Thanks for your patience, steve, High noise level here and you faded out. Hope to catch you again soon.

You will John. I'm motivated to put up a better antenna. Before today, I hadn't made a contact on 15 meters in something like 20-25 years. Thanks.

The 40 meter delta loops do apparently have some directivity on 15 meters. I could hear it on many signals when switching the pattern. But according to the modeling, the take-off angle is way too high and the gain is nonexistent. I'm sure I can do better.

A simple extended double zepp will work well and give you about 3Dbd. i used on on 15 in the last cycle. Solong as you can get it a half wave high and broadside to me there will be no prblem, I'm sure.

Was considering just that, an EDZ. Another thought was a pair of dipoles stacked. The stacked dipoles provide more gain at a lower take-off angle and and with broader azimuthal beamwidth. I'll probably start off with just a dipole and go from there.
