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

The 28' HF Vertical Antenna (our 2" OD model) 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 28' 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 100 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
