These enable transmission from a
frequency (DC).
These offer optimal transmission behaviour with low
damping values and are connected series the
transmission path. They can therefore used a
wide range applications. The gas-discharge tube
can additionally replaced case defect.
Suitable arrestors for these applications include the
DS coaxial surge arrestor from OBO Bettermann. For signals outside the frequency range sup-
ported, this arrestor type galvanic short circuit. Due to
the capacity the gas-discharge tube they are
however limited their bandwidth: the cut-off fre-
quency currently around GHz.
Surge arrestors with Lambda/4 technology
The second variant the surge arrestor with
Lambda/4 technology.11n standard with
a frequency 5. For example, no
Wi-Fi signals according the 802. They are available for all standard
connections.TBS

Chapter The internal lightning protection system
. Coaxial arrestors come two types:
With either gas-discharge protector and Lambda/4
technology.9 GHz can transmitted.
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.
Coaxial surge protective devices with gas-discharge
protector
The first type coaxial surge protective devices with a
gas-discharge tube.
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. These arrestors are band-pass
filters that only pass frequencies within specific
range. They are available for virtually
all plug systems
