WebAbout losses...think in dB. An S-unit is about 5-6 dB (okay, this is an estimate for signal levels above about S-5/6, calibration varies with radio - what a mess of inconsistency :-) ). Yes, total loss (TX or RX) is the sum of many things...cable loss, SWR mismatch loss, tuner loss, connector loss, switches, power meters, poor workmanship. WebWatts the reflected power would be 1 Watt. So a return loss of 20dB indicates a reasonably good match. For those that want to think in terms of VSWR, a 20 dB return loss is equivalent to about a 1.2:1 VSWR., suffice to say the bigger the value of the Return Loss the better is the match, and the less power is being “lost” to reflections.
