DEHNsecure surge arresters
Innovative mobile radio systems rely on remote radio heads:
the high-frequency signal is directly generated at the an-
tenna and is then transmitted. Optical fibre cables, which
have significantly higher transmission ranges than conven-
tional coaxial cables, transmit data between the remote
radio heads and the base station. The remote radio heads
are supplied by a separate 48 V dc line. Operators as well as
power supply manufacturers rely on DEHNsecure dc
lightning current arresters.
DEHNgate high-frequency arresters
High-frequency arresters such as DEHNgate are used to pro-
tect radio transmission technology based on conventional
coaxial high-frequency cables, for example in GSM railway
systems or digital radio systems of security authorities.

DEHNrapid LSA arresters
DEHNrapid LSA lightning current and surge arresters are
used in service area interfaces for land-line connections or
the transmission of the sending signal of microwave links
over the last mile.
