Objet?: [TowerTalk] SWR is what SWR meter measures
I hate to sound stupid, but at that risk here goes.
When I was in school for psychology one course on IQ and testing said,
"IQ is what an IQ test measures." I have transliterated that into, "SWR
is what an SWR meter measures." There are some pretty basic designs to
measure SWR using diodes to detect voltages. There are also some more
sophisticated designs and instruments to measure SWR which yield
(relative) impedance.
But can I ask, "What is the difference in perception at the receive end
of a HF wireless signal transmitted with an antenna measured that has a
2:1 (impedance either high or low) SWR versus an antenna that has a
measured SWR of 1:1.2 or so - given you are working with the same
antenna AND given your modern rig does not power reduce prior to 2:1
SWR?"
I suspect the perception is negligible and that any efforts at reducing
SWR lower than 2:1 are futile, a waste of time, and fruitless other than
for personal satisfaction. Is this a correct observation or largely in
error?
Let the flames begin.
