That’s Hertz, Q breath.

What about fox hunting? I’ve seen some antenna farms (arrays) that looked like that was their purpose.
I used to have a mini farm on my car’s roof, but no 6 footers - CB, police band, radio
a rotatable antenna is most often used for that.
you could have a nonrotatable directional array but difficult and limited on a car.
a ham might have use in 20 frequency bands. a car could have a lot of antennas. with the short wavelengths a person might have a directional array of antennas as well.
