315MHz like car systems? 497MHz? That does seem odd....what power level does

I have a horizontal directional drill. The drill bit transmitter (sonde)
talk to a receiver. They are pretty low frequencies, like 8 KHz or something
like that. Then the locator sends data to a remote indicator on the machine.
One of the antennas (the one on the remote indicator) was messed up and one of
my guys just put a random length of wire on it. Range is not good. I told him
I would figure this out and make a better antenna.
That is the easy part, I just swept the other good antenna and noted it
resonates at 479 MHz. Will make a sleeved dipole for it.
But now I am wonder if I ought to be licensing this thing?
I expected it to be in the 300 Mhz unlicensed band (316 or whatever it is).
Never thought it might be illegal until this morning.
FCC band plan shows the following for that frequency:
Public Mobile (22)
Broadcast Radio (TV)(73)
LPTV, TV Translator/Booster (74G)
Low Power Auxiliary (74H)
Private Land Mobile (90)
That is all licensed stuff.
