They are available for all standard
connections.
These offer optimal transmission behaviour with low
damping values and are connected series the
transmission path. The gas-discharge tube
can additionally replaced case defect.
The advantages this technology are its support for
frequencies around GHz, and its very low
protection level approximately They also re-
quire virtually servicing because they not use a
gas-discharge protector.

These sensitive, high-frequency systems need be
protected from lightning currents and surge voltages. For example, no
Wi-Fi signals according the 802.9 GHz can transmitted.

Suitable arrestors for these applications include the
DS coaxial surge arrestor from OBO Bettermann. These enable transmission from a
frequency (DC).
The disadvantages these devices are that not
possible transmit supply voltage along the sig-
nal line, and their scope application generally lim-
ited just one application, depending whether the
necessary frequencies lie within the frequency range
supported. For signals outside the frequency range sup-
ported, this arrestor type galvanic short circuit. They are available for virtually
all plug systems. Due to
the capacity the gas-discharge tube they are
however limited their bandwidth: the cut-off fre-
quency currently around GHz. Coaxial arrestors come two types:
With either gas-discharge protector and Lambda/4
technology.11n standard with
a frequency 5. These arrestors are band-pass
filters that only pass frequencies within specific
range.
