The programmable antenna satellite amplifier Johansson 9780 is designed for direct distribution of TV electrical signals using coaxial distribution STA or for preparation - equalization and optimization of the frequency spectrum for the subsequent optical station for signal distribution using optical cables. The amplifier has four inputs in the 290 to 2340MHz bands, to which you can connect signals from satellite LNBs (qatro, quad or broadband). An auto-tuning mode is enabled, where all incoming transponders are copied from input 1 to output, or it is possible to select individual transponders from connected LNBs and frequency convert them with all parameters into one output band, which can be combined with terrestrial TV channels. The amplifier automatically reads and displays the signal level of the selected satellite transponder, which means that you do not need a measuring instrument for setting.
The Johansson 9780 antenna satellite amplifier is suitable for use in hotels, boarding houses, apartment houses where foreign visitors are accommodated, as it allows you to select up to 32 transponders from 4 different satellites (using broadband LNBs), convert the frequencies of these transponders to another frequency suitable for distribution in one IF band in a common television antenna.
The output of the Johansson 9780 programmable amplifier can be combined with the output of the terrestrial program amplifier, eg Johansson 6700 with the Johansson 9501 combiner. Examples of use can be seen in the leaflet, which can be downloaded from the website of TIPA spol. s r.o.
