The Gold Standard




 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. RUGGED VERSATILITY

New “500 watt” Line Isolator with exceptional performance
A Smaller, better LINE ISOLATOR

Line Isolators are especially
effective in reducing RF current on the outer surface of a coaxial cable’s shield while having no effect on the signal carried within the cable. Current-type devices are singularly
well suited to this application, because of everal exceptional features that are not present in other balun designs. In the list of desirable characteristics is a very high
load isolation over a very wide bandwidth, extremely low loss characteristics and a wide, low SWR bandwidth.
