1 Scope
The present document details standardized procedures for conformance testing of antennas for Point-to-MultiPoint radio
relay systems [1], [2] and [3] in order to achieve the approval by the Type Approval Authority.
The procedure for dealing with established products is outside the scope of the present document.
The present document is intended to be applied in conjunction with the individual antenna standards and will enable
commonality in the presentation of test results, irrespective of the Suppliers/accredited laboratory carrying out the test.
The conformance tests described in the present document are related to antenna specific parameters required directly by
the relevant antenna standards [1], [2] and [3].
The present document applies to both those antennas that are separate and those that are in some manner partially or
fully integrated with the outdoor equipment. In all cases, whilst facilitating access to the appropriate antenna port,
testing shall preserve the electro-magnetic environment i.e. be representative of the outdoor unit enclosure / electronics
used in the typical (manufacturers' recommended) configuration. This need to maintain consistency with the
manufacturer's recommended configuration is particularly important for less directional antennas (commonly with less
than 25 dBi gain, although this value will depend on the specific ETS/EN parameters for that class, type etc).
It is noted that antennas intended for Point-to-Point (P-P) use are similarly the subjects of separate standards covering
their characteristics and conformance testing [5], [6] and [7]. In some cases, particularly for the higher gains and
frequencies, such P-P antennas may be appropriate for P-MP usage at the discretion of the regulatory authority. In such
cases the regulatory authority will also define the applicable antenna and conformance-testing standard.

4 Requirements related to antennas conformance test
P-MP antennas may be designed for Central Station (CS), Repeater Station (RS) or Terminal Station (TS) use, and may
be categorized in the corresponding standard by means of type, class and range, as required [1], [2] and [3].
Some P-MP antennas require definition of the antenna zero degree reference, which is defined as the declared direction
as referenced to the antenna mechanical characteristics, and this is used as reference for the RPE.
Although the RPE limits for TS and some RS antennas are generally identical for azimuth and elevation, the actual
patterns should not be assumed to be symmetric.
4.1 General requirements
In table 1 the generic clauses and parameters are classified, for conformance test purposes, in terms of the various
categories. The table also provides for defining the climatic conditions applicable during testing of the parameters.
