[TenTec] Dipole Over Pool Enclosure

I wouldn't be too concerned about the dipole over the pool enclosure.  It 
would be quasi like a dipole over the earth at a height of 5 ft.

I would be concerned about the Titan amp, specifically running that much 
power, as some of the aluminum structure might appear with some interesting 
resonant nodes.  Also, the typical poor and oxidized mechanical connections 
of the pool enclosures I've seen might act like a diode junction and 
generate RF due to the rectification between dissimilar metals.  Generally 
this is not RF you'd be proud to claim as the owner.

Also, I'd say that any occupants under the antenna, in and around the pool 
are likely to be exposed to RF fields in excess of those prescribed by the 

You're a ham, try it.  If it smokes, then you know it was a bad idea.  If it 
works, then enjoy the DX.    If the neighbors complain about RFI then look 
for more real estate.  Basically I say "more power = more problems".
