PL259 Jumper, Ancable 3-Feet 50 Ohm Low Loss RG58 Coax Cable with PL-259 Connectors for Jeep Wrangler CB installation

Product Information

Also, look for an amplifier that has reverse polarity protection. Polarity reversal can cause immense damage to the amplifier. That’s the reason why most of the amplifiers that you can find today come with the safeguard. After testing for days and pitching it against many other CB linear amplifier options available in the market, I found MegaWatt S-400 as one of the best that your money can buy. Measurements and determination of short or long conditions are the same as the single antenna procedure. However, when tuning co-phased antennas, if you adjust one antenna, it is advisable to adjust the other in equal amounts to keep them in perfect balance. COAX CABLE PROCESSING with FIRESTIK CONNECTORS

FCC rules dictate that your CB radio should have a power output within 4 Watts and 12 Watts. This means that the input power of your CB linear amplifier should always be within that range.A normal 4-watt CB radio will give you a range of up to 20 miles in ideal conditions. The amplifier you buy should depend on how far you want to reach. If your target is to reach about 65 to 70 miles, a 100-watt amplifier should work perfectly fine. How to take care of a CB amplifier? RG-58 type coax is 50 ohm cable and is used for single antenna installations of CB, scanner, 2-meter, and 10-meter Firestik antennas. RG-8 and RG-8X are other common coax types that can be used on single antenna installations. The manufacturer did a remarkable job of maintaining voltage stability for the MegaWatt S-400-12 device. It also comes with protection against unexpected power surges, a grounded power cord, and an automatic shut down for protection against short circuit. Remove 1/2″ ( 12 mm) of the center conductor insulation and dress by twisting all strands into one wire.

To tune an antenna, use an SWR meter attached between the transmitter and antenna feed-line. Depending on the meter, you can either use a button on the meter to generate a signal on the various channels, or key the microphone on the CB transceiver to generate a signal while you look at the SWR reading. In general, if the SWR never goes above 1.5:1, you’re in good shape. If the SWR does go above 1.5:1, then watch the meter on different frequencies to see the trend develop: The SWR will be greater either on the higher channels or the lower. If the SWR is greater on the lower channels, then try gradually lengthening the antenna by moving it in the base. If the SWR is greater on the higher channels, try shortening the antenna. Remove (unscrew) knurled barrel sleeve from main connector and drop over coax. Make sure that the internal threads are up (see Diagram C). Remove 1/2″ (12 mm) of the center conductor insulation and dress by twisting all strands into one wire. Crimp and/or solder terminal(s) to appropriate wire. In most cases, the larger of the two terminals will go on the center conductor. If both terminals are the same size but one has it’s own insulation, this should be used on the center conductor. If SWR is in the “red zone” on all channels, you probably have an electrical short in your coax connectors, or your mounting stud was installed incorrectly and is shorted. Do not operate your radio until the problem is found, serious damage can occur to your radio.

The CB linear amplifier is the most powerful of all. These are designed for reconditioning the outgoing signals. These are the best in the market because they are not only capable of providing the best performance but also increase the coverage distance with high power. A citizens band (CB) radio antenna is a device designed to do two things: It captures Radio Frequency signals that are then converted to electrical signals by the receiver, and it takes electrical signals from the transmitter and converts them into radio-frequency signals. This second function is where tuning comes into play, because an antenna has to effectively radiate radio-frequency signals, something that’s done best when the length of the antenna precisely matches the wavelength of the transmitted radio frequency. Most, but not all, manufacturers pre-tune their mobile antennas on a test bench. To protect your radio’s circuitry and achieve optimum performance, mobile transmitting antennas (CB, cell phone, amateur, etc.) need to be tuned on the vehicle.
