Colección: No-Radial HF Vertical Antennas 160-6M | Greyline Performance DXV

The Greyline HF Vertical Dipole Series

No Radials. Lower Ground Loss. Just Signal.

The Greyline HF Vertical Antenna is not a compromise. It is the result of a physicist’s answer to a DXer’s problem: how do you significantly reduce ground coupling — the single largest source of loss in a vertical antenna system? You eliminate the need for ground radials, entirely.

Our OCF Vertical Dipole Antenna (VDA) design feeds a high-aperture radiator in a balanced configuration — the antenna works against itself, not against a buried radial field. The result is a quieter noise floor, lower losses, and a smaller physical footprint than any radial-dependent system.

Choose Your Vertical

Five core sizes from 12 ft through 28 ft — each covering 160 meters through 6 meters. No tuning required at the antenna. No pruning. No radials. Add an ATU at the base or in the shack for seamless transceiver matching and you are on the air in under an hour.

• 12 ft DXV — Entry-level full-band coverage. Apartment rooftop, small lot, or portable base mount. Wind-rated to 155 MPH (ASCE 7-10).
• 16 ft DXV — More aperture is more signal. The EmComm team’s first step up from portable. Wind-rated to 115 MPH.
• 20 ft DXV — Core performer. Small yard, suburban rooftop, or rapid-deploy EOC installation. Wind-rated to 90 MPH.
• 24 ft DXV — EmComm standard. Embassy-class performance. Chosen by HOA ops & agencies requiring permanent, high-reliability HF infrastructure. Wind-rated to 70 MPH.
• 28 ft DXV — Maximum aperture. EOC-grade. The highest-gain configuration in the Greyline VDA line. Wind-rated to 55 MPH. Guy support recommended above 24 ft in high-wind environments.

The 5/8 Wave Gain Engine

Pair any DXV with our 9-ft Adjustable DX Whip to hit the 5/8λ sweet spot on your target bands. Field-tested gain: up to +3.5 dBi at the horizon. That is the effective equivalent of doubling your transmitter power — without touching your radio, your license class, or your power limit.

ATU Options: Remote or Shack — Both Work Real DX

Every Greyline DXV is designed to work with an automatic antenna tuner at either end of the coax. A remote ATU at the base — such as the LDG RT-100 (100W) — keeps the feedline at a matched 50Ω on every band and minimizes coax loss on longer runs. A desktop shack tuner behind LMR-400 or better is equally effective for most installations. See our Feedline Physics guide and ATU placement explainer for the full technical breakdown.
