Suitable for vehicle installs for CB radio and HF amateur radio.== RG-8/U =====RG-8x / Mini-8===thin, This cable is .242" diameter with a #16 AWG stranded center conductor and a foam dielectric. ===RG-8/U===This cable is suitable for 50-75 foot runs in the VHF/UHF range. The cable is considered by some to be obsolete. The cable has a characteristic impedance of 50Ω.This cable is suitable for 50-75 foot runs in the VHF/UHF range. The cable is considered by some to be obsolete. The cable has a characteristic impedance of 50Ω. This cable is .405" in diameter with a #13 AWG center conductor and a solid polyethylene dielectric. == RG-213 =====RG-213===== UR-67 =====UR-67===== LMR-400 =====LMR-400===== Belden 9913 =====Belden 9913=====Jumper (Patch) Cable==From the transceiver to an antenna matching unit, swr, power meter, or linear amplifier, the use of a short, flexible jumper cable is needed. These tend to have higher attenuation, the tradeoff being flexibility for signal loss. At lengths of 3ft to 6ft the attenuation is negligible. ===RG-58===CB and jumper for ham radio. Lossy.===LMR-240, 200 and 195===Because LMR-400 is thick and can put a lot of stress on the connectors of equipment, thinner more flexible alternatives are preferred for jumper use. LMR-195 is thin and flexible. RFC195 is LMR-195 equivalent and suitable for jumpers on 2m and 70cm application in lengths of 6ft or less. LMR-195 has less attenuation than does RG-58U at all frequencies. At CB frequencies it is 1.8 vs 2.5 and at 70cm ham it is 4.8 vs 7.4. LMR-195 has lower loss than other RG ‘58’ type cables. This is achieved through the use of a high velocity dielectric and a bonded aluminum tape outer conductor.
