[TowerTalk] Open Wire Entry To Shack?

[Pat Barthelow]

Have been reading the mail, and have a question regarding how much 
distance should be held beteween open wire line and adjacent conductors, 
be they, other coax runs, antennas rotor cables, etc.  We at N6IJ are 
running 450 ohm "window" ladder line thru a plexiglass panel, but want to 
also run other contductors.  We also have a TCI commercial/Military 
Balun, 50 to 600 ohm, with the parallel terminals about 10" apart, 
requiring heavy diameter parallel conductors to maintain the 600 ohm 
impedance.  How far away from a 10 inch spaced parallel conductor, should 
we keep other conductors?

Tnx, 73, de Pat, AA6EG/N6IJ, The Contest Station from the government...
