"....Besides using a 4:1 balun and then running coax, you can
do away with the balun and use balanced coax.

Bill, attachments don't make it thru the list reflector.  Are the
photos up somewhere else where i could have a look?

Also- is this correct: the 2 coaxes run this way, as a balanced
coax, 4x the impedance of the single coax?

And if so- let's say we do this, raising the impedance, let's say
we then want to retain the balanced coax idea ( more for noise
suppression and ground independence ) but want to have the
line impedance the same as for a single coax span. How many
"balanced coax" pairs do we need in parallel? 2 or 4? Just
curious.
Tnx, Hue Miller
