer portion of the coax. With "this" setup, the signal from the core wire is fed right back to ground through the base load coil. Not good for the radio. Either the coil is bad (shouldn't conduct back to ground) or there is a non conducting piece missing between the coil and the mount. I did notice that the OEM coax core that feeds up through the antenna mount had extra length that would accommodate an extra piece. I looked on the parts fiche and didn't see anything in addition to what I have, so......?
Am I missing something?
