Greyline Performance is pleased to offer SGC Smartuner HF ATU remote tuners.

SGC is Made in the USA, Smart, Strong, and Elegant. Truly high-end and rugged. The robust tuning range is worth a look and they are waterproof HF ATU's as well.

Tunes a mobile 7' whip from 160/80-6M.

Very popular with the marine industry for the isolated RF and DC grounds allow for less RF or common mode current at the radio. These outstanding remote antenna tuners can tune a wet noodle without breaking a sweat. The RF and electrical ground are solid. Tuners are generally hard to get wrong. That said, the quality of the inner workings are rated for power and are NOT the lower-end, cost-effective focused tuners we see in all the magazines. Radio ops that desire the very best quality available and Made in America buy SGC.

You want quality, this is it. They are military-grade, Made in the USA, marine industry-rated, autotuners, and are highly recommended for use with Greyline HF vertical antennas, and stealth HOA Flagpole Antennas. Built to last. 

 

SG-237 Smartuner™


RUGGED CONSTRUCTION  

Built to Last

The SG-237 is designed with high-density surface mount components on a 4 layer PCB, providing high efficiency, reliability, and performance. The PCB is mounted on a sturdy chassis plate which provides an excellent electrical and RF ground system. The unit is fully waterproof (under 2 ft of water for 24 hours). The case is weather-resistant, high-grade ABS plastic that is sealed at the factory.

MULTIPLE APPLICATIONS  

Use for base, mobile, portable, marine, or aviation.

The SG-237 is our most popular Smartuner. Its rugged construction and small size allow maximum flexibility. It has a 100W power rating and additional frequency coverage to 60MHz, matching it perfectly with the most popular HF transceivers. It will work with any balanced or unbalanced antenna including whips, backstays, dipoles, loops, and long wires, and requires a minimum of only 28 feet of antenna for full coverage operation.

Pro Tip: Add the DC/DC Coaxial Line Isolator
to remote control the SGC RF tuning unit over your feedline coax. That means, no extra control cabling other than your coax to the antenna site.
