Real interesting comments from everyone in response to my questions--thanks.
Yes I assumed some sort of balun would be used--I made no mention of it
because it is a standard part of yagi design usually so I figured its
inclusion was generally understood. Someone wrote that the f/p Z doesn't
matter--the whole point is to have 1:1 vswr at the tx--I laughed when I read
that--it sounded like a justification for a big resistor at the tx (just
kidding). Anyway, if low vswr were the only consideration I'd suggest a
regular yagi paired with a remote controlled feedline transmatch up on the
tower, however the ability to perform a 180 degree flip and bi-directional
operation are unique advantages.
