 To tell the truth, I have a very limited idea of what will end up on the
tower.
 I know that there will be a 10 element (or so) 2 meter, A 20 meter beam (of
some kind)
 I am not sure if I will place a 10 meter beam in that stack or place it on
top of my 40' rhon 25 that I will dismantle here and move to the new QTH.
 Yes UPS is here area code 29485

 You see I have a lot to think about, I just want to have a plan here. It is
a lot easier knowing what you need ahead of time.
 For instance if I was going to go for the long mast option,I could drop the
mast sections inside the first tower section during the tower build and not
need to drop them in from the very top of the tower.

 The tower will be a rhon 45 between 60 and 80' tall.

 I could do with a rhon 25 but with the difference in price between the 2
the 45 (and after talking to you all here) the 45 makes more sense, plus I
could go higher with the 45 if I wanted to later on.

 Any options or ideas are welcome.

 PS. Thanks for being an elmer, Amateur radio is one of the few places left
that people will help each other without a price tag attached.



Merlin - Maybe I can help you, a lot actually - How large an antenna are you
putting up on this tower and what height? These may be inconsequential
questions so I should say," How large does your rotor need to be?" I have
tried to Elmer in a few newer hams before and I might be able to come up
with you a good used rotor. If it was large enough for your install. I have
a few here and would have to go check them out and see what I have on hand.
I feel that you are talking about coming up with more stuff here than a good
used rotor ( rotator ) would cost - dependant on size of course. I should
also ask- are you in an area that is served by UPS?

I like the chain thru the side of the shack idea.

 What if, I ran the chain thru some pipe between the gear on the mast and
the gear on the steering wheel inside the shack? It could be pvc as long as
I support it well at the tower and the holes drilled thru the shack would
support that end. Plus that would stop a lot of the problems with the chain
being exposed to the weather...An iced up or rusted chain  would really
suck!
 Putting the chain in a pipe or tube should do away with any slack that
would tend to derail the chain and is very easy and cheap to do.

 Also, it would be easy to make the hardware to attach a sproket to the
mast.
 I was thinking instead of bicycle chains and sprokets useing some 530
motorcycle chain and sprokets. Any mortorcycle repair shop should have some
used ones cheap.

Any more ideas?
Joe
