I happen to be (in the past) a radio "Ham" and know about harmonics.
At least for HF frequencies such as in the 10, 20 and 40 meter bands.
Did bothered neighbors around my antenna into their regular receivers.
But I could not say what would be the case if/when on VHF/UHF.
I never practiced with these frequencies.
