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. It’s 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 longwires, and requires a minimum of only 28 feet of antenna for full coverage operation.
