Topband: Zo of an individual CAT5 twisted pair

[James Rodenkirch <rodenkirch_llc@msn.com>]

In an earlier post to this reflector, Carlos, N4IS, mentions using one pair of 
twisted wires out of a CAT5 cable to feed the delta loop antenna used by T6LJ.
 
I am assembling the pieces/components needed to put an "FO0AAA style" delta 
loop receive antenna up and want to use the twisted pair cable as well.,
 
My question is: 
 
 Does it matter which twisted pair of wires I use?
 
Thanks, in advance, for any thoughts....72, Jim Rodenkirch K9JWV
