[Repeater-Builder] Transmitter combiners

[Gareth Bennett]

Hi there Group :-)     Is there somebody in the group who has knowledge on "Star" transmitter combining? I am trying to remember the formula for the "Tuning Stub" that also is fitted to the star, or "Porcupine" as we call them over here. All the stubs here are less than 1/4 wavelength (Including VF of cable) and as normal are shorted at the end :-) ..     Everything else is as one would expect with the food chain going like this... Transmitter-Isolator-Cavity-"Porcupine" - Antenna.     I want to tune this as best as I can, but don't want to spend large amounts of time hacking off coax :-)     Any formula would be appreciated. I have tried to reverse engineer what we have in service to gain some formula, but nothing makes sense.   Can anybody remember?   Thanks in advance :-) _________________________________________________________________   Gareth Bennett   This e-mail is confidential, if you received this message in error, or you are not the intended recipient, please return it to the sender and destroy any copies.
