LDG Electronics Z-100A Automatic Antenna Tuners

LDG Electronics Z-100A Automatic Antenna Tuners feature LDG's famous 10:1 SWR tuning range that matches Dipoles, Verticals, End-Fed wires, G5RVs or even Off Center Fed dipoles and Windham antennas. Easy integration with dozens of modern transceivers means plug and play operation could not be simpler. The updated compact and lightweight Z-100A tuner goes anywhere with any HF radio… desktop, portable, parks, islands or tall summits.

The Z-100A Automatic Antenna Tuner works with all HF radios up to 125 watts RF output and can be interfaced with dozens of modern transceivers. But, an interface cable isn't required for semi-automatic operation. Whether or not the Z-100A tuner is interfaced with the transceiver, it has an internal frequency counter and 2000 memories to store each operating frequency with antenna tuning parameters. Memory retuning occurs in only 100 milliseconds, with the initial full tuning cycle requiring an average of only 6 seconds.

Included with the Z-100A is the IC-104 DC power cable, as well as the three foot IC-100 Icom interface cable. Optional interface cables are available for Yaesu, Kenwood and Alinco. Here is a partial listing of transceiver series' listed Interface Cables and how they function:
