Coaxial Cable-Still The Best Way To Make An RF Connection

摘要

As its name implies, hard line is coax that isn't flexible like regular coax cable. It's essentially a pipe within a pipe whose outer conductor can be up to several inches in diameter. Keep in mind that hard line isn't waveguide, though. It truly is coax cable, but it's designed for high power and low loss at UHF and low microwave frequencies. It is widely used for radio and TV broadcast antenna feeds and cellular basestations.
