The Right Tuner. At the Right Place. On Every Band.
The Greyline VDA is a wideband antenna — it radiates on everything from 160 through 6 meters from a single feedpoint. That's the whole point. But covering that range means varying impedance at the feedpoint across bands, and we need an ATU along the way to fine-tune to your favorite bands.
Remote mounting matters. A remote tuner at the feedpoint eliminates feedline loss entirely. One coax run. Clean match on every band. No drama.
Both remote and shack-based ATUs are popular with amateur and professional operators alike — and both are widely used for Real DX with Greyline Antennas. If you already have a quality shack tuner with sufficient impedance range, it will likely tune a Greyline VDA on most bands.
The LDG RT-100 is our recommended match for all DX Flagpole and DX Vertical systems at the 100W level. Weatherproof enclosure. DC powered over the coax — no separate power cable to the antenna. 2,000 memory locations that learn your operating habits. Band changes in 0.1 seconds on previously used frequencies.
Running an amplifier or sustained digital? Consider searching HRO for ATUs in your desired power range at HRO. We like ACOM, 4O3A.com, and Palstar (Made in USA).
Build the antenna. Plug in the coax. Tune up. Work the bands.
