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. So while you may experience high SWR due to a lack … WebWhether transmitting or receiving, a higher SWR correlates with a less efficient coupling of energy between the transceiver and antenna. This inefficiency is problematic when transmitting because it can make a lot of heat, and it limits one's ability to overcome noise at the intended receiver.

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 and distortion to suffer more often than not. In a similar manner, tuning for best efficiency or distortion would probably reduce ...

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.

WebIn our experience an SWR of 1.4:1 or less is normal. 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).

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. (See this article on SWR for more information.)

WebOct 7, 2015 · High SWR can reflect enough power back into the radio to create enough heat to cook the final RF transistor. It isn't usually an immediate failure, it takes some time for that heat to build up and do damage. Likely what is happening is that the radio is sensing the high reflected power and throttling back the power to prevent damage. WebThe term “SWR” means standing wave ratio. An “SWR” meter is used to measure how well the transmit power signal emitted from a transceiver (radio) is traveling through the …
