Antenna Tuner Model 229
Description
- 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.
