Hi Lee,

I'm a little confused about the bandwidth that you're getting. Maybe it
can be attributed to losses which widen the SWR bandwidth. That's not
necessarily a bad thing. I have used an AEA IsoLoop antenna that is
about the same size as your loop antenna but has a low loss butterfly
capacitor for tuning 10-30 MHz. On 20 meters the bandwidth is only about
20 or 30KHz(can't remember exactly since I haven't used it for a couple
of years). It works great if you park yourself on a frequency but it is
a pain to use for hunt and pounce.

Yes, of course that should have read 2.5 : 1 SWR which is better than my
`loaded` half size G5RV on 80 at about 100kcs 2.5 : 1 SWR.......

Besides the null using vertical polarization, is it possible that for
your local friend you may have been cross-polarized. Usually direct wave
cross-polarization is on the order 20db which accounts for the 2 to 3 S
units of change from vertical to horizontal.

My `friend has a quarter wave vertical for 20 and the loop was physically
vertical ....also, my G5RV is sloping......

Have fun with your new toy!

Thanks, i am...... ;-)
