My home-brew 1kW Z-match in situ

The most versatile & easy to use antenna tuner I know of is the Z-match. Two motors drive two capacitors across a fixed inductance. Tunes 160m through 6m (seriously, it does). Controls are in the house: two 2pdt center-off toggle switches & a 12VDC supply. (The box on the wall is the motor-driven shunt capacitor that tunes the 30ft tower on 75m.)
