Packing Mast and Accessories Kit. After the antenna system has been lowered and

disassembled it must be packed. Packing will protect the antenna system from damage

during shipment to a new site and ensure that all antenna components are included and

available for the next installation. The following steps will provide you with the proper

method of packing the mast and accessories kit. Refer to the Fold-Outs specified with

each step so you may identify the parts as they are discussed.

STEP 1:

Open Fold-Out 3 and refer to View B while reading this step. Set the female

end of a mast section over the cap on the underside of the top of the launcher.

Then drop its male end over the corresponding cap on the base plate. Repeat

this procedure with the other five mast sections until there is a total of seven

mast sections in the launcher.

STEP 2:

Refer to View B of Fold-Out 3 and locate each part referred to in this step.

Release the loading catch on the base plate of the launcher, which will

telescope an additional three-fourths inch, and lock the stored mast sections in

position. Lower the mast section remaining in the erection mechanism by

manually operating the brake rings until the mast section seats in the azimuth

plate. It may be necessary to rotate the azimuth plate to allow proper seating

of the mast section.

STEP 3:

Swing the retaining clip on the top of the mast assembly over the top of the

mast section stored in the erection mechanism.

STEP 4:

Refer to View A of Fold-Out 3 while reading this step.

Snap the binding wires to their lugs at the top of the mast assembly and

tighten each of the canvas straps around a pair of binding wires.

STEP 5:

The accessory kit should contain the items shown in Fold-Out 8. Secure the

guy attachment ring by snapping the snap hook of one guy wire thru it, wind

all guy wires on the snubber brackets, and place these and the remaining items

in the accessory bag.

STEP 6:

The mast extension kit is shown in Fold-Out 9. When a 50 ft antenna system

is disassembled be sure these items are replaced in the mast extension case.
