With the TechniSat Universal SCR 4 + 4 LNB, we have tested a particularly flexible receiver head for the satellite system, with which four participants can be supplied via Unicable EN 50494 via just one antenna line and four participants can be supplied in the classic way via four legacy connections. With the flexible combination LNB, which costs 96.50 euros, it is child's play to fully enjoy twin or quattro tuners to record a program and watch another or even FBC tuners can be fully used to the to increase parallel freedom of recording almost to infinity.
Thanks to the flexible features with a Unicable and four legacy terminals of the universal SC 4 + 4 LNB is not when using
multi-switch needs more
. In
unicable mode , each participant / tuner is assigned a frequency (user band). We show how this works and what they are in our detailed review. Everything else about the connections and the configuration can be found in our detailed test report. In it, we also give an example of a possible use or cabling of the LNB in connection with connected receiving devices with and without
Unicable support using a clear diagram .
The LNB has a
40 mm feed receptacle ,
LTE shielding , a low noise figure as well as
removable weather protection and a
degree scale for the skew angle . We took a close look at how these features are implemented and how the LNB can be handled in practice and what value the material processing shows in our detailed test.
Test environment and reception values
Whether the combined LNB was able to convince in the reception test is shown in the test report using clear graphs that record the reception level, the C / N value and the VBER / LBER value. We tested the LNB at the orbital positions Astra 19.2 ° East and via Hotbird 13 ° East, Astra 28.2 ° East and Thor 0.8 ° West with the
Fuba DAL 800 (80 cm reflector diameter) and with our professional measuring device
Promax TV Explorer HD . We recorded over 1,000 measured values. We present the results and the evaluation of them in our extensive practical test. What to consider when aligning and how the frequencies for the user bands in receiving devices such as the DVB-S2 receiver
TechniSat UHD S and the Linux satellite receiver
Dreambox One Ultra HD will be assigned step by step.
