For applications which call for extraordinary reliability, the Hustler HD Series of antennas are recommended. The HD Series antennas are suitable for use in the most difficult environments, remote locations, or tall tower installations. 
HD Series antennas are available with 7/8" E.I.A. flange connectors with pressurization option. Dual antenna versions of the HD antenna are also available upon request. HD Series antennas are available for applications from 136 MHz.to 2 
GHz. 

ELECTRICAL 
Our Offset Radiator (O.S.R.) design features phased 1/2 wave copper radiators which yield precise radiation angle control and very wide bandwidth. All O.S.R. materials are made of copper to minimize the possibility of intermodulation. Heavy 
duty radiating elements and feed system allows a maximum power of 400 watts. Lightning protection is provided by a brass lightning prong at the top, which is connected to a 0.2" diameter copper tube running the length of the antenna for 
grounding to your support structure. 

MECHANICAL 
A 1.9" diameter white extruded fiberglass radome is combined with at 2' long heavy wall (0.225") aluminum base. This structural combination provides stable vertical rigidity even in high winds. Wind survival is at least 130 mph. 
Weatherproofing is accomplished through the use of a sealed type N female connector. Removable drain plugs and O-rings allow proper drainage of internal condensation whether in the upright or inverted position.

MOUNTING 
Professional quality galvanized steel mounting clamps are provided. The rigid design of the clamps prevent ratcheting or twisting of the antenna in high winds. The clams accept mounting pipes from 1.5" to 3.25" in diameter, or angle 
members up to 2.5" per side
