High swr ham radio
WebAug 20, 2024 · A high SWR implies the load impedance is significantly different from 50 ohms, violating the design specifications of the amplifier. Yes, there is power reflected in a feedline. But it's not this power per se that causes problems, it's simply that the impedance seen by the transmitter isn't the 50 ohms it was designed for. WebLike weather frequencies, the Ham net frequencies also vary from state to state. For example, according to the ARRL Ham net’s directory, there’s a Bartlesville, Oklahoma rag …

WebJun 8, 2024 · Secondly, common mode current sourced from the feedpoint is power that is not going into the antenna, and may be radiating in directions we don't want and causing high swr. Other sources of common mode current should be negligible and inconsequential.

WebMay 7, 2016 · Transmitters sort of force you to do this by backing off the power when the SWR is high, meaning the load is not 50 ohms. Bypassing the "SWR foldback" and tuning for maximum output power is likely to cause efficiency … WebJan 21, 2024 · Tuning to minimize SWR might improve receiver performance by changing the efficiency of RF transfer near the frequency of interest compared with that of other frequency ranges where the SWR is higher. (e.g. some antenna tuner circuit configurations act as bandpass filters).
