Wireless Telegraphy Act
The Radiocommunications Agency is the regulatory authority for most civil radio in the United Kingdom. Regulation is necessary so that all those who wish to use radio can do so without their transmissions being subjected to interference. The regulations governing maritime radio are, on the whole, contained in the International Radio Regulations and the Wireless Telegraphy Act 1949, as amended. The Act makes it an offense to install or use radio transmission equipment without a valid licence.
Frequencies
The use of frequencies allocated to the maritime radionavigation and radiolocation services is agreed either on a UK basis or on a world-wide basis by the International Telecommunications Union (ITU) of which the UK is a member. These frequencies range from LF (30KHz) to SHF (30GHz).
Antenna siting
Antennas sited on masts which are 30m or more above ground level, or 300m or more above mean sea level will require additional site clearance before we can consider issuing a licence. Site clearance is liable to add considerably to the time taken to issue a licence. It is therefore recommended that antennas are kept below these heights.
Shared masts on which to site antennas are commonly used. However, this may cause intermodulation interference problems between different users of the mast. In the event of such a problem we will try to allocate an alternative frequency (if it is not an equipment fault) but will not accept responsibility for such interference nor for costs incurred in either changing frequencies or vacating a mast. Please bear this in mind when deciding on your antenna location.
Erection of an antenna may require planning permission. Contact your local council.
Please enclose a letter of consent from the present licensee agreeing to the takeover
5 Give your full name
For a partnership, give the full name of one partner (this partner must also sign the declaration), and supply a separate list of the full names of all other partners.
Surname Forenames
7 What is the trading name, if any, of the business which will operate this service?
For a large operation, give the name of the operating division.
postcode
15 Indicate the proposed maximum Effective Radiated Power (ERP) in dBW
Note: ERP (in a given direction) is the product of the power supplied to the antenna and its gain relative to a half-wavelength dipole in a given direction. The maximum ERP is the ERP in the direction of maximum radiation and is expressed in Watts. The power supplied to the antenna is expressed in the form of peak envelope power (PX or pX). The peak envelope power is defined as the average power supplied to the antenna transmission line by a transmitter during one radio frequency cycle at the crest of the modulation envelope taken under normal operation conditions. The Agency will ultimately decide on the permitted ERP.
16 Indicate the frequency(ies) on which you prefer to operate and/or the total number of frequencies required
Please note that it may not be possible to assign the frequency of your choice.
17 Please give the class of emission including the necessary bandwidth
(See "Guide to Emissions" RA97)
Please note that for VHF DGPS the bandwidth should not exceed 12.5 kHz and for MF/HF DGPS it should not exceed 500Hz.
20 Please give:
(a) the address of the base station (include the postcode)
25 Give the National Grid Reference (taken from the current 1:50,000 Ordnance Survey Map).
If the National Grid Reference is not known, give the latitude and longitude
The application will be delayed if this information is not given or proves to be inaccurate.
Grid letters
Eastings
Northings
26 Give the height of the top of the antenna above mean ground level
azimuth degrees East from North elevation degrees from horizontal
29 If the antenna beam rotates give:
(a) beam rotation or azimuth speed
I declare that all details given in this application form are correct.
The information on this form is being collected on the authority of the Secretary of State for Trade and Industry and is to be processed for the purpose of issuing a Navigational Aid or Radar Radio Licence. Authority for disclosure remains with the Radiocommunications Agency and any requests for disclosure of information must be made in writing to
The Data Protection Officer Radiocommunications Agency Wyndham House 189 Marsh Wall London E14 9SX.
This information may be made available to the International Telecommunications Union (ITU) and the Maritime & Coastguard Agency (MCA) and organisations responsible for port operations.
Signature of applicant
Partnerships must apply by one partner signing 'For self and partners'
A director or authorised person should sign for limited companies and other organisations.

Please send this form together with the appropriate fee to:
RA4/AFS Radiocommunications Agency Wyndham House 189 Marsh Wall E14 9SX

Aeronautical and Maritime Services Radiocommunications Agency Wyndham House 189 Marsh Wall London E14 9SX Tel: 020 7211 0215/0217 Fax: 020 7211 0228
E-mail: ams@ra.gsi.gov.uk
The fee is calculated on the basis of per station or per frequency.
The first station comes with one frequency then each additional station or frequency is charged separately.
RADIO NAVIGATION/ RADIO LOCATION – The fee is £40 per station per frequency.
Example
1 station with 1 frequency = £40 1 station with 2 frequencies = £80 2 stations with 1 frequency = £80
DGPS – The fee is £250 (VHF) / £1000 (MF/HF) per station per frequency
1 station with 1 frequency = £250 (VHF) / £1,000 (MF/HF) 1 station with 2 frequencies = £500 (VHF) / £2,000 (MF/HF) 2 stations with 1 frequency = £500 (VHF) / £2,000 (MF/HF)
Please note: The appropriate fee must accompany your application form.
Failure to do so will delay your licence being processed.
