The high-performance notion, "if you can hear it you can work it" is widely reported. Add to this rugged engineering to be relied on for emergency prep, it will NOT fail when you need it most. See this YouTube video where the DX Flagpole Antenna faces a Tropical storm head-on. Look at those branches fly by at 70 mph+.

It has a bonus NVIS pattern that EmComm & EMS agencies value for passing important regional welfare & emergency traffic. During uncertain times. Survivalists, Preppers, Emergency Management Command Centers, & Disaster Communications Agencies such as MARS, ARES, Homeland, Coast Guard, FEMA, Red Cross & Ham Radio operators too rely on mission-critical HF antennas just like these for RF wireless networks.

We don't fluff our wind ratings. Safety first. We list these ratings conservatively allowing you more room for peace of mind & family security.

ALE capable antenna design offers Military and professional industries secure communications options with redundant, private RF networks for HFT, black box, to ham radio too using FT8, Winlink, WSPR, WSJT and SDR platforms, those that enjoy the frequency hopping capability, full duty-cycle, and high power design. No power limitations with Greyline Antennas.

Made in the USA (W7 region) We're honored to provide local employment and manufacturing training. We spend first on small ham radio owned businesses for specialty parts not manufactured in-house.

Ultra-premium materials are used throughout and custom RF antenna design for a true free-standing, No Radials, highly efficient, properly engineered vertical-dipole, broadcast-style radiator.

This is no ordinary HF radio antenna, these stealthy high-performance antenna systems deliver a low loss, surprisingly low noise, reliable NVIS pattern, an always low angle transmit and receive sensitivity that meets or beats antenna designs of similar height on the market today, all while serving you reliable communications and deeper DX experiences. How does this sound to you?

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 modern RF Tech 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 you 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 radio ops value this higher efficiency as the RF power is available at the antenna where it belongs. Add to this a surprising attribute, an NVIS pattern is reported from our agency clients. That is it 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 work the DX, right?

The professional industries enjoy the innate ALE aspect too. Frequency-hopping offers you instant band changes popular with digital mode ham operation, EOC & emergency communications services, HFT, and others requiring secure RF networks common with welfare and homeland security agencies.

The Image here showcases transmitted radiation patterns (angles) from 80-6M. A Horizontal antenna by comparison likely needs to be at 60-70' high to produce these angles on the lower bands. Notice there is no pattern breakup until 6M. A 43-foot vertical with radials won't produce this clean pattern across the bands.

Now you can work Real DX from home, office, or HOA, and look really good too. Your family will enjoy the compliments from the neighbors. Ham Radio is fun again. Pass it on.

Let's compare the Greyline 12-28' heights for radiation angle & gain "punch"

Here we compare each of our Vertical Dipole / Flagpole Antenna designs side by side for angle and depth of gain in telling graphical plots. Notice the low band improvement between the 20' and 28' but also notice the 12' and 16'ers holding their own on 80 and 40M too! A real win for those more restrictive HOA QTHs. Pro Tip: All are aesthetically approved by XYLs and can be dressed up nicely with flowers around the base. Hint. Hint.
