Transmitter combiners
Gareth,
For two transmitters the length of the circulator
to porcupine jumper would be 5/8 wavelength in coax.

When these two are parrelled the common
impedanceis 25+j25 ohm.
Looking at the Smith chart it looks like a
paralleled s/c stub of -j25 would acheive a match to 50 ohm.
