![]() ![]() Never tune inside or next to aīuilding, near or under trees, near or under power lines, and never with a Radiation." Tune your antennas in an open area. Transmitting antennas are sensitive to objects in their "near field of Not operate your CB without an antenna or dummy load. #Cb antenna coax need better ears tv#Don't use a TV antenna or an AM/FM antenna for your CB. Make sure that the antenna you are using is the right antenna for yourĪpplication. Operating with high SWR will probably damage your CB's internal circuits. Do not attempt to tune the antenna until the short is fixed. SWR that pegs the needle on all channels almost always indicates a short in Will have coaxial center pin to ground continuity. Also, Firestik "No Ground Plane" antenna kits ![]() Loaded antennas use a center tap design and there will be continuity from (See "Testing Continuity") Exceptions: Some base Don't transmit! If you do notįind continuity between the center pin of the coax and the antenna base, you Outer threaded housing, you may have a short. If you have continuity between the center pin of the connector and the Before transmitting, you should check your antenna system for shorts or Mobile transmitting antennas (CB, cell phone, amateur, etc.) need to be tuned To protect your radio's circuitry and achieve optimum performance, Most, but not all, manufacturers pre-tune their mobile antennas on a testīench. In "no-ground-plane" systems, the coax shield Installations with standard antenna systems, the vehicle metal (body, frame,Įtc.) acts as the ground plane. Neither is more important than the other. The antenna is the reactive unit, the ground All mobile and base transmitting antennas need counter-poise, moreĬommonly called ground plane. ![]() Radios antenna jack, unless you have extra money to buy another radio, or know a good repairman. "dummy load" (non-radiating antenna simulating device) connected to the Never key up or attempt to operate your CB without a working antenna or The fact that a physical 1/4 wave is 108 inches. Inches long and mobile 1/4 wave antennas can be anywhere from 12-60 inches long in spite of Make that claim, ask them how a handheld CB can have a 1/4 wave antenna 8 They are wrong! Physical lengthĪnd ground wave performance are not the same. Some "experts" may "claim" 5/8 wave mobile antennas are not possible because they would need to be 23 feet high. The knowledge gained from the best book on theory will not necessarily produce the best antenna design. While theory is a good starting place.experience is invaluable when it comes to real problems. There isĪntenna theory and there is antenna reality. Beware of information from "experts" (real or self-proclaimed).
