I hear all the horror stories of verticals or inverted L's next to a tree
but have to agree with Eddy, VE3CUI, VE3XZ. A tree should be better than a
metal pole or tower. I have a diagram of the K8UR/W9LT vertical dipoles at
KC1XX and they work fine with a tower in the center.
At my QTH I have a pair of old Mor-Gain 80/40 dipoles that are mostly
vertical in tall trees. The first one went up just before the D68C
operation 20 years ago and when they called for 4's I was the first through
on 75 SSB. This one is attached to a high branch and runs between two
trees. The bottom half slopes slightly NE. I mounted a second in my
backyard that is mostly vertical with the bottom half sloping slightly to
the W. I have an 80 half square (bi-directional N/S) and the vertical
dipoles get me through well toward Eu and AF or ZL/VK. However, I agree
with KR2Q that my Cushcraft 2 el 40 is better (by as much as 2 or 3 S units)
when I use the Mor-Gains on 40. No metter which way the beam is pointed and
it does have about 12 to 15 DB front to back.
I remember the ham from North Carolina who liked quarter wave slopers but
found that over North GA clay and Stone Mountain rock those same antennas
did not work at all.
I do think that the vertical wire needs to be several feet away from the
