I use a single tall tower, 127' tall, and two 25' high wooden poles. Each
wooden pole is 450' from the tower. Each end of the 80m dipole ais attached
to Phillystran cable which runs to the wooden pole. It is pulled tight
enough to reduce the sag to negligibility. The centre of the antenna is
attached at the 120' level (the top guying point). The ends droop down to
about 100' on each end. That leaves the average height at 110'. The dipole
is not perfectly horizontal, but it is much closer to a true horizontal
dipole than to a typical inverted vee configuration.
