I am new to CB's and need some assistance. I installed my $40 RadioShack cb over the weekend. I installed it directly to the battery and it works fine. The antenna is a Firefly 3' with a tunable tip. I have it installed in the back of the Jeep with a tire carrier mount. I initially tested the setup without the antenna grounded and I was able to send and receive with okay range. So I then ran the ground for the antenna to the front of the jeep where I have my KC lights and the radio grounded. When I tested it again I got nothing. Not even static. Could the ground be interfering?
