Myself I'd probably stick a small 3 el yagi on that
lamp mast if you had room..
Good bit more punch for SSB, and being things are
reciprocal, it will improve reception. If you squeeze
an extra 6 db from the antenna system, that's like
taking 50 watts and turning it to 200.
Best deal on an "amp" you will find..
I'm not sure the gain using a halo, but I suspect
it's probably pretty close to a dipole. Maybe a tad
more, but it's not going to be a drastic difference.
A loop has some gain broadside vs a dipole, but I'm
not sure what you get running one on it's side.
I forgot that the OP wanted horizontal polarization. Well, if it were
me, I'd make the loop vertical and feed the bottom center. That will
produce a horizontally polarized signal much better than the horizontal
loop and with about the same directivity.

A 'Halo' is the usual answer, or if more space is available crossed dipoles.
