SPAUN FAQ Common Questions
» Is it enough to distribute only the High-Band Signal for digital reception ?
» Is my satellite-system for ASTRA 19,2 East fit for digital reception ?
» Which cable lengths can be used ?
This question cannot be generally answered. However, there are factors that must be considered in principle and based
on these factors it is also possible to determine whether a desired cable length can be realized or not.
For the calculation the following specifications are needed: The attenuation of the used coaxial cable at 2000 MHz. A
typical value for a standard 7mm coaxial cable is approx. 30dB/100m. SPAUNs SPOAX cable is a high quality cable
and has an excellent attenuation of 27.8 dB/100m at a frequency of 2150 MHz. Furthermore, the signal level from the
LNB is required (typically 78 dBV). Finally, the technical specifications of the used multiswitch are needed to do the


The LNB provides a signal level of 78 dBV. The distance from the LNB to the multiswitch (SMS 51603 NF) is 30 m.
This cable length indicate an attenuation of approx. 9 dB. Therefore the input level of the SMS 51603 NF should be
approx. 69 dBV. The SMS 51603 NF has a gain of 9 dB so we can reach an output level of 78 dBV.
The signal level at the sockets should be at least 55 dBV. This means that we have a signal budget of 78 dBV - 55
dBV = 23 dBV. A budget of 23 dBV is equivalent to a cable length of 70m and additionally the used TV socket outlet
(ASE 5 F).
