GENERAL

Erection and disassembly procedures for the AS-2259/GR antenna are given in

the following paragraphs. Erection can be accomplished by two men in 5 minutes.

See Figures 2-1 through 2-4 for pictorial sequence of transporting, unpacking,

with vehicular mounted radios.

2.1

SITE SELECTION

For maximum antenna operating efficiency, the AS-2259/GR should be located in

the center of a clear area. Installation of the antenna near any tall metal

object or under heavy foliage should be avoided. Under no circumstances should

structures come in contact with the antenna.

2.2

ASSEMBLY PROCEDURE

WARNING

Be sure transmitter power is off before proceeding with antenna assembly. Electrical

burns will result if contact is made with the antenna when the transmitter is keyed.

Electrical burns will result if contact is made with the antenna mast of metal portion of

antenna guys.

WARNING

Antenna must be installed a distance equal to at least twice the height of the antenna

from power lines.

WARNING

When antenna is up for an extended period of time insure the mast indirectly grounded

through ground stake.

a. Open antenna pack and remove base assembly. Install base on AN/PRC-47

antenna input connector. Connect ground wire from base to ground terminal

provided on the radio.

b. Remove top mast assembly, install in mast base, and uncoil elements

(see Figures 2-1A and 2-1D). Note that the antenna elements are stretched

along the direction in which they leave the top housing and are not shorted

to each other or to the mast.

c. Measure anchor positions, using the sleeve cable markers as guides, and

install anchors as shown in Figure 2-1B.
