This is the antenna that gets you back to the pure joy of radio—maximum performance, with minimum fuss.

The 20' HF Vertical Antenna is the definitive choice for the modern operator who demands efficiency and reliability. Built for those who prioritize a powerful signal over neighborhood politics, this antenna delivers world-class performance without the back-breaking work of installing a radial system. It's the smarter way to get on the air and be heard.

Is the 20' HF Vertical Dipole Your Perfect Antenna?

This antenna was designed for you if:

  • ✅ You want to get on the air without the hassle and expense of installing a massive radial field.

  • ✅ You are a new ham looking for a simple, all-band antenna that "just works" right out of the box.

  • ✅ You are a serious DXer who needs a low-noise, low-angle signal to break through pileups.

  • ✅ You operate from a small lot or location where a Yagi or large wire antenna is not practical. Docks, Rooftops, etc.

  • ✅ You value superior, American-made engineering and an antenna built for a lifetime of use.

The Greyline Advantage: Smart, Strong & Elegant

  • Smart Design: This is a true, balanced Vertical Dipole system. You'll hear weak signals that are lost in the noise on other verticals. The low angle of radiation is your secret weapon for working long-haul DX.

  • Strong Engineering: We use premium T6061 aircraft-grade aluminum and stainless steel hardware. With a 110+ MPH wind rating, this is a commercial-grade antenna designed to be the reliable heart of your station for decades to come.

  • Elegant Appearance: Performance doesn't have to be ugly. The sleek, minimalist design of our verticals has a professional, no-nonsense look. It’s a clean and effective radiator with no unsightly traps or coils to fail. Seamless elegance.

"The quietest vertical I have ever used. I'm pulling weak DX stations out of the noise with ease. A truly game-changing antenna." - Actual Customer Quote

IMPRESSIVE IMPROVEMENT

This is an antenna I wish I would have purchased sooner. We live in an HOA with a small lot and some restrictions on antenna placement and height. We had a small vertical antenna mounted to our fence, but had limited places to install grounds and could only put two in place along the fence line. We could only receive 40M, sometimes 20M, and both had to be tuned and adjusted at the antenna. This year, those bands began generating high SWR. I was able to determine the wiring and connections were all good but the antenna was failing and we would miss out on the new solar cycle. We ordered a 20' Greyline, without the flag mount options, along with an LDG 100W external tuner. Due to a backlog in supplies, it took many months to process my order, and when I paid with a credit card it was cancelled the following month because they could not ship it within 30 days to process my credit card. I called and they no longer had any 20' antenna packages to ship at that time, but they agreed to ship me a 24' for the same price without further delay. That was still not going to be visible from the street above my home which is an HOA requirement, so I agreed. After receiving the equipment and installing it, I was amazed. 40M, 20M, 12M, and 10M bands were all below 1.5 SWR. 30M was an impressive 1.1 SWR. Unfortunately, I could not tune 80M, 17M, or 15M due to high SWR. Quite possibly this is an issue with the LDG tuner. We have reached far away with this antenna, and my wife began using FT8 and collected QSOs with 29 countries on multiple bands within a week. I was able to reach Australia, which showed a distance of 10,000 miles. The antenna is in my back yard, close to my house and neighbors say they don't notice it. While I could have installed it in the front as a flagpole, I would have to re-rout all of my wiring to the front of the house. This is an impressive antenna. If I were to do this again, I would like to have purchased an already assembled ladder-line to PL-259 adaptor as assembling the provided kit proved somewhat challenging without a drill press which I no longer have after downsizing a few years ago, and having to modify the clamshell case so that it would fit over the PL-259 component. The RF-choke required weather proofing so I ended up purchasing 1-1/2" waterproofed shrink tube that seemed expensive for the length needed. In the end, it all worked well when connected. I fully recommend this antenna.

Wow! So great to hear that you and the XYL both are enjoying the bands together. Let's get those other bands working. Likely a ground issue we can resolve. *We've already called him for a few testing exercises to get things dialed in. Ham Radio is fun again! Pass it on... 73 Greyline Performance

After 3-months, impressive performance, SWR 1.8:1 on 75M-6M, busting pile-ups, & surprisingly...

Hi Jon at Greyline!

After using the Greyline 20’ OCV for several months I wanted to tell you how happy I am with its performance!

With a little tweaking of the installation, I now have matches of no greater than 1.8 to 1, 75M thru 6M. (using the LDG RT-100)

Even with the poor band conditions, we are currently experiencing, I have worked some nice DX….Albania, Peru, Ecuador Brazil, Italy, Spain and most other European countries with great reports on 100 watts from the TS-890. Nothing too exotic yet but I have not really worked at it either.

In short, if I can hear them, I can work them even through some serious pileups.

I am particularly impressed (and surprised) with 6M performance. I have had good reports as far as OK and ME. Really looking forward to improving conditions as the next sunspot cycle ramps up!

Thanks for the great customer support and info!

73, Craig W3GF

PS. I forgot to mention that my noise level is also several S-units lower than with my former 1/4 wave trap vertical which makes a real difference!
