What Happens If You Happen to Touch an Active 6kW AM Antenna

Vlogger Jeff Geerling wanted to clear up just what might happen if he touched a 6kW AM transmitter's antenna.
IMPORTANT: Do not attempt to replicate our experiment. It is meant to demonstrate the dangers of RF, and there are a number of radio engineers, landscaping professionals, and other personnel who have written RF safety rules with their blood (or, in most cases, a permanent and painful RF burn that goes through the inside of their body). Don't touch radio towers-AM or otherwise.
[...] You really should watch the video for the full effect, though. Pictures can't convey what happens.
I predicted the hot dog would either explode, or do pretty much nothing. My Dad imagined there would be some arcing.
Well, he was right-the hot dog wound up being a very effective loudspeaker, transmitting the audible sound with pretty high fidelity, at a volume around that of a yelling human, maybe 80-100 dBa. (Next time we attempt such an experiment, we may bring a dB meter and spectrum analyzer to judge the sound reproduction capabilities of different meats1).
The bottom line is that experts recommend not messing with live towers. The fence is there for a reason.
