Topband: Shielded Loop

[Bob Beebe]

I have been busy building receiving antennas here over the last two weeks and a couple of nights ago finalised my 160M set up for the weekend contest. Compared to my Beverages I have, which are relatively short, my new shielded loop built out of LDF550 really is working well. Signals are down about 10dB from the Inv-L and Beverages as well but the important difference here is that the signal to noise ratio is amazing. My very high noise level has dropped like a stone. I heard VQ9LA calling on Tuesday and heard no other EU's calling him and we made it 2nd call! Great, and another new one. I really took care of symetry on the loop which tunes well by an audio peak method but my analyser didn't offer much help. But if anyone is suffering serious noise problems a loop may be for you. I'll try and put some pics on my site when I get time.

See everyone at the weekend. SOHP
