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. 73 de i8CVS Domenico -

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. - Howie
