Pocket Antenna Tuner

Boris Popov, UN7CI

This article is described a small (almost pocket) Antenna Tuner that can work with 100- Watt transceiver.

The antenna tuner is a small version of the legendary "Ultimate Transmatch" introduced by Lew McCoy, W1ICP. However at the Lew McCoy's transmatch is used a roller inductor and all capacitors are variable ones. It is very nice for matching but it is not real for pocket design. At this version the roller inductor changed to tapped one and a coupling variable capacitor changed to row of the fixed ones. Figure 1 shows schematic of the tuner.
