The Reason I question this is because I did Not Notice any Insulators
at the base of the tower seems that its Metal sitting on the concrete
Base. Nore did I see any straps from that bottom section Down to the Ground.
I would Think that If the bottom section of the Tower was also HOT
there would be Insulators at the Bottom also to prevent any arcing
across wet steel reinforced Concrete
I would have thought the Gain came from the 2 Towers In Phase as a
Dual vertical dipole array.
so your saying in fact that its 4 sections feeding 180 over 180 in phase
