It covers 1.8-54 MHz, and features a two-position antenna switch allowing instant switching between two antennas. The AT-100ProII 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.\u003c\/div\u003e\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\u003cdiv\u003eLike most LDG tuners the AT-100ProII operates automatically, beginning a tuning cycle whenever the SWR exceeds a preset limit. The AT-100ProII 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 favorite frequencies and bands as you use it. You can also start a tuning cycle manually whenever necessary.\u003c\/div\u003e\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\u003cdiv\u003eLarge, easy-to-read LED bar-graphs show forward and reverse power in peak or average mode, and SWR. Two power scales are provided: 12.5 watts and 125 watts. The bar-graphs also indicate tuner status and input confirmations.\u003c\/div\u003e\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\u003cdiv\u003eThe AT-100ProII uses LDG's state-of-the-art, processor-controlled Switched-L tuning network. 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 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.\u003c\/div\u003e\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\u003cdiv\u003eThe AT-100ProII uses latching relays which retain the tuned configuration indefinitely even when the unit is powered down. The latching relays also enable extremely low power consumption; when not actively tuning the AT-100ProII draws next to no power at all. This makes it suitable for portable or mobile operation from batteries.\u003c\/div\u003e\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cb\u003eSpecifications:\u003c\/b\u003e\u003c\/div\u003e\u003cdiv\u003e* Transmit Power Limits: SSB: 1.0 to 125 watts; CW: 100 watts; FT-8: 75 watts; PSK and Other Digital Modes: 50 watts; 6 meters: 50 watts.\u003c\/div\u003e\u003cdiv\u003e* Latching relays for ultra-low power operation.\u003c\/div\u003e\u003cdiv\u003e* 4,000 memories for instantaneous band changing.\u003c\/div\u003e\u003cdiv\u003e* Built-in 2-port antenna switch, with 2,000 memories each.\u003c\/div\u003e\u003cdiv\u003e* Tuning time 0.2 to 5 seconds full tune, 0.2 seconds memory tune.\u003c\/div\u003e\u003cdiv\u003e* 1.8 to 54.0 MHz coverage.
