I agree with you, our neighborhood HAS to have the 2nd wire for return to be
safe. There is a wire that I thought was the return, but our phone and cable
lines are hung from that wire, and although my eyes aren't what they used to
be, it looks like that cable is sectioned from pole to pole, not a continous
wire. I'd sure like to talk to one of the Power guys and get the answer to
this. All our cables are buried after they come off the service poles, which
is cool, but if that cable supporting the phone/RF cable lines is the return
line for power, I'd think that would cause a possible danger to service
personnel. If there is any voltage difference between the return line and
physical ground, there would be current flow between the two, thus your
ladder touching the support cable/return line could possibly be the source
of fireworks.
Although that would explain the hum in my phone.
