The antenna consists of a broadband radiator and matching network hermetically sealed within a high strength epoxy-fiberglass radome.. The interior is foamed, thereby providing a shock resistant unit and preserving the watertight integrity even if the radome is punctured or incurs serious surface damage. Air transportation at high altitudes poses no problems with the foamed configuration.
The lower portion of the antenna consists of an aluminum base with three flexible ground radials for quick deployment.
A quick-clamp socket is used for attaching the antenna to a vertical pipe support on a tower. RF input is to a Type N receptacle located in the bottom of the base.
The unit is designed to handle input powers to 100 watts CW. It has a VSWR under 3.0:1 on50 ohms as measured at the input connector of the antenna. The antenna contains no ferrous materials or nonlinear junctions which result in the generation of electromagnetic interference even after extended field use.
Because of its inherent broadband characteristics and unique electrical design, this antenna is relatively insensitive to mounting location and the surrounding environment.
Antenna CA-3520 is designed to comply with Environmental, Shock and Vibration requirements of MIL-E-4158 for general purpose ground equipment.
