Hi
Many contesters are also Lowband DX'ers so I feel this may be a good
place to find people with the relevant experience to provide some
answers.
I am considering some receive only antennas for 80/160M. I have a 1
acre plot which is roughly square. This translates to about 200ft
square. I may be able to run a beveridge outside my property into some
rough ground such that I could manage a 1.5 to 2 wavelength beveridge on
80M.
It would be convenient to use the existing boundary fence posts to
support some 10ft canes and run the beveridge along the fence line. The
fence wire would of course run parallel to the beveridge wire and about
6ft underneath it. The fence wire is nominally "floating" i.e. not
deliberately earthed.
Question 1 - Would this wreck the beveridge performance?
Question 2 - My plot slopes downward quite a bit from North to South,
should I keep the beveridge wire parallel to the ground or should I keep
it horizontal?
Question 3 - Is there any meaningful way I can model a beveridge on a
sloping site (using Eznec).
Question 4 - For domestic reasons I don't want to run a beveridge
diagonally from corner to corner, this means I could only manage
0,90,180,270 degrees as the alignment directions. I have a feeling that
is not the best directions -any comments?
If beveridges are not practical has anyone any other suggestions? What
about EWE antennas, do they really work? I tried one when I was in
Coventry and can't say it was ever any better than my 80M dipole for DX.
Apologies if this is seen as off-topic.
