Radios and Radio Frequencies
Diplomatic Missions and International Organisations must request authority from Ofcom to use radios/radio frequencies during VIP visits to the United Kingdom.
Requests should be submitted in writing to the Protocol Protective Security and Arrival & Departures Team (PSAD) (VIParrivals.departures@fcdo.gov.uk), ahead of the visit, with the following information: bandwidth, frequency range (also known as the spectrum), any preferred frequencies, area of usage and power output.
Details of any other communications equipment to be used during the visit must also be provided with as much detail as possible so that authorisation for use can be obtained. Please note, the import and use of electronic countermeasures (ECM) or similar devices to jam radio frequencies is not permitted.
