Default Antenna combiner/joiner question

No antenna perfectly eliminates the back lobe. Some just do better than
others (like a solid parabolic dish). The bow tie antenns will receive
some signal in the reverse direction. If that back lobe reception on one
combines out of phase with the front lobe of the other, it will reduce
the total sign somewhat.
