 Icom AT-140 automatic antenna tuner

ICOM AT-140 Automatic Antenna Tuner

This antenna tuner has been designed as an upgraded version of the AT-130,
for use with MF/HF marine and HF commercial transceivers.

The design and specifications are similar to the AT-130, but the addition of a
tuner 'through' function, allows the transceiver to bypass the antenna tuner
when tuning cannot be completed.

Also, it is now not necessary to open the casing to arrange the wiring making
connection of the AT-140 to a transceiver much easier
