  • Power Handling: 100 W Average

Detailed Description

The Valcom VGP 30-88 AM and FM antenna provides omni-directional, vertically polarized coverage with 2 dBi minimum azimuth gain throughout the 30-88 MHz frequency band. Designed to handle power levels up to 100 Watts CW, it exhibits an input VSWR of less than 3:1 as measured at the N type input connector located at the bottom of the base. The antenna is influenced relatively little by its mounting location and surrounding environment due to the inherent broadband characteristic of the electrical design.

A broadband radiating element and matching network are hermetically sealed inside the antenna's high strength epoxy fibreglass radome. The interior is foamed for shock resistance and to preserve the watertight integrity against radome puncture and serious surface damage. An aluminum base and three flexible and quickly deployable ground radials make up the lower portion of the antenna. Designed for installation at a ground station, the quick clamp socket accepts a two inch pipe mast for mounting at the top of a support tower.

The antenna is designed to comply with the environmental, shock and vibration requirements of military specification MIL-E-4158 for general purpose ground equipment and is air transportable at high altitudes.
