"160-6M with the 16' DX Flagpole and SGC-237 Remote Tuner! Excellent solution for HOA community ham radio operation."

CUSTOMER SPOTLIGHT: KJ7CWQ

Old meets new is pretty cool. Vintage Ham Radio.

This 16’ flagpole antenna is of very good quality and was easy to assemble. I chose to do a concrete foundation and when that was done it was up in no time. Propagation has not been good, but I have made contacts on 40 meters to the Pacific Northwest with my longest to Hawaii (I live near Phoenix, AZ). I am looking forward to better performance when the bands open this winter.

The antenna is 30’ from my shack and I am feeding it with LMR-400 into an SG-237 coupler at the base of the antenna. My rig is a Yaesu FT-991a.

SWR’s: 160m 2.0, 80m 1.75, 40m 1.5, 30m 1.25, 20m 17m 1.10, 15m 1.25, 12m 1.0, 10m 1.5, 6m 1.5.

In my community, we are restricted to flagpoles no taller than the peak of your house and they must be 10’ from the property lines. Other than that no permission required to install it. Now that it is up I had our community manager check it out and he thinks I can go a few feet taller. I ordered the 4’ extension kit from Greyline Performance so we will see if that increases the performance a bit. Too bad we can’t post pictures here.

Take a look at the 16' DX Flagpole Antenna "excellent for your HOA ham radio operation." and consider ordering one for your front yard too. It will work just like his, guaranteed that Ham Radio is fun again!

WHAT CUSTOMERS ARE SAYING:

"Real DX 160-6M at my HOA"
"4 Band DXCC in 3-months at my HOA."
"So pretty my XYL approves!"
"If I can hear it, I can work it."

Let's get you and your friends back on the air. Ham Radio is fun again!

Fun Plus

Looks great and works even better. I hear more stations on my regular nets than I normally do. I used stone papers for a rectangular wall around the flagpole which matches the house. A beautiful, wonderful, addition to my hoa property.

A positive upgrade...

I was impressed with the quality of the antenna tubing used. It's not the normal aluminum used by the other manufacturers, but a precision machined tubing. It fit together tightly with the thick fiberglass insulating sections. Using the LDG-RT600 remote antenna tuner, it tuned very well on 40-6 (I don't use 160/80) as a ground-mounted 28 ft. vertical dipole and really captures the DX! My QSO and country count really started accelerating from where it was. I live on a small corner lot with no HOA, and have no real trees for antenna supports. I can now reach AUS and the South Pacific with ease from the East Coast of the USA. I had a special installation so it took me about 5 hours to install by myself (several trips to several hardware stores for clamps, all-thread and such). It was pretty much a 'remove and replace' with the old antenna. All-in-all, it was a worthwhile investment and upgrade, I love this thing!

Very pleased and impressed.

I got HOA approval, even though they require white fiberglass flag poles. I explained that while it was a genuine flag pole, it was also an amateur radio antenna that provided emergency communications if needed. Living in hurricane country, that thought that was a very good thing to have in the hood.
As for the technical details of the antenna, speaking as one who has built their own flag pole antenna, this one is a great design and manufactured antenna. The machined parts and hardware are first rate! The performance is superb. I’m FT8 ing points easily 1000+ miles on 20w. (20 meters).

I’ve tried to include photos, but can’t seem to…..

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.
