Description
mAT-705plus Antenna Tuner
The mAT-705plus is an automatic antenna tuner intended for use with the Icom IC-705 transceivers. The tuner is connected to the transceiver with an included data cable.
The mAT-705plus has a range of 1.8 MHz to 54 MHz. The maximum acceptable transmit power is based to the IC-705. It can tune virtually any coax-fed antenna. Use the HF kits ATU Choke BalUn to use the mAT-705plus for a symmetrical antenna.
The antenna tuner has a wide tuning range, much larger than some other tuners, including the built-in tuners on many radios.
Operation
The mAT-705plus is controlled from the transceiver. The tuner contains two Lithium-ion batteries, so it does not require an external power supply. The mAT-705plus is equipped with a USB-C plug and can be charged with any USB-C charger. the tuner uses a bi-stable relay so the batteries last a long time.
The mAT-705plus has 16,000 frequency memories. When you tune to or near a previously tuned frequency, the mAT-705plus uses “Memory Tune” to recall the previous tuning parameters in a fraction of a second. If no memory is available, the tuner performs a full tuning cycle and stores the parameters for recall from memory on subsequent tuning cycles on that frequency. In this way, the mAT-705plus “learns” as it is used and, over time, quickly adapts to previously used frequencies.
The transceiver’s included control cable is approximately 1 meter long.
