Legacy Balanced Antenna Tuner
The balanced tuner described in this article has two front-panel adjustments, a turns counter that turns two roller inductors that is connected together with two pulleys and a timing belt and a high voltage capacitor

L Network Tuner
The L-Network tuner is a simple impedance matching network that consists of one variable inductor and one variable capacitor

Motorized L-Network Antenna Tuning
I needed a remote antenna coupler that would match the antenna on any frequency from 1.8 to 29.7 MHz including oddball military frequencies

Remote ATU
For the variable capacity, I choose an arithmetic progression of capacity with 8 relays, starting from xx pF up to yy pF for the highest capacity. The four smallest capacitors are made of short sections of RG-174/U coaxial cable
