I don't think it works like that.
You might not think it does, but the reality of it is, cowboyro is quite correct.
The primary factor required in order to generate a decent amount of a radiated signal, canceling excluded, is one needs a radiator tuned to the to the frequency to be radiated, which for a 60Hz quarter wave antenna is roughly 4 million feet, and unless you are dealing with a rather large structure I am willing to bet that is probably not going to be found in a straight run.
