Unlike a resonant dipole the pattern varies a lot depending on the
frequency.

A local here is about to put an offset center fed dipole up in the air. I
think this antenna claims to work 10-80m.  This is most likely going to be
in the 40-45ft high range at best. A couple of questions came to mind when
he mentioned that this was going to go up.

If one end is in a tree, the other off a tower or some other support
structure such as a tower, WHICH end would be in the tree..the SHORTER
section or the LONGER section.does it matter?..(should the short end be in
the tree or the long end?) .again, does it matter?

The manufacturer had recommended the antenna be installed FLAT and not as an
inverted vee. At the aforementioned height, should this make a difference?

At the aforementioned height, will the antenna have broadside properties or
more unidirectional? 

Start the flames.thanks for reading in any event.  - Mike
