VK1AD Portable T-Match Antenna Tuner (ATU) mounted in a plastic case
L1 is tapped at turns: 1, 2, 3, 4, 6, 8, 10, 13, 16, 20, 26 and 37.
The vernier dials enable logging of each capacitor setting, which can be repeated at the next activation. This has so far proven sucesful for the 27.2 metre End Fed.

Each double-gang variable capacitor is isolated from the vernier dial by a plastic insulated 6 mm coupler. Rear gangs are in use.
