Hi Norm, N3YKF

The two pieces of coax that connect the antennas to the power
divider/combiner to fed the antennas in phase can be any lenght
provided that both lenghts are equal and of the same type of
coax cable preferably cutted from the same roll of coax cable.

 HI all!
 Quick technical question. If I have a two port power divider/combiner and
 want to phase two alike antennas,  do the two pieces of coax that connect
 the antennas to the power divider have to be 1 wavelength? Can they just
be
 equal?
 The literature says that the divider must be fed in phase.

If you are phasing the two antennas to get 3db of gain with the same 
polarization, then the two cables can be any length as long as they are exactly 
the same electrical length.  It's a good practice to make two cables from the 
same batch of coax if possible.
