[TenTec] Dipole Over Pool Enclosure

I think I would hang it and just see how it works, while carefully 
documenting impedance and other data for various frequencies and bands. 
  I believe ANY nearby large object, especially  one of made of metal, 
can affect the radiation pattern, or  or affect impedance, but you won't 
really know HOW if you don't try it.  I am no expert on computer 
modeling programs, but I doubt that would give you much of an answer to 
how this structure would affect a dipole, whereas the programs do 
consider different ground conditions.  Maybe you could look into the 
computer modeling programs, and see what sort of 
worst-case-metal-object-below-the-antenna scenario you can construct, 
and see if that makes any substantial difference.

But I say hang it and see how it plays...   then try the vertical Kris 
mentions... and compare them... and then try something else... and... so 
forth until you either get too sick or too old.       ;-)

Just MY take...
