The following reference tables, maintained by the Bureau, are designed to assist broadcasters and administrations in the preparation of their HF
broadcasting requirements and to provide a common code system. The use of common code system should facilitate coordination between
administrations, broadcasters and other users of HF spectrum.
Reference tables are in ASCII text format. They are used by all HFBC software
modules, therefore, it is important to update your Reference tables regularly!
Transmitting antennas for HF broadcasting
list including antenna codes and antenna definitions,
based on ITU-R BS 705. Here you will find
information concerning the most common antenna types and their parameters:
Curtain antennas, Tropical antennas, Lo-periodic antennas, Rhombic antennas,
Quadrant antennas, Cross-dipole antennas and Vertical Monopoles.
CIRAF zones maps
The CIRAF zones and quadrants are used specify the Target service area. The
agreed set of 911 test points is used by the HF software to
calculate strength values at each test point inside the required service area.
Authorizations for submitting HFBC requirements
Requirements are to be submitted by administrations or organizations who are authorized
by the administrations concerned to do so, such as
broadcasters and frequency managers. In the latter case, administrations are expected to
advise the Bureau in writing, in advance, stating the names of the authorized
organizations, their three-letter code for ease of identification and the scope of the
authorizations (see Article 12.1); otherwise the requirements cannot be accepted by the
