My WARC-7 worked fine on 12 & 17, however on 30 it had no front to back. By
placing a known signal source about 100 feet away from it and observing for
f/b, I found it was best at 9.5 MHz. Moved the shorting bars on the
reflector out 8" (shortened the reflector by a total of 32") it now shows
good f/b at 10.11 MHz, right where I want it.
Just point the antenna straight up to check SWR. As long as the reflector
is not touching the ground you will get good readings.
