Collection: SGC Remote Antenna Tuners | ATU

SGC World from Seattle, WA., apparently has gone out of business, quietly. They stopped answering their phones in May of 2023. Jon, KL2A immediately traveled to Seattle to knock on their door and try to buy any leftover products for you as we all enjoyed their stuff, but there was no storefront at the address. Sadly, we are losing quality manufacturers and products from natural causes and supply chain woes that continue to plague the tech industries that rely on overseas suppliers. RIP SGC!

SGC produces high-quality automatic remote antenna tuners that are reliable on every frequency, 160-6M. SGC is military-grade, made in the USA, rugged, and popular with Emergency Communication service agencies, ham radio, marine, mobile, aircraft, aerospace, and your security. Your new favorite antenna tuner. It pairs easily with Greyline HF vertical antennas and stealth HOA Flagpole Antennas and all radio brands on the market.

The SGC Remote Tuners are indeed strong, smart, and elegant. Using ABS plastic enclosures that are sealed-waterproof to protect the outdoor tuning unit offers you more options at your installation. With this tuner and any single antenna, your radio will find continuous coverage from 1.8 to 30 MHz and all HF frequencies in between. The unit is built to last and is backed by SGC's standard 1-year warranty and industry-leading technical service. Ham Radio is fun again.

Pro Tip: Look at the recommended power rating limits for digital modes especially and impedance range for tuning capability. Also, note the sheer number of memories of each unit plus the quality of the case itself.

I am providing my first impression report regarding my 24FT HOA antenna. Installation was easy once I was able to figure out the instructions. The twin lead spacers were missing so I inserted a section of PVC into the lower section to insulate the twin lead. I’m using an IC7300, MFJ 993brt remote tuner, Balun Design, Inc model 117t balun which takes coax as input and twin lead as output. I then feed it through an Array Solutions model AS309H arrestor which takes twin lead as both input and output. With the remote tuner: SWR readings are 1.2 in the cw portion of 40 meters and 1.5 in the ssb portion SWR readings are 1.1 all the way across 20 meters (my favorite band) SWR readings are 1.2 in the cw portion of 15 meters and 1.4 in the ssb portion I am a cw guy and have worked all over Europe and South America as well as New Zealand and am getting very good signal reports. Needless to say, I am very pleased with this antenna so far. It works way better than I expected I haven’t yet had to operate in windy or rainy conditions so there is more to learn.

Great pole, excellent service and communications.

I purchased the pole without the antenna and am very happy with the quality and ease of installation.

Great addition easy install

Added this to my 20ft flagpole for 160 m work. Able to make contacts, looking forward to up the power. Great flagpole!

DX and the Greyline antenna

What a wonderful Antenna I have made contacts in over 50 country's so far in less than three weeks easy to assemble and works.

24' Flagpole does the job.

I purchase a 20’ Flagpole antenna that also included the 4’ extension. I installed the flagpole the end of January here at my home in central Florida. The install was easy with only a couple of small issues that were easily resolved by just thinking things through. I installed the antenna in the back yard in the HOA and have not had any complaints.

The performance of the antenna has been very good. The SWR on most band has been =< 1.5 except the 12 meter band. The SWR is just under 2.0. The DX into Europe and Africa has been good. Have done a lot of FT4 and FT8 with good reports. SSB has been good with good signal reports depending on propagation. All of my contacts have been made on 70 – 100 watts. I am using a SGC 230 tuner mounted at the base of the antenna

Most of my contacts have been 10 MHz – 28 MHZ. I have done some work on 40 meters but not much. Not much of an night owl so I don’t get very much of a change to use the antenna on 40 – 160 meters. The SWR is on these bands is 1.0 – 1.3, so I would expect good performance if I had more power.

At this point in time the only negative I have to report is the flag. It has been flying on most days in 5 to 15 MPH winds. I have taken it down when we had higher winds had exceed the 15 MHP. I noticed this morning the flag was torn and shredded. I took the flag down and noticed the flag was made by Anley and it was manufactured in China. I wouldn’t expect a flag to be in this condition after 3 months. I had USA made flags last over a year flying in much stronger winds that this one.

I'm only giving a 4 because of the flag issue. I will reach out to Greyline to see what they have to say.

We are so glad to hear that your Antenna has FB SWRs from 160-10M and congrats on the great DX! Fun... We buy our flags from several USA companies one of which is Anley, Inc., which is also a US company based in California. We are happy to replace the flag.

US GOV reports 90-days is the expected Flag lifespan. 'The U.S. Government generally expects a nylon or cotton flag to last 90 days based on being flown daily from sunrise to sunset - but not during periods of inclement weather. Tests have shown that, in some cases, a flag flown 24 hours a day will last only one-fourth as long as one flown only during the daylight hours.' - again, happy to help and we will contact you directly for a replacement.

Remember, Ham Radio is fun again, Please pass it on to your friends and family. - 73m Greyline Performance
