Jim,
I would guess about 120 kV for the voltage on those lines. You will be in
the near field of the lines and you will get hum but I don't know how much.
Also, do not run an antenna parallel to those lines! The induction field
will induce a possible lethal voltage on the antenna from transformer
action. I have experienced that senario.
All in all, I would not go there.
