Well, no.

Put a BNC T connector on antenna one and feed one side of the T with your
52 Ohm coax feed.
Connect the other side of the T to the RG62 quarter wave section
(((468/145.8)/2*12)*.85)=16.37" Connect the remaining end to the other
antenna.
Just like a Turnstile.

I have a feeling a better match can be had by using nylon hardware on the
driven element, eliminating the gamma match, and driving the dipoles
directly.
