Well, that's a generous offer, JHR. I am tempted to take you up on it. Only
problem is that I plan on employing it on the same mast with the
transmitting antenna. Is that bad practice? The reason is that I am not
allowed an outdoor antenna, and I live in a small flat.
I would love to get something in the air, though. I am thinking about
building one myself according to Rick's Old Folk's type antenna, out of
coax and wire. Given my construction skills, it will be mickey mouse, but
(hopefully) electrically sound, and give me an idea of what these antennas
sound like.
Jupiter should be here tomorrow. I'm curious to see how it reacts to the
indoor antenna 4 meters from the operating position. I've ordered another rf
choke for the receiver to match the one at the antenna, and if necessary
will take additional steps.
Then, I'll think about the antenna. I've already started to look for a frame
for the loop - I'm thinking 3/4" pvc; and flexible copper tubing for the
main loop.
