Description

The SB-230 HF omni-directional antenna is a broadband, vertically polarized antenna primarily designed for shipboard use, but can also be used as a fixed base station with a suitable ground screen. The antenna operates over the frequency band of 2 MHz to 30 MHz without the need of a tuner or coupler. It has a power handling capability of 1kW, average. The monopole is 35 feet long and is constructed in two sections, which screw together. The base of the monopole is a flanged coaxial design which bolts directly to the Antenna Base Unit.
