Is the 20' DX Flagpole Right for You?

The Greyline Advantage: Smart, Strong & Elegant

Smart Design: At its heart is a highly efficient Vertical Dipole system. This balanced design is naturally quieter than other verticals, allowing you to hear weaker signals. Its low angle of radiation focuses your power on the horizon for true DX punch. Bonus: NVIS patterns are an important bonus for our emergency communications customers that require regional traffic, not just DX.
Strong Engineering: We use only premium T6061 aircraft-grade aluminum and stainless steel hardware. With a 110 MPH wind rating, this antenna is a permanent, reliable fixture, engineered to survive the elements and provide peace of mind. Pro Tip: Take the flag down for far higher wind ratings.
Elegant Appearance: This is an antenna your entire family can be proud of. Its clean, single-radiator design—with no unsightly traps or coils—blends beautifully into any landscape. It’s a statement of quality that earns compliments, not complaints.

73 Greyline Performance

20' HOA Antenna - Great Product

Excellent antenna. Made significant DX contacts over the past nine months. Straight forward installation with very good support from Greyline.

Quality Workmanship

I submitted a very positive review on the performance of my 20" flagpole but neglected to mention the high quality of the machining on the pieces and hardware. The pieces went together like a hand and glove.
Really appreciate the fine workmanship.

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.

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…..

Proudly displaying "Old Glory" and working the world!

At the age of 79 was able to install the 20ft flagpole antenna without help, which surprised me. I installed solar lights above and below the flag and it's a beautiful sight at night. I attached the ladder line directly to the ground and long wire terminals on the MFJ tuner and it works perfectly. Very low SWR on all bands. In spite of poor band conditions I have been having a blast. Frankly, it tickles me to have my antenna sticking up in my front yard in plain site. My neighbors love it and the HOA is clueless. 73's, Kelly K4SLE

4’ Extension Review

The 4’ extension arrived in a reasonable amount of time. Construction was excellent and assembled easily with my existing 24’ flagpole antenna. I have noticed improvement in reception and signal reports on the air, and look forward to continued experimenting on the air with this addition to my station.

20ft flagpole

Looks tremendous with Uk flag and works superb Highly recommended

Preliminary Review of 24' Flagpole Antenna

I purchased the 24' flagpole antenna with 4' extension added later. The materials and construction are very good. Parts fit together very well. Antenna aside, this is a handsome flagpole with flag.
I had no expectations for 160 meters. I purchased the antenna to supplement my EFLW antennas for 40 and 80 meters. Initially all tuned well from 10 - 40 meters using an LDG RT-100 remote tuner, but unable to tune on 80 meters. I upgraded to a Chameleon CHA-URT-1500 1.5 KW remote tuner, but still unable to resonate on 80 meters. I added a Palomar 4:1 balun between the remote tuner and the antenna and now am able to tune antenna well on both 40 and 80 meters.
I have had impressive domestic and DX contacts on 10-40 meters so far. I am hoping that with a little more effort, I can eventually get DXCC on both 40 an 80 meters. Will keep you updated.
