When the nut or bolt contact the mount, this fails. The whole purpose of an antenna stud is to isolate the antenna from ground. There are nylon washers that prevent this, but they are sometimes left out or installed improperly. Click here for information on testing CB Coax StudĪ short occurs in the antenna stud when the antenna coupling nut (where the antenna screws in), or the bolt, makes contact with the mount. If there is continuity, replace the cable. Use a multimeter to check for continuity between the center conductor and the shield. To test for this disconnect the coax from the CB radio and CB antenna mount. This can happen as a result of a defect from the factory, or a break in the cable. CoaxĪ short occurs in a CB Coax when the shield is making contact with the center conductor. There are two places a short can occur in a CB antenna system, in the coax and in the antenna stud.
The most common cause of a high SWR is an antenna shorted to ground. Also make sure the doors and hood are closed on the vehicle. Make sure you are not too close to buildings, trees, other vehicles, etc. If you are not sure, check our guide describing how to tune your CB antenna. The first thing you need to make sure of is that you are taking SWR readings correctly. LocationĪnd by this, we mean where your vehicle is when you are taking readings. Improper storage of your coax (such as a circular style) could result in RF (radio frequency) issues that could interfere with your signal. Store any additional coax in a figure 8 style, about a foot in length, and loosely bound in the center with a zip tie. Verify that your coax is not crimped, bent, or crushed. Run the coax in a large figure 8 or purposely run the coax in a longer path to the radio. Coiling the coax up will cause the cable to mimic the coil in the antenna, creating signal feedback. Make sure that any slack you have in the CB coax is not coiled up.
Times your normal power! The design uses a 16-foot boom with six scientifically-spaced elements and a quad reflector to obtain the best combination of gain and front-to-back ratio.Often times, especially when you are using the factory recommended 18 feet of coax, you will have extra coax between the antenna and CB radio. Developed to fill the need for top performance, dual polarity operation, the Shooting Star has a gain of 14dB. When performance at a price is your main consideration, look at the 8-element Shooting Star. View the manufactures page for SHOOTINGSTAR We had 2 of this item in stock at the time of the last update.
