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

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 ATUs as well.

A premium and preferred ATU pairing for the Greyline Antenna Systems.

Considered higher-end in quality, these ATUs are popular with various professional industries such as Marine, Aeronautical, and of course Amateur Radio operators too. One aspect to point out that sets it apart from other offerings on the market is the dual-ground protections. Its isolated RF and DC grounds allow for less RF or common mode current at the radio. Some might say then that it removes the need for RF Choking in addition.

These outstanding remote antenna tuners can tune a wet noodle without breaking a sweat. Well, so some have reported. The RF and electrical ground is solid. Tuners are generally hard to get wrong. The quality of the inner parts is a step up from the low-cost-focused remote tuners that we see in magazines. Radio ops that desire the very best quality remote auto tuners Made in America, look closer at 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.

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.

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
