"I'm extremely happy with the SG-237 PCB that I use with success on my ex-army landrover, to tune a 5meter whip. When properly connected and grounded it tune my whip in a split second on all HAM bands up to 80M!" - Michel Vaerewijck ON7NA

"I have an SG-230 coupler and SG-303 antenna on the rear roof of my Yukon XL. This combination works better than anything I have ever used in my 30 years as a ham operator. I use it from 160M thru 10M with unbelievable results only running 100 watts. Thanks for a great coupler and antenna." - Bo Henderson KD4TL

"My third SGC tuner has been operating flawlessly for onver three years in New York City. It has survived a difficult environment, and was essential to 9-11 communications. Thank you for building such great products!" - Bill Thiele W2BWL

"I experimented with my SG-237 today. What can I say? Wow!!! It tuned up an 8ft aluminum pole and I made overseas contacts in Algeria, West Romania, Greece and Poland on my FT897. " - Mark Rabel
