I got my cb and antenna installed and am receiving with a lot of noise, almost to a point of uselessness. I haven't tuned the antenna yet, but was expecting to at least be able to receive with some measure of clarity. One potential problem is the non-tuned antenna, but others may be the mirror-mounted antenna which is potentially not grounded (this I will rectify). Another potential issue is the cigarette lighter adaptor, should I run directly to the battery? Thanks in advance for any help.
