CB Radio Shed SWR Issues

[222DBFL]

No counterpoise. No metal under that 102" whip. You need to either add 4 102" radials and possibly lengthen the center whip to 108", but you need to at least have some ground plane under that antenna for it to work the way you have it mounted and being used. A large Metal plate and a 6" SS HD spring might help with what you have now. Get a 3' x 3' or larger metal plate under the antenna. But you really need 4 ground radials I believe. With the setup you have, you would be better off using a extendable fishing Pole or pvc and make yourself a 1/2 wave vertical dipole. You either need to change antennas or do the above mentioned. You gotta have counterpoise!! Bottom line. No metal under that antenna equals no good. JMHO.
