The VHF/UHF/SAT Diplexer Nanosat, ESP22A1 model, can be used in two ways:
- To mix the signal of VHF/UHF the same satellite coaxial cable.
- To separate the signal of VHF/UHF satellite and comes in a single coaxial cable.
The terrestrial TV signal on VHF and UHF frequencies for use 54 MHz a 806 MHz (channel 2 the VHF channel 69 the UHF). Satellite TVs utilize microwave frequencies, but the LNB (that is the antenna) converts these higher frequencies for ranges between 950 and 2150 MHz. It is possible that both signs share the same cable.
This cable is sharing interesting in situations where you cannot pass separate cables for cable and satellite TV. At VHF/UHF/SAT Diplexer Nanosat can be used with the antennas to mix the signal. Enter a cable coming from the(s) antenna(s) VHF/UHF and the other coming from LNB satellite TV antenna, a cable with the two signals combined.
The VHF/UHF/SAT Diplexer Nanosat also serves to separate the signals with the decoders, TVs and receivers. In this case enter the signal mixed and out two separate cables, with the signal of VHF/UHF and the other with the satellite TV signal.
In an example of use, You can use the Switch 3 × 4 Nanosat NS34ST or a VHF/UHF/SAT Diplexer to combine the signal along to antennas, and then use a VHF/UHF/SAT Diplexer Nanosat next to each TV to separate VHF/UHF signal to be connected to the TV and the satellite signal to be connected to the satellite TV decoder.
Even those using separate cables for VHF/UHF and satellite TV might need a VHF/UHF/SAT Diplexer for mixing the two signals and connect them in a single entry of the satellite TV decoder, If this decoder also tune in Digital Terrestrial TV channels. This is the case of the new Sky decoders, SH26 and SHR26. So they tune the Digital Terrestrial TV channels the UHF signal is mixed on the same cable.
Importantly, the VHF/UHF/SAT Diplexer Nanosat Let the direct current required for the decoders of satellite TV feed the LNB which is next to the antenna. The current passes only the combined input/output to the input/output of the satellite signal. Input/output of VHF/UHF is isolated, so that the chain does not go to the VHF/UHF antenna to the antenna input of the TV or digital terrestrial TV receiver.
The mixed signal should never be connected directly to a TV or digital TV receiver on their own may not be prepared to filter this current that accompanies the satellite signal. You must use a VHF/UHF/SAT Diplexer Nanosat or a current filter.
The loss by inserting the VHF/UHF/SAT Diplexer Nanosat is ≤ 2,0 DB in VHF/UHF and ≤ 1,5 DB in satellite signal.
