Antenna Tuner Model 229

Reversible "L" circuit, silver-plated roller inductor, high-voltage variable capacitor and switch-selectable fixed capacitors for precision matching.

Automatically provides low Q, minimum-loss path.

Rated 2 kW PEP, 1 kW cw.

Matches 50-ohm unbalanced output to balanced or unbalanced loads (dipoles, inverted "V"s, long wires, windoms, beams, rhombics, whips, Zepps, Hertz, and similar) from 1.8 - 30 MHz.

Built-in balun.

SWR bridge indicates 1:1 to 5:1.

2-range power meter reads 10 to 2000 watts.

Front panel by-pass switch and 4-position antenna selector switch.

Coax and screw-type connectors.

Requires 12 Vdc for dial lighting.

Styled in black and bronze.

Front panel with black-out lighting.
