I ty-wrapped about 30 feet of cheap Tandy coax solidly against 
another piece of the same coax, and tried to measure the crosstalk.

I had more leakage from the cases of the equipment than through 
the shields, and cross talk was far below what an antenna several 
hundred feet away would produce back in the shack.
