Default How to use a simple SWR meter and what it means to your VHF

SWR in itself is not necessarily bad. Power reflected back toward the
transmitter is not lost as a result of the reflection itself. When
that reflected power hits the transmitter it is re-reflected back up
to the antenna.


And where it is reflected back into the cable again. And this continues
until the power is completely dissipated in by the losses in the path.

So a 3:1 swr with 6.25 watts of reflected power and 25 watts of
forward power, still delivers 25 watts to the antenna to be radiated.
That is of course when there is no feed line loss.


No. Power that is reflected the first time, will be reflected the secon time
it 'hits' the antenna. It wil NEVER be radiated.
