is similar to what I am building but for 137MHz (the one in the pic is for a
higher frequency).

The two dipole elements are horizontal and 120 degrees apart.

Do the reflector elements need to be connected together??

Do they need grounding ?? or connecting to the feed in some way ??

Dave,

If you are going to build something the QFH antenna would be a better choice
for APT/LRPT 137 MHz reception, for example:

but search for more recent links.
