Is feedline same as transmission line

WebThe feed line (also called the transmission line) is the RF power conduit between your radio and your antenna. All the energy you generate travels to the antenna through the feed line. By the same token, all the signals picked up by your antenna must reach your radio … WebDec 30, 2024 · Additional discontinuities in the feed line can increase the SWR seen on the feed side. These could be caused by a bad joint or using a section of cable or plug/socket of a different characteristic impedance to the rest of the system. Dec 5, 2024. #4.

Why does ladder line generally have a lower loss than coaxial cable?

In a radio antenna, the feed line (feedline), or feeder, is the cable or other transmission line that connects the antenna with the radio transmitter or receiver. In a transmitting antenna, it feeds the radio frequency (RF) current from the transmitter to the antenna, where it is radiated as radio waves. In a receiving antenna it transfers the tiny RF voltage induced in the antenna by the radio wav… WebPay Range. Pay Range $66,300.00 - $102,000.00 - $137,700.00.

WebMay 29, 2024 · Yes, the S W R can change along the transmission line. This is the case if the line is lossy. The S W R is constant along the transmission line if the line is, or may be … WebNow we can calculate the feedline loss: − 10 log ( L 1 − Γ 2 1 − L 2 Γ 2) = 1.02 d B Even assuming no tuner losses, this 450 ohm ladder line has 1 dB more loss than LMR-400. So indeed, in the particular example given, the ladder line does have lower loss than LMR-400, even without matching the load to the line.
