As for WHAT it is, it is a "doublet". A lot of Hams call a center-fed
antenna a "dipole", but the term "dipole" is reserved in the engineering
world for a half-wavelength long antenna no matter where or how it is fed.
If it's not a half wavelength long, it's not a dipole.

I, too, run a doublet fed with open wire line, although it is not as high
nor nowhere as well placed as yours!

The lobes are very broad on the lower bands. "Oceania" is NW of Georgia (the
last Georgian I knew would answer your question about what's Northwest of
Georgia with "nothing important".)  Anyway Australia is due west of you and
India is due North. So NW is everything in between. On bands above 40 meters
the pattern will break up into many lobes so you will have lots of signals
going every which way. If you'd really like to model that antenna, I suggest
picking up EZNEC by Row Lewellan, W7EL. It is a very powerful antenna
modeling program that runs in Windows. You can get a free trial version that
would handle your antenna for the effort of downloading it from
http://www.eznec.com/index.shtml  If you get into tinkering with more exotic
layouts, you will want to buy the full program. It's very reasonable.

I have no connection with W7EL other than being a very pleased customer.
