SGC Smartuner SG-231 is a microprocessor controlled automatic antenna coupler that gives you the most out of every watt of HF-SSB power. The SG-231 is a slim design that will easily fit in the most compact installations and is waterproof, making it perfect for outdoor use. The SG-231 can be used with a wide variety of antennas, including end-fed wires, center-fed dipoles, inverted “L”s, loops, mobile whips, and vee beams. With its typical tuning time of less than 4 seconds, the SG-231 is one of the fastest couplers on the market, able to re-tune in less than 10 milliseconds. The SG-231 also features non-volatile memory, so it will remember the settings for your favorite antennas even after the power has been turned off.
