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

Product Information

For SSB, the maximum output is 300 watts for 10 watts of input. If the input drops to 5 watts, the maximum output for SSB is 250 watts. The minimum allowed input for SSB is 2 watts.

VSWR (swar) this is a ratio of the reflected power (reverse voltage) on your transmission line, the coax. It is just that, a ratio, so there is no such thing as SWAR. It is Voltage Standing wave ratio and the closer you can get to 1:1 the better. Beware of the wire wound mobile antennas mentioned in ads that claim them to be “full-wave” or “wave and a half”. At best, you are being deceived by the misleading association of wire length to actual performance characteristics. Wire length, for all intents and purposes, is irrelevant. With “very” few exceptions, antennas must function as a 1/4 wave or 5/8 wave to be useful on mobile installations. For example, Firestik and Firestik II antennas between 2 foot and 5 foot have a radiation pattern similar to a 5/8 wave reference antenna. However, wire lengths range from 20 feet to 32 feet (0.6 to 0.9 of a full wave length). If wire length was relevant, each antenna would need 22.5 feet of wire.Use end of nail or other pointed object to unbraid the copper shield. Trim to approximately 1/4″ (6mm) long all the way around. In almost every instance, once you get the same SWR reading on channels 1 and 40, further antenna tuning will not improve the readings. If the SWR is still over 2:1, you have other problems to conquer. Exception: There are rare occasions when the ground plane is so small or large that the system is way out of phase (especially with high-performance antennas). If you have high SWR on all channels and have confirmed that you have no opens or shorts in the feedline, try making a small tuning adjustment in the antenna. There are times when the SWR will drop equally across all channels under unusual ground plane conditions. If you find this to be the case, carefully adjust the antenna. Remove 1/2″ (12 mm) of the center conductor insulation and dress by twisting all strands into one wire. 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?

When attaching the ground wire use a star washer to get a good bite into the metal. Most problems with wire jobs are due to a poor grounding.Use end of nail or other pointed object to unbraid the copper shield. Trim to approximately 1/2″ (12mm) long all the way around. The limited range of CB radios, has forever, been the Achilles Heel for the CBers. But you don’t have to stay satisfied with what you have. You can always squeeze out high-quality signals from your CB radio with a CB linear amplifier. If budget is your concern, then buy MegaWatt S-350-12. Otherwise, it’s better to buy the MegaWatt S-450-12 model as it offers 450 watts output. John Remember, all transmitting antennas need ground plane (counterpoise). Base antennas, much like “no ground plane” antennas, build it in. Do not use mobile antennas for base station applications unless you know how to build your own ground plane. For AM and FM mode, the general output range for the amp is 100 watts, but the maximum output is 150 at 10W input. The minimum input it accepts for AM and FM is 1 watt.
