I barely had room for 102 ft G5RV which I installed about 30 ft high which
barely misses my 2 story house peak. Both ends are completely in the trees.
I did manage to drop the feedline perpendicular to the dipole and mostly
vertical running away from the line of the dipole.
It is fed through a Heath SA-2060 tuner.
Best simple wire antenna I ever had and I have 80-10m no problems.
It is also paralell to and about 30 ft from HT power line. Maybe that acts
as a reflector?
