Tunes with SSB. Just pick up the Mic and start talking!
The AT-100Pro is full featured, frequency sensing, memory autotuner designed for
today’s HF radios. It features a built-in two-position antenna switch with over 2000
memories for each antenna. Latching relays reduce power consumption and hold
the match even with DC power removed. The Function key allows multiple uses
of front panel buttons for mode, status and other user definable parameters.
The tuner uses LDG’s standard high efficiency, microprocessor controlled,
switched "L" network to work with Dipoles, Verticals, Inverted Vees and other
coax fed antennas. Use the optional 4:1 or 1:1 external balun for long wires or
ladder line fed antennas.
