Compatible Transceivers
The Z-100A is designed to be used with any Icom 100-watt transceiver that supports the AH-
3 or AH-4 Icom antenna tuners. Currently, this includes:
IC-706
IC-718 (select AH-4)
IC-746
IC-7000
NOTE: If using with an IC-718 select AH-4 mode. See the IC-718 owner’s manual for details.
The radio interface cable supplied is 14” long. If the Z-100A is positioned farther from the
transceiver, a custom cable can be constructed. This can be accomplished in two ways: Cut
the supplied cable and solder a jumper wire between all the connections, or purchase new
connectors and cable to construct a custom-length interface cable from scratch.
The 4-pin AH-4 interface connector is Molex part number 03-09-2042, available from
several online component vendors, such as DigiKey
1
and Mouser
2
. The connector also
requires four pins, Molex part number 02-09-2103. The 6-pin Z-100A interface connector is
