Would your Idea be practical Telamon considering the reverse voltage
capacitance of a varactor is limited to a small swing in PF? Maybe
lots of diodes in parallel?

Ack Ack, 12:59, back to work.

Well a couple of things come into play.

Local noise goes up, along with atmospheric, and loops tend to have
greater local noise rejection over a voltage type. This is especially
true for a shielded loop. There is no loop advantage in atmospheric
noise save for lightening storm noise so it might make a better summer
antenna.

The lower in frequency you go the signals tend to be directionally phase
stable and so with a loop receive pattern you can null signals.

The higher in frequency you go the less advantage there is in a loop
over a dipole but it will work just fine.

I think paralleling diodes to get more capacitance than what one diode
can provide will work. Can't think of a reason why it would not work.
