It is well known 3-phase power line transmission is more efficient than the
regular single phase. The PA is OK. Can anyone provide a circuit diagram
for a 3 -phase SWR/Forward & Reflected Power meter. Thanks in advance.

You will need the 3-phase aerial first, Reg.

That's easy to model with EZNEC and three sources.
What I want to know is whether it is Y fed (four wires)
or delta fed (three wires)?

Star feed would mean that there would be an earth up there. Might be
useful for grounding?

If it is Y fed, and the voltages are balanced, you don't need a fourth wire.
Everything will be nice like a balanced delta feed. As you know, when things
get unbalanced, both systems have their disadvantages.
