.. never have understood what folks who sell those setups
are thinking... besides $$... Big power & big antennas on
the 15th floor -- and when the pager won't trip in the
basement X-ray room, it's a mystery... "must need a bigger
antenna"... Sheeesh..
You're on the right track thinking Radiax or such -- for
80-odd feet, 1/2" or 3/4" should do fine.
A good "leaky coax" setup is part science, part magic, and a
healthy dose of common sense and PLANNING -- if there's no
need for significant coverage away from the building, drop a
line ~down~ from the current station, terminated with a
simple 1/4 GP at the bottom. (Load? Don't want no stinkin'
Load !)
Elevator shafts are perfect *IF* your zoning/fire-code will
allow (and most places WONT). Look to centrally located
pipe-chase & service riser stacks -- maintain some spacing
from 'big-iron', and (excuse the shouting)
_USE_THE_PROPER_HANGERS_ & recommended spacing so the cable
isn't damaged. Andrew docs are very good references.
Then, there's convincing your in-house electrician that it
DOESN"T need to be in conduit... ;-)
Good Luck.

what do you guys know about the installation of radiating
cable for a repeater in a building. I have a 5 story
building and sub basement. So it is like 6 stories.
Thinking of putting the repeater in the lower level and
installing the cable up to the roof. On the roof thinking
a DB-408. (or would a dummy load be used) This would be a
UHF repeater possible 2 watts or other low power use. The
goal is to cover the floors as there are a lot of cement and
metal. At this time they have a repeater on the roof but
the lower floors are dead and there is very little receive
in the sub basement. The current repeater is 40 watts. No
preamp.
