HF SHIPBOARD WHIP ANTENNA RF-1930CHD FEATURES > Groundwave, LOS, and Skywave > Side feed allows convenient connection to Antenna Coupler > Fiberglass construction to prevent corrosion > Designed for shipboard applications The RF-1930CHD HF shipboard whip antenna is ideally suited for military shipboard use, as well as for fixed stations. Consisting of a two- section, 24-foot (7.3-m), heavyduty, military-grade fiberglass whip antenna; it has a power rating of 1 kW over the entire 1.6 to 30 MHz spectrum. It is supported by an integral mounting flange. 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. The antenna provides low-angle gain in the vertical plane and omnidirection in the horizontal plane; the radiated energy is vertically polarized. The antenna tuner feeds the antenna by a side termination band with a 1/4 -20 threaded stud. > Lightweight compared to many similar shipboard antennas harris.com SPECIFICATIONS FOR: RF-1930CHD ELECTRICAL SPECIFICATIONS Height 7.3m Frequency Range 1.6 to 30 MHz (with antenna coupler) Upper section 2.84-m (solid fiberglass with polyester laminate) Impedance Compatible with RF-382A and RF-2601/AC Antenna Coupler Lower section 4.11-m (tubular fiberglass with military grade epoxy) Weight 3.4 kg (7.5 lbs) VSWR In accordance with RF-382A and RF-2601/AC Antenna Coupler specifications Color White Gain See radiation patterns below Polarization Vertical Base Flashover 20,000 volts (wet) Power Rating 1000 W.
