Richard, are you saying to go buy two identical antennas and mount them
the same sans coax and then also put another reflector behind the 2nd
one, ending up with a 3 element Yagi?

"If you want an expected outcome, you do what you have to do and get on

with it. In your case, if you are seeking elegance you would then buy
two more units, clamp them base-to-base, put them about a 20th wave
behind the first two, and tune the reflector (make it bigger) by that
same roughly 5%.
