Hey OM:
A 3:1 mismatch you only lose 25% of the power. And that's power not
voltage.


Where does the 3:1 SWR come from? With the off-the-shelf $2 300:75 ohm
balun, connected to a 50 ohm feeder, the mismatch will be only 1.5:1.


A 3:1 swr does not really equate to a 25% power loss. I think it was the
ARRL that published a chart that at first glance may make it look like
that.
