ref : 47CFR15.217(b) The total length of the transmission line, antenna, and ground lead (if used) shall not exceed 15 meters.

The above excerpt is from the Part 15 section regarding non-licensed operation in the frequency range of 160-190 KHz.

My question: If the antenna includes a "top hat", be it centered, totally off to one side (eg an Inverted-L), or non-symmetrical (eg 30% to one side of the feed / 70% off to the other side of the feed) how is the top hat figured into the "15 meter" total length?

For years I've heard "Philadelphia Lawyer Curbstone" opinions. But "officially" has the FCC ever put the top hat clarification in writing and published their interpretation?
