LDG IT100 ATU
Automatic antenna tuner for Icom transceivers
The problem: Icom's AT-180 ATU matches an SWR of only 3:1 at most (2.5:1 on 6 meters)! This limits you to antennas that are pretty much resonant to start with; droopy dipoles and wet-noodle verticals on Field Day are out of the question with the AT-180. And, the AT-180 has only 70 memories.
Once again, LDG comes to the rescue. The IT-100 is the ideal tuner for your shiny new IC-7000. First, it matches up to 10:1 SWR (3:1 on 6 meters), so just about anything you can feed with coax is good to go. And, it has 2,000 (not a typo; that's 2,000!) memories, enough for every Dxpedition, RTTY spot and radio buddy you've got, and then some. Just hit the tune button on the radio, and your IT-100 will set tuner parameters in less than a second if you've been there before. If not, it kicks off a full tuning cycle that will be over in about 3 seconds. Don't need the tuner just now? Then just tap the Tune button briefly, and the tuner goes into bypass. Press it again to bring the tuner back on line -- it's that simple.
The IT-100 is just 6.5" long, 6.5" deep and 1.5" tall. It weighs only 1.5 pounds, and gets its DC power directly from the radio; no separate power supply needed. The IT-100 works with any Icom radio that supports AH-3 or AH-4 Icom antennas.
This currently includes the IC-7000, IC-706MkIIG, IC-718, IC-746 and IC-756ProIII and others.
