I use a similar approach. I have a very strong Kevlar line strung
between two tall trees and the dipoles are at least 40 feet from either
tree. My dipoles at 60 feet out perform my beam at 30 feet by a
substantial margin.

I have been playing with the two-tree solution to the one tree problem,
with a family of inverted Vees (and a K3 and KX3, for keeping this on
topic). The "one tree problem" is that a Vee hoisted onto a top limb of a
coniferous tree is inevitably too close to if not tangled into the
branches below the apex. So, I've been selecting two of the tallest
candidates a couple of hundred feet apart and stringing a stout nylon rope
between them. In the middle of the cord I attach the balun for the Vees,
thereby allowing the legs to be in the clear, moveable from side to side,
and tied to smaller (8') trees at their distal ends. In one variation on
the theme I had a 40 meter dipole as the center section of the supporting
rope, tied to the same balun as an 80 meter vee. In another I tried a
linear-loaded 80-meter Vee, about 45' on a leg; it loaded fine but didn't
perform as well as the full length version.
The surrounding forest is very likely still a problem, but that's life in
the woods.

I have run a double Zepp hung from the trees as you suggest. If you can
do it I would get the antenna across the tops of the trees. 45' is too
low for 80M unless you are running NVIS in which case you are too high at
45'. Keep in mind that pine trees are parasitic so keep the wire, even if
insulated, away from the trees. Inverted V works if you can't maintain
60'.

I realize this is another somewhat not on topic post, but it is in
regards to my KX1 and KX3. I have a mature pine forest; 60 -70 foot
trees. How compromised would an EDZ be hung 45 feet up about four rows
of trees in from the perimeter? No branches or needles inside the forest
until 50 feet up. Richard KD0NPM
