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.
