OCF dipole ?? Not quite enough space to hang!!
 
Hi

I have a 260 OCF dipole that I wouldl like to hang but the largest span
between trees is about 220 ft. at about 60 ft high on one end and 80 ft on
the other.

1. How will the antenna performance be affected if I let the ends just drop
staright down?

2. The long side is 166 ft, short side 94 ft. - if letting the ends drop
down is OK, would it make a difference to put the vertical amount on one
side. If so, would it be best to let the extra drop vertically on the long
side? short side? or best to even up the extra on both ends?

Thanks in advance.

Ed,
Hang it and let both ends dangle 20 feet or so. Will it make
a difference? Sure, some, but 'how' is sort of debatable, and
probably not worth worrying about.

Idea: If you are not using it on 160m, make it 130 ft instead
of 260 ft.

You won't notice much difference on the lower bands. Since the
drooping ends will be an appreciable percentage of a wavelength
on the higher bands, you may notice some additional directivity.
