Hi Tom,
Yes, BEAUTY!! ![]() No, not the stuff you step in, the stuff you have to shovel. Oh, wait. Both "S" words fit that description. I was working in Hayward on Friday and we were having a white-out from the "S" word. Hard to believe it was 80 just one week before Aurora. Actually, I'm quite pleased with the Quagi. It appears they outperform (most) Yagis (at least in gain) with equal numbers of elements. The loop driven element also seems to help with noise pickup too. It seems to be a quieter antenna than my Yagis. Running QRP on 432, I'll take and radiation I can get, even if it's from the feedline ![]() omni-direction part of my antenna so I can hear others calling and then I can swing the antenna!!)

I can live with that! It was only 0.3 dB below the reference antenna, an 11 element Yagi. Seems to have a very sharp pattern! Anybody have experience with this type antenna? I was impressed enough to think about giving the 222 version a try... Scott N0EDV Good to see you today, Scott. Finally a "nice day" for Aurora - 45 degrees, sunny, and 15 mph north winds. Much nicer than the last 2 years, eh? I have many 432 designs that will work better than a quagi on the same boomlength. The quagi as you made it has a significant amount of feedline radiation, and the gain could be a lot better. Drop me a note, and I can give you plans, including the T match. If you dont have delron element insulators available, there are cheap substitutes you can make from plastic wall anchors. And 222 yagis are available also. I have K1FO yagis scaled to all bands that are appropriate. tom K0TAR |
