EZNEC - is there an easy way... SWR... ham-bands only?
 

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 ....

Hi Myron

You've made me curious. Why do you not want to make as many VSWR charts
as you have "Bands" of interest?
You surely realize that you can record the VSWR curve of each band
individually then save them on all on one page somewhere in your computer.

I have learned things about antennas by recording (on one document) many
radiation patterns with the antenna height above ground changing slightly
between plots. When I scroll thru the plots it almost looks like a moving
picture.

I sure agree with you about the fun you can have with that EZNEC.

Look up "Frequency Sweep, Input File" in the EZNEC manual index.
