LDG Electronics AT-100ProII Automatic Antenna Tuners AT-100PROII

Additional Information

LDG Electronics AT-100ProII Antenna Tuners are the next step in the evolution of the automatic tuner. These desktop tuners cover all frequencies from 1.8 to 54 MHz and will automatically match your antenna in no time.

These tuners feature a 2-position antenna switch, allowing you to switch instantly between two antennas. Updated features include an LED indicator for antenna selection and an LED to indicate when in bypass.

AT-100ProII tuners require just 1 watt for operation, but will handle up to 125 watts, making them suitable for everything from QRP to a typical 100 watt transceiver. These tuners include 2,000 memories for each antenna; automatically storing tuning configurations for each frequency and band as you use them.

Frequency-sensing circuitry lets the AT-100ProII tuners "know" your operating band and frequency. Whenever you transmit on or near a frequency you've used before, AT-100ProII tuners can retune from memory almost instantly.

Rugged and easy-to-read LED bar graphs show power and SWR, and a function key on the front panel allows you to access a data-like mode and status.
AT-100ProII tuners use latching relays, which retain the tuned configuration indefinitely, even when powered down. They use LDG's state-of-the-art, processor-controlled Switched-L tuning network. They will match dipoles, verticals, inverted Vs, or virtually any coax-fed antenna.

Features include:

* 1 to 125 watt power range (SSB and CW), 100W on 6M
* Tuning time 0.5 to 6 seconds full tune, 0.25 sec memory
* Selectable user parameters: auto/semi, 125/12.5 watt scale, auto-tuning threshold, and more
* Tunes 6 to 1,000 ohm loads (16 to 150 on 6M)
* Optional external balun allows tuning random-length, long wire or ladder line fed antennas
* Includes DC power cable
* Power requirements: 11 to 16V DC at 500 mA maximum
