LDG AT-100 PRO II – Automatic Antenna Tuner

$315.99

The LDG AT-100 PRO II covers 1.8-54 MHz and features a two-position antenna switch allowing instant switching between two antennas. It requires just 1 watt for operation but will handle up to 125 watts, making it suitable for everything from QRP to a typical 100-watt transceiver.

Description

Like most LDG tuners the AT-100 PRO II operates automatically, beginning a tuning cycle whenever the SWR exceeds a preset limit. It also features LDG’s advanced memory tuning, providing 2,000 memory locations; when tuning near a previously used frequency it will recall the settings for nearly instant tuning. It learns your favourite frequencies and bands as you use it.

It will match dipoles, verticals, inverted Vees or virtually any coax-fed antenna. With an optional LDG balun, you can also use long wires or antennas fed with a ladder line. It handles 100 watts SSB or 50 watts FM/Digital when used with a solid-state transceiver; vacuum tube transmitters cut the power ratings about in half.

Please Note: When used with radios like the IC-7300, FTDX10 or TS-890 in bypass mode the tuner will pass 70 MHz with minimal loss but will not tune at that frequency.
