The RF-1930CHD antenna provides gain and near-instantaneous bandwidth performance over the 1.6 to 30 MHz spectrum when used with an antenna tuner (RF-382A or RF-2601/AC). The unique fiberglass composite construction is designed to withstand the rigors of a military naval environment. The radiating elements are embedded within fiberglass to prevent corrosion. The anodized aluminum mounting flange is 6-inches in diameter. Four 5/16-inch bolts holes are equally spaced around a 5-inch diameter bolt circle.
