Hi,

I am looking for a simple wire antenna for the 80m band (and for 40m also),
which will cover a range (radius) of about approx. 300 miles and has a more
or less 360 degrees radiation pattern. Also I have not very much time for
testing (a few hours only). Any good idea?

If I would hang up a full wave lenght horizontal loop for the 80m band,
which will be a 2 wave lenght horizontzal loop for the 40m band,
approx. 25ft (8m) over the ground only, some questions will rise up ..

a) would you expect a more or less 360 degrees radiation pattern,
because the loop is hanging at 1/10 resp. 1/5 of lambda about the
ground (a more or less "wet" meadow)?
b) which normal/typical working range (radius) would you expect during the
day 80m/40m? 100, 200, 300 or more miles?
c) which impedance would you expect at (80m/40m)?
d) which type of feeding line and matching method would you recommend?
e) any further comments and recommendations?
f) should I simply forget this idea? :-)

Please respond via e-mail (direct) and many thanks for your help in advance.

Big antennas, high in the sky, are better than small ones, low! [bah]

I use a full wave loop (Square) on 80/75m here in Australia and feed it in the corner with 75ohm coax, it's resonant on 3.770 with a 1:1 SWR, but I tune it slightly when I operate up or down the band. I have had a lot of success during Grey line to work all over the world in the DX window. I have worked Europe, SE Asia & China, Russia, Scandinavia, USA, Canada, Alaska, Central America, South America, Southern & Northern Africa.
My loop is tilted to about 45% and faces North East down a valley to improve the lobe directions, rather than sending the signal into the sky as a cloud warmer.

So I'm interested to know how things are going for you on your antenna.

I guess you realize you are responding to post from 18 years ago.

Yeah, sad to say but all *real* antenna discussion
