This may be (ok, it IS) bordering on off topic, but what requirements were
there for coax? For example, could I use any RG8 such as RG8-U, RG8-X, etc?
What if I tried to use RG6 or RG59 (~72 ohm impedence as opposed to 50 ohm
in RG8 and RG58) This makes little difference in the RF world. Is it
different in the network world?
What about shielding? Obviously the more the better, but were there minimum
requirements?
Has anyone ever tried running over Belden 9914 hardline or some of the other
high end coax available?

A couple of thoughts:
o Yes, good old RG8 Etherhose is alive and well. I was gratified to
see that we still have some in the ceilings giving good service,
despite the advent of UTP. Ethernet runs 10mb/s over RG8
(thickwire), RG58 (thinwire), or UTP and thick is rated for the
greatest distance between repeaters.
o I don't think that RG8 is rated for outdoor or buried
applications, though. You'll need to install it in ducts if you
plan to put it underground.
o 1500m is still not a lot of distance. Consider optical carriers,
for which you *can* find outdoor cable since telcos use so much of
it.
o I don't know what things cost in SA, but in US the cost of putting
cables in the ground or hanging them on the poles is going to
make the cost of buying the cables look insignificant. Plus you
have to pay to acquire right-of-way through private property, or
to use some other utility's right-of-way. Outside plant is
incredibly expensive.
o Check your local laws to see what regulations might affect your
organization. Do you have to register with the government as a
common carrier? then how are you obliged to behave? You need a
lawyer.
