40m Delta Loop

John Corby

Finally got some mild weather in southern Ontario today so I put up an antenna I've been waiting to try out. It is a vertically polarized Delta loop for 40m. It uses 137ft of wire supported on a 30ft pole at the peak with the low, horizontal section just 4ft above ground. EZNEC modeling showed promising expectations so I was excited to test it outside as a possible RaDAR antenna.

I fired off some CW CQs at 5 watts using my Hendricks PFR3 radio and received an immediate spot on RBN from a station in Wisconsin 400 miles away. My signal was reported at a very strong 21dB so this antenna may be doing its job! Unfortunately I didn't get any QSOs but that has become all too common the way the bands have been lately.

Now I'm looking forward to a new RaDAR operating season with some new antenna designs. Hope to catch you all on the bands this summer.
