GENERAL INFORMATION

INTRODUCTION

1.0

This instruction manual contains technical data, installation procedures,

theory of operation, maintenance instructions, and an illustrated parts

list covering the AS-2259/GR Manpack Antenna and the Adapter, MX-9313/GR.

The antenna was designed to be used with short range tactical hf radio sets

that use a 15-foot whip antenna, such as the AN/PRC-47. The Adapter, MX-9313/GR

is used to interface the antenna with heavier radio sets such as the AN/TRC-75,

AN/MRC-83, AN/MRC-87, and AN/TSC-15.

The instruction manual is divided into five sections. These sections provide

general information, installation procedures, theory of operation, maintenance

instructions! and maintenance parts lists.

1.1 EQUIPMENT DESCRIPTION

The AS-2259/GR Manpack HF Antenna (Figure 1-1) is essentially a dipole antenna

fed with a low-loss, foam-dielectric, coaxial mast that also serves as a support

structure. The dipole system uses a set of crossed sloping dipoles positioned

at right angles to each other. Physically the antenna consists of eight light-

weight coaxial mast sections and four radiating elements that also serve as guys.

The antenna is transported in a canvas pack similar to a tool roll. The total

packed weight of the antenna is 14.7 pounds. Erection is accomplished by two

men in 5 minutes without the use of any tools.
