I just finished building the four coax cable combination and it did not work for me. I used four runs of Belden 1505a using only the center conductors for the pins and the shields were connected to the barrel of the source only. I got some kind of fine interference pattern on my picture - kinda like diagonal crosshatching. Not sure if its rf or the fact that the combination is not true 75 ohm. I rebuilt it with only two runs of 1505a and everything was fine again. Compared with 1406b, I could tell no discernable difference, even though 1505a is a larger RG59. My run was 18 feet.

Hmmm, that's a strange result. The only thing I can think of offhand is perhaps try connecting the shield at both ends. Sorry it didn't work for you. I'm using double runs of Belden coax pair (can't recall the parts number offhand; they are paralleled 75ohm minicoax), six feet in length, and this configuration works extremely well for me.--daryl
