NOTE
Once the antenna has been installed (connected to a transmitter or receiver and supplied with
115 VAC for the tower light assembly,) it becomes a completely passive equipment item from the
standpoint of the operator. Once operational, operator interface with the equipment will be
restricted to the performance of PMCS tasks addressed in Section II of this chapter.
Section I. DESCRIPTION OF CONTROLS AND INDICATORS AND USE OF INSTALLATION WINCH ASSEMBLIES,
ROPE TENSIONERS, AND CABLE CLAMPS
2-1. OPERATOR'S CONTROLS AND INDICATORS
There are no controls, adjustments, or indicators in Antenna Group OE-317/TSC-99.
2-2. INSTALLATION WINCH ASSEMBLIES
Raising the antenna requires the use of three winch assemblies. These three winch assemblies are furnished with
the antenna and are described and to be used as follows:
a. TOWER WINCH ASSEMBLY
The single tower winch (Winch, Spur Gear 2000 lb.) is attached to a winch stand which is secured to the ground by
the eye of a 66-inch anchor (ANCHOR 6A). Operator interface with the winch involves the use of a winch handle for
feedout and takeup of the winch cable, a ratchet engage/disengage lever, a hand brake lever which is activated only
when pulled and held in position, and a wire/cable gripper on the end of the winch cable for attachment to the
stainless steel lifting cable of the antenna.
TO USE
Take a kneeling position on the crank handle side.
Move the ratchet lever to disengage the ratchet.
With another crewmember applying tension to the winch cable, turn winch handle counter-clockwise until enough
cable is extended to make wire/cable gripper connection to the lifting cable attached to the antenna.
Move the ratchet lever to engage the ratchet and turn winch handle clockwise to take up slack in the winch and
antenna lifting cables.
