[TowerTalk] CAT 5 for SteppIR Remote Driver?

[Steve Jones]

Has anyone here used SteppIR's Remote Driver board with CAT 5 cable for a 
long run to the tower?  I want to pull some CAT 5 in my conduit for future 
stacked SteppIR antennas.

Do I need a separate CAT 5 cable for each antenna's Remote Driver, or can a 
single CAT 5's four pairs handle two SteppIR antennas?

 I see lots of CAT 5e on the web pretty cheap.  Anything special about the 
type of CAT 5 I should use?

SteppIR's website has no details.
