When we co phased 2 11M. Antennas we used a Phasing Harness RG-59/U coax is
what the sellers had I recalled they were 1 / 4 wave length apart, I presume
thats the case with the Sinclairs using a 1 /4 wave to 1/2 wave config.
each cable that is to PL or N connector ( never did it w/ N BTW ) the cable
may be a different type also .
anyone want to input on this ??
