Webper 100 feet, so one way to reduce line loss is to use less of it. Assuming the line is the shortest possible length, there are two ways to further reduce loss: Reduce the SWR, change to a lower-loss line, or both. You can reduce the SWR by adjusting the antenna. In the case of a wire dipole, this means either cutting wire or adding wire ... WebDec 21, 2016 · A feed line is a cable that feeds radio signals from a radio antenna to a transmitter or receiver. It connects the antenna to the receiver, transmitter or transceiver and is widely used in wireless communications and broadcasting antenna systems. It transfers the radio frequency energy between the antenna and the receiver.

Webthe feed line, the voltage seen (only the peak value is shown here) is a bit high on 80 meters, but it goes out of sight on 160. As expected, with open-wire feed line, the additional losses due to SWR remain remarkably low for SWR values up to 9:1. Only on 160, where the SWR climbs to almost 40:1, do the additional losses due to SWR become ...
