Coax Cable Loss and the Impact of Bad SWR

Fred C (W6BSD)

Heliax Coaxial Cable The coaxial cable is critical when setting up a radio communication system. This cable transmits RF signals from the radio to the antenna. We use coax cables because they have a conductive shield surrounding the inner conductor. This shielding minimizes electromagnetic...
