Not sure it can work for Part 15 AM, but given the 10-foot limit, maybe!

Yagis work with high freq
Yagis work with high freq horizontally propagated signals. The thing on her hip is probably a 2-meter transceiver. It will not work with AM bcb signals, so the 10 ft. rule is non-sequitur.
Now, how about a 3′ dia. LIFEFLOWER antenna (the normal designs are small … 11mm for cellphones):
You’ll have to look it up … the URL I sent keeps triggering a spam filter.
Multiband, no grounding (as we know it). I plan to build one someday … just to see what happens. The modeling programs would likely not do that great a job of predicting range patterns with fractal antennas of the size I’m cosidering.
The reason webphones can do what they do is because they can operate on multiple freq’s and on different bands in the microwave domain. That means the antennas must have multi-band / wide-band capabilities, which is precisely what fractal antennas do.
To be honest, I really haven’t a clue how one 273x larger would behave. But it will make a nice garden decoration in any case 😉
