Coaxial arrestors come two types:
With either gas-discharge protector and Lambda/4
technology. For example, no
Wi-Fi signals according the 802. For signals outside the frequency range sup-
ported, this arrestor type galvanic short circuit.11n standard with
a frequency 5.
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.9 GHz can transmitted. These arrestors are band-pass
filters that only pass frequencies within specific
range. Due to
the capacity the gas-discharge tube they are
however limited their bandwidth: the cut-off fre-
quency currently around GHz. The gas-discharge tube
can additionally replaced case defect.
These offer optimal transmission behaviour with low
damping values and are connected series the
transmission path.

. They are available for virtually
all plug systems.
Coaxial surge protective devices with gas-discharge
protector
The first type coaxial surge protective devices with a
gas-discharge tube.
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. They can therefore used a
wide range applications.
Suitable arrestors for these applications include the
DS coaxial surge arrestor from OBO Bettermann. These enable transmission from a
frequency (DC). They are available for all standard
connections
