What kind of coaxial cable do I need for operation on 2 meters or higher frequencies?
The output stage of your radio and most modern transceivers will require that you attach 50 ohm type coaxial cable (also shortened to the word “coax”), between the radio “antenna” connector and the antenna. This is the main and only “pipeline” for getting the rf energy that your radio produces to the antenna where it is radiated over the air. This “link” in your total antenna system is probably second in importance of station equipment. Remember that your antenna should be considered the first most important, then the coax. If these two combined parts of your station are poor, so will be your signal over the air and received signals will be weaker or not heard at all compared to a good antenna system. All of the components and devices between the antenna connector on the radio up to and including the antenna is called your antenna system. The idea of having a good low loss antenna system which consists of the antenna and it’s feedline (the coax), and an efficient antenna, will certainl
