mAT-50 Automatic Antenna Tuner for longwire (outdoor mounting)

mAT-50 uses a number of advanced control technology, is currently the highest level of control technology antenna tuner. mAT-50 consists of two parts: tuner and coupler. Tuner are outdoor parts for tuning antennas. The coupler is an indoor part which is used to connect the transceiver, provide power for the tuner and control the tuner for tuning. There is only one 50 ohm RF coaxial cable between the tuner and the coupler. There are two versions of the coupler, the YAESU version and the ICOM&KENWOOD version, which are used to connect YAESU and ICOM&KENWOOD transceivers, respectively.

mAT-50 uses "No-Control-Line" technology and "Power-Off-Hold" technology. No-Control -Line technology can transmit RF power signal, control signaling and DC power on coaxial cable. The tuner does not need to be connected to a control line alone, making the tuner easy to install and use. Power-Off-Hold technology is that the tuner is powered only in tuning, and the coupler interrupts the tuner's DC after tuning. This technology enables mAT-50 to have more stable performance and excellent anti-interference capability.

It will tune dipoles, verticals, Yagis,Long-wire,Whip or virtually any coax-fed antenna. It will match an amazing range of antenna and impedances, far greater than some other tuners you may have considered, including the built-in tuners on many radios.
