4.1.2.3 Removal of the Antenna Shipping Retainers
a. Open the hatch (5/32 hex key [12572007] on the 73" radome). (Press in on latches on the 79"
radome.)
b. Cut the tie-wraps that go through the isolators that keep the antenna from moving.
c. Remove the red tie down straps holding the positioner.
d. Verify that the antenna moves freely in azimuth, elevation, and cross level.
4.1.2.4 Attaching Cables
a. Loosen the cable gland next to the access hatch and remove the plastic cap. See Figure 4-1, page 79.
b. Remove the two rubber rings from the gland.
c. Loosen the two cable clamps on the back of the strain relief of the control cable and remove the
clamps.
d. Put the plastic caps of the gland over the cable’s connectors (with the housing’s threads facing the
end of the cable).
e. Slide the MS connector into the gland of the radome.
f. Slide the "N" connector into the gland of the radome.
g. Reattach the two cable clamps to the cable strain relief.
h. Attach the MS connector of the control cable to the MS connector on the bracket mounted on the
radome (Figure 2-4, page 15).
i. Attach the "N" connector of the control cable to the same bracket.
j. Pull the control cable up into the radome so that there is no strain on the connectors.
k. Slip the two rubber rings over the cable. Push the rubber rings into the gland (the smaller ring
mounts next to the cable; the larger ring wraps around the smaller ring).
l. Tighten the plastic cap to tighten the rubber rings about the cable. See Figure below.
m. Seal the gland with RTV silicone or similar material.
4.1.2.5 Antenna/Pedestal Mechanical Checklist
a. Verify that the antenna moves freely in azimuth, elevation, and cross level.
b. Verify that the elevation assembly is balanced front-to-back by observing whether it remains at any
given initial position without moving up or down by itself.
c. Verify that all wiring/cabling is properly dressed and clamped permanently into place. Verify that
the tracking pedestal does not run into any objects or wiring in the radome base.
