Bigger vertical antennas are NOT better!
We stacked the Greyline HF Vertical Antenna with no radials vs. the Mighty 43' Vertical with radials:
Key: *80M-red | 40M-blue | 20M-green | 15M-orange
Notice the 12' vertical antenna holds its own on 80M. The 16-foot works 160M many radio operators report to us. (see FAQs)
The 20-24-28' has even lower angle and a stronger punch for deeper DX performance.
The NVIS pattern is an added bonus to our Disaster & Emergency Communication Services clients. Regional welfare traffic handlers such as FEMA, MARS and ARES folks alike enjoy the added security and the elegance of a good looking Flagpole Antenna.
FT8 operators love this antenna for its frequency hopping ability (ALE) to operate from 160-6M limited only to the speed of your antenna tuner. Remote radio stations really enjoy this one. It's 2021 afterall. What can you do with a real antenna for all bands?

DX Flagpole Antenna vs. legacy vertical antennas
We have fond memories of the legacy brands over the decades so it made sense to us to look closer at them. Here we compare the Cushcraft R9 and Hy-Gain AV-680 along side our 20 and 28' DX Flagpole and DX Vertical Antennas using Professional antenna modeling software.
The R9 and AV-680 do have a pretty pattern and they are similar in height to our Greyline Antennas, at 25-30' tall.
The R9 and AV-680 are often bristling with lossy and unsightly stubs, traps, loading coils, and capacitive hats. That doesn't help gain approval with the ladies, family, or the likes of your neighbors. They aren't HOA approved either, not without a dose of deception and that's simply, uncomfortable. [Hint: our Flagpole is built to Federal Flagpole Statutes, it's a real Flagpole.]
No-Radials: So, you're looking for a Real DX antenna for 160-6M, would like approval from the XYL and HOA and don't want to lay down 100+ radials to achieve high performance, right? Consider smarter, stronger and more elegant for your QTH. Your family and neighborhood will thank you!
Pro Tip: Before you buy, understand why we focus on efficiency. Less-loss in dB's on both transmit and receive are considered to equal higher performance. Every dB counts! We have your covered. Learn more in our FAQs.

>90% efficiency with a 20' DX Flagpole Antenna
Using modern Professional antenna design software and 30+ years of professional antenna design experiences, we have calculated this Antenna System's efficiency at greater than >90% when an antenna tuner is installed near the feed point.
Here's an example for you. The low power and low noise ops such as QRP and FT8 raido ops just love and need this higher efficiency as the RF power is available at the antenna where it belongs. That's low noise. Add to this a surprising attribute, an NVIS pattern is reported from our agency clients that supports a strong regional efficiency on transmitted and received signals. It's a vertical dipole, lower noise. In emergencies, this is priceless. You have to hear it, to complete the RF network or work the DX, right?
Professional industry enjoys the innate ALE component too, a frequency-hopping agility that allows instant band to band changes. Popular with the digital mode ham operators, emergency communications services, and secure RF network requirements of many welfare and security agencies too.
The Image here showcases radiation patterns (angles) from 80-6M. Notice there is no real pattern breakup until 6M. A 43-foot vertical with radials does look this clean.
Now you can work Real DX from home or HOA and you'll look good too. Your family will enjoy the compliments from the neighbors. Ham Radio is fun again. Pass it on.
DESIGN + ENGINEERING
Made in the USA using premium-only materials down to the last detail. Aircraft grade aluminum, double-walled for strength and aesthetics. Industrial-strength fiberglass insulators at the feed and base, low profile stainless hardware throughout, a high-power feed system, RF Chokes, all plug and play to your radio station. The default ground install is well received and the robust engineering lends confidence to other options such as a tilt-mount, bulk heads, roof top installs, tower mounts, and sailboats too. Where will you install yours?
Our wind ratings are rock solid and conservative offering you even more security. We focus on Smarter, Stronger & more Elegant, an extra-strength approach that adheres to Federal statutes, “Guide Specifications for Design of Metal Flagpoles,” ANSI/NAAMM FP 1001-07.
Need HOA Approval? Remember, this is a Real Flagpole.
The most discerning high-end neighborhoods and loved ones will be proud of your aesthetically pleasing Flagpole. You will receive compliments. Of course, your log will be full of the DX experiences, the kind you only dream of. But don't take our word for it, see what others are saying, here.
HOAs & the most discerning XYLs, family and neighbors will compliment how good it looks.
"4 Band DXCC this summer with my DX Flagpole!" says one happy op. "My wife loves how it looks, thank you!" Ham Radio is fun again!
