 Jim, 

That's something I don't really understand. Why do you get the same loss in 
coax if you run them parallel? If you run "normal" wires in parallel you reduce 
the losses due to the lower current in each from the conductor RI^2 loss and 
the V^2 loss in the dielectric, even if that's not a big deal at, say, 60 Hz. 
Why not the same for coax? Yes, if I parallel two coax I need to use some 
matching to get the 50 ohm (or whatever I have).

And as you probably know, the loss in dB in parallel runs of coax, 
whether connected in series or parallel, is the same as in a single run 
of the same coax.
