At 24 feet the antenna also runs ahead of a full-radial quarter-wave on several bands in NEC modeling over average ground, strongest on 12 and 10 meters, with real gain on 30, 20, 17 and 15. The Greyline is a vertical dipole: return current flows through the lower element, not a buried radial field, so frozen ground, rock and sand don't matter. Want It Taller? Add the Whip The 9' DX Whip seats right on top: 33 feet on the heavy-duty base, at about 90 mph in our engineering model. Pair it with the 3" HD Tilt-Up Base and walk it down when the forecast turns.
