Used SGC-231 SMARTUNER

This used example has been mounted indoors so is in excellent condition and is fully functional

SGC Smartuner, The SG-231 Antenna Coupler is designed to match any random length of wire from 2.4m or longer in the frequency range 3.5 to 60MHz, and 7m and upwards in the range 1 to 60MHz. It is capable of handling 100W (PEP), 50W maximum on CW. It is thus ideal for a wide range of commercial applications including marine and military use and by radio hams around the world who need a simple system that is easy to use on a wide range of frequencies. Only four connections are required: transceiver input, antenna wire, earth connection and 13.6V DC. The SG-231 with its microprocessor control automatically selects inductance/capacitance combinations to achieve a perfect match as soon as RF is fed to it.
