A new technique for feeding towers has been adopted for Amateur use from the
broadcast industry. You drop 3 heavy gauge wires connected at the top of
the tower to within a few feet of the bottom. Connect the three wires
together with a wire ring around the base of the tower and feed that ring,
connected to the three wires, with a simple L-Network with respect to your
Very effecient system. Several local DXers us it on 160m and 80m with great
results. One tower is 140' and the other I know is about 90' with a lot of
top loading from various beams....
You can Google this type of tower feed and get more information....
That describes the "folded unipole" vertical
