Another example is PMR, aka. walkie talkies. In many countries, you can use the PMR frequencies unlicensed only through radios with non-removable antennas limited to 0.5W of TX power. Doesn't stop people without licenses from buying and using handheld transceivers intended for HAMs and professionals (like the popular UV-5R with 5W of TX power and a removable antenna) on these frequencies.
