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