I really enjoyed reading your information on the loop antenna. I found it interesting and very informative; I shall return again when I stroll down the lane of loop antennas as a trade off using my 817nd portable. I wont have time or space to through and hang a wire. Thanks again for your time and experience.

Hi Julian,
As always, an interesting read.
A suggestion for mag-loops you may not have considered. I generally use a 500+500pf air variable cap but connect the hot ends of the loop only to the stators and leave the frame floating.
This doubles the working voltage while halving the capacity. In addition, since the wiping contact carries no current, the wiper is no longer of any concern.
I've tried faraday loop feeds and never found them to be great. My personal preference is for a simple Gamma arm between the base of the loop (current node) and the 'sweet spot'. Sweet spot is found by trial and error.... tune for best match, adjust arm position for lowest reflested power, then repeat a few more times to refine the position of sweet spot. Bash the tube flat, drill and pop-rivet into place. Crude but effective.
My last loop used the rim from an old damaged bicycle wheel (mine!) with a 500+500pf across the horns and a gamma match (10mm copper micro-bore) pop-rivetted into place. It works fine for such a small aerial. My first CQ call on 2.5W brought an immadiate reply.
I wish you all the best with your ongoing health concerns.
