John, When you view the 2 antennas from the rear (let's say...) Both center
conductors of the feed coax should go in the same direction - either both
right or both left. If one antenna is "flipped" and they are identical there
will be a phase cancellation. With the looper, you need to rotate the driven
element loop in the boom 180 degrees. This is best done by unsoldering the
connections (center conductor and and shield and spinning the loop ( loosen
the nut first...) then resoldering.. You can do it with a nice hot iron in
about 10 seconds if you have done 356,000 of them like i have..
What you want is driven elements that are mirror images of each other.. This
is trickier with the K1FO Yagi and you're probably best off mounting them
both "rightside up". Running the coax around the boom won't hurt anything -
you most likely are doing it at the mast anyway..
