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.

Interesting. Never had satellite TV, but by your posts it seems that it's complicated. The cable is only connect the cable to the receiver and the hdmi on TV without worrying about anything else.
Yes, on cable is simpler because it can target more, including the sign of all the affiliates sites, practically eliminating the open terrestrial TV signal. Furthermore, her cable cannot be shared, since they already use all the viable spectrum by default. But who wants to use terrestrial TV is also some complications, for example:
I'm ready for cable wiring, Terrestrial and satellite TV in my house. Just not counted with a second cable to the Sky HDTV Plus, that had to be passed recently. Don't use any multiplexing. The cable TV wires are stranded because no operator goes through here yet.
Formerly the NET allowed the analog channels open, but there's nothing else analogue, just pops up a picture saying that need to use the decoder. I was still at the time that all channels were analog cable, and they put a filter to block the channels outside the package hired, that could be easily bypassed.
It is curious that my TV tune TV channels open digital cordless. The external HD that is hanging from a USB near the entrance to the tv cable acts as an antenna, and the picture is perfect with various channels tuned. If you remove the hard drive does not work. Must be some interference of chain that feeds the HD. The good thing is that if I want to use the TV, to use PIP or the writer of the TV itself, I don't need another cable to tv.
And the decoder of the NET that tunes over a channel, to record one and watch another at the same time, It does this using a cable only, understanding hair, the SKY need 2 cables.
The Net here, at least until a few months ago, still had some open channels in analog. Also remember the filters, When I signed the Net in another House a few years ago still put the filters, because there were some closed channels in analog. Even used a splitter and called the Net so much on TV and decoder, even some in the analog channels that I would take my digital package (super-básico, Since I only used the Internet and the phone and had the Sky to TV) wouldn't start. Digital TV here just caught with external antenna even. But who lives in building can even tune just sticking a open Clip on cable entry. The Sky need two cables because the universal LNB or only sends broadband polarization channels horizontally or vertically at a time. So to tune a channel for each polarization it is necessary to have two cables. The LNB STO circumvents this limitation, but no longer use it. They must have other LNBs that could work with a cable only, but I guess you can't put all the channels at the same time in the range of 950 ~ 2150 MHz. It is curious that the Net use… Read more »
Interesting, I thought this frequency band Division was the analog signal. And the digital work as a local network with servers on the net, as a super fast streaming. If it's all in the range of frequency and the signal of every channel comes at the same time on the cable, I find it interesting how it fits so many channels, whereas the PPV and still have room left over, because the Olympics the SportTV will have 12 HD channels. Not long ago entered 2 HD Interactive sports channels, namely, usually add channels.
The phone on the net at least should work together with the internet for Voip and not use own frequency range, because it is connected directly to the modem
Even on digital cable TV channels are still for broadcast. The advantage is that in the space of a single analog channel (6 MHz) You can place multiple digital channels SD channels (or at least a 2 HD). The problem is that sometimes compress too much to fit more and the quality is impaired. SD channels, both Sky as Net compress too much, Since the time that neither existed HD. The macroblocks and compression artifacts are visible. I think the situation tends to improve when the entire subscriber base is already migrated to decoders that support MPEG4/H. 264, because then you can finally leave the compression MPEG-2 SD channels, What will save a good space and improve the quality.
I am installing a digital tv and am using a diplexer to mix a digital tv signal and a satellite in every apartment I'm putting a diplexer, I have several dividers between them, to distribute the network in all apartments, My question is the satellite signal will pass through the dividers or have to be special about frequency dividers ? or the diplexer he mixes the digital tv signal more voltage to feed the LNB ? thank you
Have no experience with this, but theoretically will only work if at every exit of diplexers has a single satellite decoder. You can divide the signal digital terrestrial TV with dividers, but the satellite on the polarization. The diplexer terrestrial signal in (VHF, UHF) that covers all channels, with the polarization of the high-frequency channel that is being watched. So I wouldn't give for a decoder to be fine-tuning a horizontal channel and other fine-tuning a vertical channel for the same output of the diplexer. In each output of the crossover has a single satellite decoder and more of a TV to get digital terrestrial TV signal OK split, but the need to support high frequency dividers (Some filter signs above 900 ~ 1000 MHz) and on every TV must have a DC filter, otherwise the decoder sends voltage to the diplexer (to feed the LNB) will leak into the tv.
