Uwe,
I have looked at your web site and can see the loop antenna but I would like
to
know how you match it to coax or a pre-amp. Can you help?
Your antenna farm looks good, my 18m long antenna will fit into a small space
in your garden.

Hi Mike es all,
yes I can help.
pse look up Peters site:
www.qsl.net/df3lp/137kHz/rx-loop.html.
the simple pre-amp works vy good, no IMs. instead of the power supply via coax
I do use an accu.
matching the loop by inserting a wire of 3/4 to 1/2 length of the loop round
(find the 50 ohm point by try and error) proposed on this reflector did not
satisfy: the sensitivity has gone (but the nulls were some what sharper).
regards
Uwe/dj8wx
