If your goal is reception of the major networks, ABC, CBS, CW, Fox, NBC and PBS then you don't need a deep fringe antenna. A small UHF panel antenna such as a U4000, DB-4, CM4221 or HD4400 facing west would do nicely. To mount this style antenna does not require extreme iron working skills. A satellite J-pole is often used. An eave bracket or chimney strap is another very good option.
If your goal is reception of distant weak signals, then a larger antenna would be needed.
I would not consider a couple of feet of iron or steel to be a substitute for a solid connection to the existing ground system.
