If there was a significant issue with coax radiation before placing the coax balun at the feedpoint, we would expect to see a high SWR when the amp was off also. The degree of mismatch would not change from great without the amp to terrible with it. WebGood SWR & Antenna Resonance. Standing Wave Ratio (SWR) is an important concept that describes how good of a match exists between a transceiver and antenna system. Recall that a perfect match corresponds to an SWR of 1.0, with higher values indicating some degree of mismatch.

WebCurmudgeonly_Old_Guy • 4 mo. ago. There are 3 basic factors which effect SWR, Transmission line, impedance match, antenna resonance. My understanding is that without transmission line, the impedance match of the antenna becomes much more important to actual signal output than resonance.

In most cases the lowest SWR will not be at the same frequency as the best performance. This is because we have optimized the antenna for performance first, SWR second. If the problem is with the driven element the SWR can be very high (over 3:1 and as high as 10:1). If the crystal view chemicals
