Perhaps I'm missing something but using a "phasing harness" with coax cut 
for a electrical length (usually a 1/4 wave of 75 ohm coax on either side of 
a "T") only works for a narrow band of frequencies.  If you are using a wide 
band power divider, then you can use two identical lengths of coax cut from 
the same roll.  It that case, the electrical length isn't a factor.
