Default Why all the Fuss over a little SWR?

While I agree that many hams pay far too much attention to VSWR, there are
several other issues beyond loss in the transmission line.

Modern "barefoot" rigs, especially those without tuners, will throttle back
their output power (to minimize heating finals) when they see excess SWR.

Many amplifiers, designed for nominal 50-ohm loads, will not operate
efficiently into severely mismatched antenna systems.

We could go on and on.

So it all depends on what you consider "a little" SWR. I'm not concerned
with 2:1 or even 3:1 in some cases, but above that I break out the antenna
analyzer.

Looking at charts of cable loss due to SWR I note that any swr less than 8
or 9 to 1 results in hardly more than 1 dB of loss due to SWR using even
1/4" coax. So, really, why the FUD on this subject?
