Wow. ๐ I was a radio DJ for a couple years but did *not* know this. Is it same for AM and FM?
@ColesStreetPothole @HikerGeek No; FM broadcast antennas are comparatively quite small. The tower structures for them are just to get them up high and should not themselves be energized with RF. But the RF fields near the antennas can reach dangerous levels. (You can't go to the roof of the World Trade Center, which hosts a bunch of FM and TV stations, without special precautions, for example).
@[email protected] @[email protected] Ah, okay. I was an FM jockey, but we never got to see the tower, it was miles away.
@HikerGeek @mattblaze Jeff Geerling can be pretty funny.
How are such towers climbed safely if a technician is needed?
@JamieGC @HikerGeek You turn the transmitter off first.
@[email protected] @[email protected] that should have been obvious I suppose. ๐
