The discussion has included hollow tubes. What if the tubes are solid? Does extra internal mass/density do anything?
As I understand it, radio frequency energy travels on the outside, or skin of a conductor rather than through the conductor like DC current, so in my opinion the solid would just be heavier – there would be no noticeable difference in antenna performance.
If the width became significant, say a foot or more, would the FCC measure vertical plus horizontal for their final “length”?
Not even the FCC seems to be able or willing to really address those kinds of questions. It seems to be very much up to the individual field agents.
One trend that can be observed in the Enforcement Bureau’s Field Notices web site is that those kinds of experiments do not, so far, appear to generate any field notices.
Despite much chatter about the legality of things like capacitive hats, loading coils and even kit-built transmitters, it appears that only excessive ground lead lengths (which result in some kind of intended or unintended dipole) and/or ridiculous power levels really get the enforcement attention.
