Experiment #2 1.45 meter loop made out of 7/8″ hardline donated by KH6IB.

I continue to get good reports using this antenna for PSK.

A test with Randy kh6ib showed I had to come down to 60 watts or so to transmit of 40m…   It’s odd that phone mode SSB created apparent arcing on the cap, or some kind of foldback, where psk did not – makes no sense to me yet.

Some A/B tests indicate that the transmit gain is down 5 db from the End Fed.  Other times, no difference.   On receive there have been many times the loop can operate when the EF cannot, probably due to high noise levels picked up by the EF.
