Acom 04AT 1.2 kW remote tuner
Remote automatic tuner with 4-antenna switch, 1.8–30 and 50–54 MHz, 1200 W, for Acom amplifiers
The Acom 04AT is a remote automatic antenna tuner with a built-in four-output antenna switch. It covers continuously from 1.8 to 30 MHz and from 50 to 54 MHz and handles up to 1200 W.
Product description
It can be installed in the shack or remotely, even outdoors near the antennas: this shortens the feed lines and reduces losses. Only one coaxial cable is needed to the shack.
The switch selects one of the four antennas, assigned by the operator band by band. It is designed to work with Acom solid-state amplifiers, such as the 700S and 1200S.
Key features
Built-in switch, selection per band.
With antenna SWR up to 3:1.
Near the antennas, a single coax.
Compatibility and notes
Works only with Acom solid-state amplifiers (e.g. 700S and 1200S).
