Repeater in cell phone tower
Sounds like good setups all around right now we are also going
to do a similar thing with the local telco , we're going to do some websites
and hosting in our US Colocation for them and in turn we get access to all
there telco towers (10 or so of them) best thing is CELL TOWERS ARE EVERYWHERE
TO GET GOOD COVERAGE so as long as you follow the cell towers you know youll
be able to do wide coverage area's, also something nice we worked out with the
telco is the fact they have a fiber ring going to all the towers and there
DSLAMS for the telco's dsl service so we are going to work out bringing the
entire infrastructure back to our NOC on Fiber because we already have a few
fibers from them that are just sitting there so booya instant infrastructure
expansion but like he said Keep the radio's on the antennas minimum cable 0'
if possible (barrels are nice) and also if your looking for good thick
saturated coverage use high quality sectors, HyperLink and Radiowave are both
good companies hyperlinks on the expensive side but they have really high
quality hardware we are redoing our entire network with there antennas and
amps partially the reason we don't have money for the telco tower expansion at
the moment :( But good luck with yours and it sounds like a good idea and your
thoughts on it using on the lower base as long as you have a good clear LOS
with no obstructions ANYWHERE close to block ANY of the beam to end up
reflecting back to you the signal then your set. Stay above tree's and rocks
and stuff that might be on the hill.

I would think this shouldn't be a problem. I'm hardly an
expert at this,
so this advice may be worth what
you're paying for it. Just make sure your
radios are
as close to the antennas as possible (so you won't need amps).
Sounds to me like what you're doing should be just
fine.
My repeater consists of 2 13dB panel antennas and 2 airPoints
in a NEMA
box. It's only supporting 2 people now, and
will not need to support more
than 4 due to the
geography in this area.
My next repeater will need to support several dozen customers
(or more!).
I'll have one aPPO feeding a switch and
the switch feeding 3 or 4 aPPOs.
.at least... that's
the plan for now.
