Here is the rule on that:
Users of nonlicensed, low-power
devices operating under part 15 of this
chapter may use whatever identification
is currently desired, so long as
propriety is observed and no confusion
results with a station for which the
FCC issues a license.
47 CFR 73.3550(l):

Note that r-f power can be conducted from one place to another via a coaxial cable with its shield grounded, and still radiate essentially none of that power directly via that coax. This is the common configuration for AM, FM and TV broadcast antenna systems, where the tx is in a building near the tower(s), yet the r-f power entering the coax also appears at its termination (less I^2R loss in the coax), where it is radiated by the antenna.
That is obvious, the point I was trying to make is that from an extreme interpretation of Part 15 (b) that no ground could exist except for dirt. I also just meant that there would be some radiation from the coax shield even if it was a good power transfer system.
I are not in the business of interpreting FCC law, I just recommend that people follow the law and cooperate with the FCC. Contact the FCC for law interpretation. I may try to let people know what other customers have done successfully, and what other agents have passed, but in no way am I purporting breaking any law. six foot pole, ten foot, twenty foot, fifty foot, who knows? Only the FCC agent that comes calling and how HE chooses to interpret the law, nobody else.
I think scwis is right, a lot of enforcement is driven by broadcasters. If a Part 15’er isn’t getting rating points in his town, then I would think local broadcasters would not consider him competition.
The good thing like I have said before is that if you do get a visit from the FCC, I have found that without fail they are good guys, they will work with you to find a solution and will cut you a break when they can. I have never heard of one of our units being shut down, if an agent sees something he doesn’t like typically he will give you a paper detailing out how to correct the issue, and typically allow you to operate until he returns to approve your changes.
