Uwe,
Have a look at Bill Ashlock's website. http://bill.have-my.info/ he has two
good loop papers that can help you build a very good transmit/receive loop. Many
guys in the US have these loops. They work very well. I have 2 big loops in my
backyard.

Hi all,
I designed a LF loop - 8m high - 11,30m long -
2,5m over the soil - four
parallel windings - 3mm insulated Litze (thus
length is 155m). It looks
like an
extra large one-layer-coil (pitch: 14
to 15cm).
O.k. It functioned. But the vertical (12m high with elevated
coil and three
horizontal lines - two 70m long and one 30m - workes
better. The signs, which
roar over here from VO and from W, were on the
average stronger (2 to 5dB).
I changed the construction of the loop:
The condenser was removed. An
end of the
loop wire is directly, the
other one over a toroid coil grounded. The coil
consists of 15 windings. I
found the Z50 Ohm point at the third winding
of this
coil (counted from
earth connection).
With this construction I am very content. It works
as well as and sometimes
better than the vertical one.
But what is
it? It works nondirectionally, thus no KAZ. Is it a mini
Beverage?
Samuel help! I do not know, what I
did.
Regards
Uwe/dj8wx
