Multi-band antenna.
The schematic.

This antenna utilises a commercial automatic antenna tuner. Rather than having the heavy tuner mounted up high, I used home-made open wire feedline from the elevated feedpoint of a 34 metre doublet to a much lower mounted antenna tuner.

The feedline to tuner connection.

The feedline conducors are separated and fed to the rf output and rf ground terminations. The incoming coaxial cable and power supply leads are looped through a toriod several turns, to help minimise rf currents returning to the transceiver.

The feedline is supported by a piece of electrical conduit mounted on the fascia to keep the feedline away from the metal gutter.
