WebApr 16, 2024 · West Central Michigan. Nov 30, 2012. #2. Most high power transceivers have "fold-back" circuitry build in to reduce output power and porotect the final output transistirs in the presence of high SWR. Not something you really need in a legal or well build CB radio. I'm sure it's not cost effective for manufacturers to include such circuitry.

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.

WebThough rare, a defective or broken antenna can be the cause of high SWR problems and poor performance. Luckily, testing an antenna is a fairly easy process. If you're not familiar with the concept of resistance or how to measure it, please refer to our guide on Understanding Electrical Resistance before proceeding further. Step 1: WebDec 9, 2015 · SWR results when the reflected power interacts with the forward power to create standing waves in the transmission line. These standing waves have a voltage …
