5:1? Why even bother running an amp if your SWR is that high. That's a lot
of reflected power back into the shack and on your feedline.
I know a guy that runs an amp with a huge antenna mismatch and guys that
hear me at 100w with a properly tuned antenna can't hear him for crap. He
isn't making efficient use of his power. Run all the power you want, but
there is no substitute for a good antenna to connect to it.
