Introduction
Standards and deliverables of EN 60728 series and EN 50083 series deal with cable networks including
equipment and associated methods of measurement for headend reception, processing and distribution of
television and sound signals and for processing, interfacing and transmitting all kinds of data signals for
interactive services using all applicable transmission media. These signals are typically transmitted in
networks by frequency-multiplexing techniques.
This includes, for instance:
a) regional and local broadband cable networks;
b) extended satellite and terrestrial television distribution systems;
c) individual satellite and terrestrial television receiving systems;
and all kinds of equipment, systems and installations used in such cable networks, distribution and receiving
systems.
The extent of this standardization work is from the antennas and/or special signal source inputs to the
headend or other interface points to the network up to the terminal input of the customer premises
equipment.
The standardization work will consider coexistence with users of the RF spectrum in wired and wireless
transmission systems.
The standardization of any user terminals (i.e. tuners, receivers, decoders, multimedia terminals etc.) as well
as of any coaxial, balanced and optical cables and accessories thereof is excluded.
This document introduces the requirements for DTT filters with stop-bands for the 700 MHz and 800 MHz
bands. These filters are for use in individual and MATV antenna installations for reception of DTT signals
when the 700 MHz band will be used by telecommunication services in addition to the 800 MHz band.
These requirements extend those of CLC/TS 50083-2-3 for mitigation filters for LTE services operating in the
800 MHz band only and ETSI EN 303 354 V.1.1.1 (2017-03), that deals with “Amplifiers and active antennas
for TV broadcast reception in domestic premises; Harmonized standard covering the essential requirements
of article 3.2 of Directive 2014/53/EU”. The ETSI document is mainly applicable to new equipment available
on the market, while this document has the purpose to allow the existing individual and MATV antenna
installations as well as amplifiers designed for the full spectrum of band 4 and 5 for reception of DTT signals
to avoid or mitigate the interference due to the new telecommunication services when the 700 MHz band is
added to the 800 MHz band already used.

These DTT filters are not designed to be used for CATV networks.
1 Scope
This document provides requirements for passive filters intended to reduce RF interference from mobile
Base Stations (BS) and User Equipment (UE) to receiving equipment and master antenna cable distribution
systems of broadcast DVB-T and DVB-T2 signals in the VHF and UHF bands. While primarily intended to be
used with VHF/UHF DVB-T and DVB-T2 receivers and signal distribution systems, filters can also be useful
for mitigation of interference to VHF FM or DAB radio.
