Quick Overview

Smart Tuner


  • The SG-230 Smartuner was the first product in the HF market to offer fast, flexible tuning without any user interface. The Smartuner senses RF when you transmit from your transceiver and automatically finds the best SWR match to your antenna. This unit works with ANY radio and ANY antenna and requires NO special interface, making it the most versatile tuning product available. The SG-230 can be used in base station, mobile, marine and aviation applications - and has been the "Gold Standard" of automatic antenna tuning for more than a decade.

A Wise Investment

  • The SG-230 is built in a rugged ABS plastic enclosure which is sealed to protect it, and allows ultimate versatility in installation. With this tuner and any single antenna, you will have continuous coverage from 1.8 to 30MHz and it can be used with any transceiver you'll ever own. The unit is built to last, with the highest quality components and backed by SGC's standard 1 year warranty and industry leading technical service.
