![]() "LT" wrote in message ... 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...... ;-) Lee....G6ZSG...... 73 LT snip |
