I've been "playing" with W7EL's EZNEC a lot (it's downright ADDICTIVE!-),
mostly comparing all-band wire antennas I might be able to construct.

I know how to have it calculate SWR for, say, 3.5-29.7 MHz, but that
results in a really-dense and hard-to-see chart. Is there a way to
have EZNEC calculate SWR for JUST certain hambands withOUT showing
the non-ham-band parts of the spectrum.

For example, 3.5-4 AND 7-7.3 AND 14.0-14.35 AND ...
but NOT including 4-7 OR 7.3-14 OR 14.35-21 OR ....
