Foreword
This European Telecommunication Standard (ETS) has been prepared by the Transmission and
Multiplexing (TM) Technical Committee of the European Telecommunications Standards Institute (ETSI).
This ETS specifies the minimum performance parameters for analogue radio relay equipment operating in
the frequency range 24,25 GHz to 29,50 GHz. The minimum performance parameters for digital radio
relay equipment operating in the frequency range 24,25 GHz to 29,50 GHz are given in ETS 300 431 [10].

Date of latest announcement of this ETS (doa): 30 June 1997
Date of latest publication of new National Standard
or endorsement of this ETS (dop/e): 31 December 1997
Date of withdrawal of any conflicting National Standard (dow): 31 December 1997

1 Scope
This ETS covers the minimum technical requirements for terrestrial analogue radio relay systems
operating in bands in the frequency range 24,25 GHz to 29,50 GHz.
Such systems are intended to be used for Point-to-Point (P-P) connections and video distribution
(Point-to-Multipoint (P-MP)).
Typical applications include:
a) TV of contribution quality;
b) TV of distribution quality;
c) TV of surveillance quality;
d) Radar remoting.
Safety aspects are outside the mandate of ETSI and they will not be considered in this ETS.
The requirements and limits given in this ETS are relevant to all environmental conditions for the chosen
climatic class.
2 Normative references

normative references are cited at the appropriate place in the text and the publications are listed hereafter.
For dated references, subsequent amendments to, or revisions of, any of these publications apply to this
ETS only when incorporated in it by amendment or revision. For undated references, the latest edition of
the publication referred to applies.
