Default 100 Ohm Twin Lead

Nobody said anything about tying the braid and center conductor
together. If the side by side run of 50 ohm coax is used as a
parallel feedline, the braids are tied together and the Z0
is 100 ohms when the center conductors are connected across
the load.

you are great cecil, you cut out the original post to make it look like i
had nothing to do with the original statement... if you will remember he was
asking if he would get 25 ohms if he connected the braids together without
the center conductors... i simply say that if you connect both the braid and
center conductors you get a 25 ohm line... the implication being that if you
don't connect the center conductors you don't get a 25 ohm line.

thanks for keeping the fight thread going so well, now that you are riled up
i guess you can branch out into some other threads and bog them down for the
rest of the week.

Here's the original posting:
************************************************** ************************
I have an antenna that needs 100 ohm twin lead to match the impedance
of the feed point. The 450 ohm lead has messed up the match and
screwed up the resonance, does anone know of such an animal?
K4WYS
************************************************** ************************

It bears no resemblence to your assertion above.
