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,
and erection. Figure 2-5 illustrates the use of Adapter MX-9313/GR for use
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.
