Ameritron ATR-30 Antenna Tuner

Ameritron ATR-30 Antenna Tuners are high-powered manual antenna tuners

Ameritron ATR-30 Antenna Tuners are high-powered manual antenna tuners with a roller inductor "T" matching network that continuously tunes all frequencies from 1.8 through 30 MHz. They also feature a built-in 3-kilowatt peak or average detecting directional power meter.

Ameritron ATR-30s have rear panel connectors for coaxial and wire feedlines. A heavy-duty, high-voltage, insulated current-type balun allows for their use with balanced feedlines.

When properly operated, ATR-30 tuners safely function on all bands with RF power levels (CW or SSB) of 3 kilowatts with load impedances from 35-500 ohms. The matching range also extends from one ohm to 2,500 ohms (5 ohms to 500 ohms on 160 meters) at slightly reduced power ratings.

Peak and average forward power, reflected power, and SWR are displayed on an illuminated cross-needle meter. An internal 6-position antenna selector switch selects three coaxial line outputs or a single-wire line balanced line output. Two coaxial line outputs, ANTENNA 1 and 2, are available in either "tuned" (with the tuner's matching network inline) or "direct" (no matching circuit) configurations. The coaxial output port ANTENNA 3 is available only as a direct (no matching system) configuration. Wire/balanced line positions are available only as "tuned" configurations.
