Installing the Link CX 69
Inspection and Maintenance
45 Before leaving the installation, check that all hardware on the mount, shroud, radome, and
feed is tight and that nuts are locked in place.
46 Inspect the antenna at least once a year to check its condition and to insure safe operation
and maintenance. Qualified personnel, knowledgeable and experienced in antenna installa-
tions, are required for this inspection.
Supplemental Information
Table 4-8 is provided for installers unfamiliar with adequate nut tightening procedures for use on
stainless steel bolts, U-bolts, galvanized bolts or any bolts without the ASTM-A325 marking on the head.
Disregard these recommendations when specific tightening requirements are given.
Note: It is not recommended to reuse a palnut that has already been fully tightened or deformed
in any way. It should be replaced with a new palnut.
Weatherproofing the Type N Female Connector on Feeds
Remove the protective cover from the end of the feed and mate the connectors, screwing the male
connector firmly onto the feed.
Important: After connecting the coaxial cable, wrap the Type N connector with the gray butyl
rubber, squeezing it firmly around all joints to make a continuous seal. Finish the weatherproofing
by wrapping the butyl rubber with several layers of black PVC tape (not supplied).
Continue with Section 4-5 to complete the Link CX installation.
