I agree, why would they contradict factory advice of one of their suppliers?
Presumably the tower manufacturer feels responsible for the overall
engineering of the system, mindful of the environment it will be used in. It
may be optimistic to assume that USTower adopts such a benevolent attitude.
I don't whether they do or not. The people I have talked to there seem
reasonable enough and are willing to answer questions. They seem to have a
lot of experience with their towers.
I am in process of putting up a ma-770 tower. I also asked USTower about
lubricating the cables and they said don't. They had several reasons for
this advice. The ones I remember are: (1) most lubricants tended to collect
debris, twigs, dirt, etc which interfere with the cable path, (2) they had
heard anecdotal reports from users that penetrating lubricants, that would
not collect debris, seemed to hasten rusting, but they did not have evidence
on this themselves either way, and (3) in their experience they had never
had any trouble not lubricating the cables over several years of use. I
don't remember them mentioning what the cable manufacturer recommended.
I'm just the messenger.
