i gave this a try. i could not pound an 8ft (live in apt's) rod in the ground but was able to get about a 2ft rod in ground.
signal did not travel more than 25ft from building and did not jump to other buildings.
very strong, sounding great in and around building but not much beyond building.
used a TCU-30 and one of those greek rack mount AM's 20W (80W PEP)
Never have really seemed to have any good luck with Carrier Current, always seem to wind up in a bad area for it.
