I'm afraid the theory isn't there. Twinned coax runs don't significantly 
change the losses involved. At least, not in theory.

Can you do A / B comparisons with the coax fed, dual-coax fed and open 
wire fed antennas in identical installations / locations similtaneously? 
Is your signal source a single, known strength, or does it vary with 
changes in the ionosphere?

Seems there's still a lot of untamed variables here.
