<---You don't use "62.5 ohm" coax. You build a transformer (1/4 wavelength or odd multiple of a 1/4 wavelength) out of "conventional" coax. Electical 1/4 wavelength of course, not physical :-) On the other hand, some would argue the mismatch between 50 ohms and 75 ohms is hardly worth the effort and would simply return their duplexer to match the different common port impedance.
