"...I had been using this [SG-230]coupler for a couple of months now, which I am sure, must be 10 to 15 years old...  I work with many VU stations in south India in split mode and they are quite fascinated by the way this coupler works... All you have to do is call CQ three times and the coupler takes care of the rest. It seems I can say good bye to SWR as long as the coupler is fine and running, and hands free band to band hopping has become a reality for me. Thanks for the wonderful product." - Satyan Chennai VU3MES

"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

Ordered an SG-211 when first launched at Dayton and received 60 days later, "The delay was worth the wait. Excellent product!"

"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
