Hi, Dave --
Congratulations on getting your new tower and antenna system installed.
Quite a project, eh?
As far as a PE, I don't have any contacts in your neck of the woods. If
you just want calculations, any sharp engineering person can do it. A PE
stamp is only required for obtaining a building permit. Since your tower is
already up, all you really need is to have someone run some calcs. Ask
around your local radio clubs, repeaters or packet clusters and I'm sure
there's someone around that can help you. If that doesn't turn up anyone,
try posting your request on TowerTalk.
Another thing you can do is to read Roger Cox's article from Ham Radio
magazine, June, 1984, about doing the calculations yourself. It's got a
bunch of charts and information to help you. An SASE to TOWER TECH, Box 572,
Woodinville, WA, 98072, will get you a copy.
>Also, you mentioned a special lightweight cable lubricant for tower cable

How much? Like to >have enough for atleast a couple applications. >>
TriEx recommends a spray-on lubricant called Prelube. I'm trying to
find a product that I can sell but am still working on it. In the short
term, you won't have any problems with your new tower but I'll let you know
when I find a good product.
73 and tnx for your interest, Steve K7LXC
