Ameritron ATR-20 Antenna Tuners are versatile, high-power antenna tuners. The ATR-20’s roller inductor “T” matching network continuously tunes all frequencies from 1.8 through 30 MHz. They also feature a built-in 3-kilowatt peak or average directional power meter. ATR-20s have convenient connectors for coaxial and wire feed lines. A heavy duty, high-voltage insulated, current-type balun allows use with balanced feed lines.
Properly tuned, these ATR-20 tuners safely operate on all bands with RF power levels of 1.2 kilowatts SSB and 600 watts CW. They will handle load impedances from 25-800 ohms. Their matching range also extends from one ohm to 2500 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 six-position antenna selector switch allows selection of 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 tuner’s matching network in line) or “direct” (no matching circuit) configurations.
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.
