No he didn't. He asked how to feed them with a single co-ax. He didn't mention phasing. He said they were mounted one horizontal and one vertical.
The problem with phasing lines is that he said they are dual band antennas. If they are single feed, your phasing lines will not work on both bands.

Mr. Gunn,
He specifically asked how to phase them. Using a relay to switch between them is an obvious solution that he apparently didn't want to use.
If you want to combine two 50 ohm loads into one, my suggestion is correct. Not gibberish. It is a variation of the Wilkinson combiner/splitter. Read up on it.

Unfortunately, Brian, you're getting mostly gibberish that you didn't ask for.

Hello Everyone,
I have two Dual-Band 2 Meter/440 Yagi's that I would like to use on a Rotator, with one in the vertical polarity and one in horizontal.
Is there a phasing circuit or system that someone can recomend to allow both of these antennas to coexist on one coax input to my radio?
Thanks,
