Presenting to our peers an HOA, nationwide-approved, Stealth DX Flagpole (DXFP) and the DX Vertical Dipole (DXV) line of HF radio antennas that do NOT require radials.

We believe you'll love this useful service in the form of a smart, multi-band or all band ham radio antenna system that again, does NOT require radials! Choose from 12, 16, 20 and 28-foot vertical-dipoles, stealth (DXFP) or non-stealth (DXV). They all get out very well from 80-6M. Here's one customer's excitement:

"Got Indonesia (YB) this morning on 40m SSB with 100 watts. Just over 9,000 miles!"

That’s right, DX confidence is once again restored with one vertical antenna that operates across all bands with high-efficiency, using the highest quality materials, note that high-power is standard, producing lower angles than comparable and taller verticals requiring radials, proudly offering you very low losses throughout the antenna system and again, requires no radials. We've done the hard work so you simply plug in your coax and get on the air!

"Smart, Efficiently Designed and Ruggedly Engineered Radio Antenna System!"

We want to earn your trust by offering something more useful to our peers. Before you buy look closely at our performance measures and the various research writings of the science, our products, "their" products, all capture within our RF Blog and FAQ pages for your consideration on the validity of our seemingly bold claims.

"Holds its own vs. taller competitors with no radials & is also stealth!"

Throughout the website, we showcase clearly for you the many reasons why the “OCF” off-center-fed antenna design operates at greater than > 90% efficiently across the bands and is perfect for your situation. You could always buy a tower and put a yagi up there... or you could put up this pole and work the world with a clear DX confidence.

To be polite, it simply meets and beats most verticals with radials you'll find on the market today, even the taller antennas.

"Equal or better performance than taller verticals requiring radials!"

Again, these are not just wild claims. We have done the hard math and exhaustive research (head scratching) and present to you transparently a wealth of data for you to consider. We are asking you to challenge us and ultimately, help shape our story while we endeavor to bring you, our peers, a more useful service. 

"High power (1500W+) antenna and feed system are now standard!"

Introducing to you, our peer, the old meets new, OCF line of vertical antennas brought to you by Greyline Performance, RF Research. We think you and yours will be quite pleased with your new antenna.

RF Research

Let's look at the various comparison data to several antennas on the market today in line with our Greyline Performance Antenna Systems. A little Q&A is always fun, right?

 

Q. How does the Flagpole Antenna compare to other well-known antennas? 

A. Let's compare our 20 and 28' versions with the Hy-gain AV-680 and Cushcraft R9:

The Red inner rings are 80M, blue 40M, green 20M, and orange 10M. You get the idea.

Look at the low angle in the OCFs and that extra punch. Yep, no radials needed!. Sure, you can use radials, of course, but they are not required for this performance! 

 

Q. I hear 43-foot verticals with radials is a "sweet spot" but you guys promote a 20 and 28'er, what's the difference?



A. Bigger is not necessarily better! In this case, our DX Flagpole Antenna is less than half that height, does NOT need radials where the 43-foot vertical with radials option does. Also, our OCF antennas enjoy a lower angle of radiation on many bands. (see graphic) 

There's more. HOA's and CC&R's do not typically allow the 43' version but the 20' height is under most HOA height limits around the USA.

Now, look at the low bands! The DX Flagpole Antenna really shines compared to the radial dependent antennas, and yes, even the 43-foot vertical has the same limitations.

On the high bands, the radiation pattern really breaks up with that ground mounted radial required 43-footer! You won't see that break up with a proper install of our OCF design. 

How would you like to get back on the air with real DX confidence? Now you can have lower loss, lower angles and higher performance on all the bands with a DX Flagpole and/or the DXV OCF. Let's get you on the air and have some fun. You'll sound amazing.



Q. What's the difference between a 12' 16' 20' and 28' Flagpole?
A. We are surprised to find and report very little loss when dropping to the 16 and 12' foot designs. Those in those more restricted and height challenged locations can now enjoy a little more DX confidence on the bands! 

Look at the low band performance (40/80M) on the 12' version! 

 

       

 

FURTHER DESCRIPTION

This antenna is HOA approved because it’s a real flagpole, where other antennas look too unsightly to be considered. Not in an HOA, we have the DXV line of OCF vertical dipoles in non-flag versions.

Before you buy

Learn about why our OCF design proves high performance vs. many other comparable and taller antennas on the market today. We dig deeper to find the information we believe you will find useful in making a wise choice of antenna for our needs. Our RF Blog is a great place to gain further insight on topics. 

Compared to other antennas:

These HF radio antennas confidently outperform even the much taller, lossy, ground fed verticals that require radials and in most cases, unfortunately, come with the “birdcage” of unsightly matching stubs, traps, cross-bars, top-hats, coils, and the other stuff your neighbors and significant others do not appreciate. It matters, right?

Aesthetically pleasing and high performance:

Our off-center-fed vertical antennas display a clean aesthetically pleasing design that offers far more efficiency (QRP ops love this) as multi-band antennas, on all 10 bands than some monoband poles fed with coax! We share with you why this claim is even possible. It’s worth understanding. We offer a powder coating service too. Pick a color, add it to your cart. Now you’re making everyone happy!

Lower Loss, Lower Angle, High Efficiency:

These antennas offer you lower angles, lower loss, higher performance, further reach and a real DX confidence to make ham radio fun again on all bands! The larger 43’ vertical with radials has a hard time competing with even our smaller antennas. (You must see the data.)

Not your average antenna:

Please see our performance charts here and within the FAQs to learn why this is not your average HF Vertical antenna. To be clear, the OCF Vertical Dipole designs are a higher performance option in a shorter vertical owing to the design and feed system. Let’s make radio fun again and get you and your friends back on the air.

Let’s have some fun and get you back on the air with DX confidence. You’ll be glad you did. Your family and friends will appreciate the aesthetically pleasing demeanor as well.

Flagpole | OCF Vertical Dipole Backstory:

Many hams have asked for optimized antennas for multiple band operation, so we challenged antenna designer, QST author, and an inhabitant of a neighborhood where towers and Yagis would not go down well, John Portune, W6NBC, to come up with a compact vertical dipole which would be ATU "friendly" delivering good-to-excellent VSWR matches on all bands 80m through 6m with popular autotuners, in particular, the new breed of outdoor rated units. John delivered, in spades. John opted for an OCF design which makes it easier in most cases for ATUs to find a good match across a wide range of frequencies.

We didn't cut any corners! Tubing is aircraft grade 6063-T832 aluminum, 2-inch OD top to bottom (28' is 2.25" OD at the bottom), thick fiberglass insulators at the feed and base that are designed to handle the load, stainless hardware, Amphenol PL-259 connectors for the pigtail, and a custom built common mode choke 1:1 current balun.

We have tested the Greyline Performance Antenna Line with several ATUs and all worked excellent on all bands 80m through 6M. For similar results we urge the use of the OCF antennas with an outdoor ATU located at or near the base of the antenna to keep feedline losses to a minimum, however, this antenna will work with many indoor ATUs and even some rig ATUs (we have tested with the Flex-6700 ATU).

ATU Mounting Disclaimer: Again, we urge the position of the ATU at the base of the Flagpole and OCF antenna for best results. We can't guarantee performance across all bands when the antenna is used with indoor ATUs as the feedline between the ATU in the shack and the antenna is an impedance transformer itself which could cause a very high mismatch on one or more bands, plus many built-in rig ATUs have limited adjustment range. Again, we urge that the ATU must be mounted at the base for respectable performance results.

Below is a typical SWR chart from the field. Results vary with coax length and tuner position, of course. Expect a match and efficient radiation patterns.

Placing the ATU at the base of the antenna will maximize performance. There are many outstanding outdoor-rated ATUs that can be powered over coax.  If you are looking for a tuner, we see many models online starting at $250. Look for the weatherproof box option.

We recommend you are aware of the Federal radiation exposure regulations if your Antenna is near your residence or where people may gather. QRP operators love this antenna for its very high efficiency and yes, of course, you may choose to run full legal limit as the antenna system is designed to handle that and more.

Power Limitation: Please be aware the power limitation is based on your choice of feedline and Tuners rating. We provide you with a balun that will take the full legal limit of 1500W+ as standard.

Installation couldn't be easier. Three feet of PVC tubing (supplied) buried in "compacted" soil will be enough in most locations to support the antenna, just "drop it in." Of course, you're welcome to install in concrete, on your rooftop or deck or other locations.

Wind Rating: This antenna has been engineered to withstand 90 MPH wind gusts, according to “Guide Specifications for Design of Metal Flagpoles,” ANSI/NAAMM FP 1001-07. This was used rather than ANSI/TIA-222-G (regulating antennas and towers) as this standard will be the one needed by building committees for structural analysis.

Built Rugged yet with quick-deploy and portable sensibilities in mind, the DX Flagpole and non-flag OCF's are a solid option as an easy install for FT8, SDR, MARS, Emcomm, DXpedition, IOTA, Field Day, new hams, and those of us downsizing to HOA and so on; a wonderful all band antenna solution on one (1) pole!

Custom: We are developing more application-specific options so watch for those. If you're interested in taking your Vertical Dipole Antenna far from home or into the field please contact us about the possibilities.
