Le PMR446 omologate devono essere conformi alla normativa 1999/5/CE e secondo le indicazioni CEPT/ERC 2015/5/ECC.
Tale norma riguarda:
The harmonised frequency range 446.0-446.2 MHz, technical characteristics, exemption from individual licensing and free carriage and use of analogue and digital PMR 446 applications
Nel testo si riporta:
The equipment is hand portable (no base station or repeater use) and uses integral antennas only in order to maximise sharing and minimise interference. PMR 446 equipment operates in short range peer-to-peer mode and cannot be used neither as a part of infrastructure network nor as a repeater.
Nello stesso codice delle trasmissioni le PMR446 sono ritenute tali se conforme alla normativa EN 300 296, tale normativa riguarda:
Radio Equipment and Systems (RES);
Land mobile service
Technical characteristics and test conditions for radio equipment using integral antennas intended primarily for analogue speech
Nel documento si trova:
integral antenna: An antenna designed to be connected to the equipment without the use of a 50 Ω external connector and considered to be part of the equipment. An integral antenna may be fitted internally or externally to the equipment.
Tipicamente le versioni export nascono con antenna removibile e potenza aumentata.
Le modifiche tipiche sono, appunto, l'aumento della potenza ed il montaggio di un connettore SMA o BNC per l'antenna.
