With a very long and difficult to pronounce name, Diplexer Satellite Combiner & Splitter is a marvel of electronics, it is a divider and mix of RF combining satellite antenna + DC + local terrestrial antenna digital (VHF UHF HDTV CATV TV ) on a single cable without interference or other problems. The Diplexer Combiner, as it is called, has two entrances, one to the antenna ANT Local VHF and UHF, another SAT for antenna TV, and I / O output with the two mixed signals.
Satellite Dish Antenna and common in one cable
The name comes from Diplexer Duplex , which means double , equivalent to twice or that replicates the service, which operates in two modes or two systems or a communication system consisting of two points that communicate with each other in both directions , at our case are RF signals that are mixed and then separated . This mixer is the lifeline for small spaces , long distances or where the wiring will not support another cable . You can use the same coaxial cable already installed to pass the RF antenna of the local terrestrial and satellite signal + DC together.
Using diplexers (two crossovers ) the main benefit is to use only one coaxial cable, so a reduction of spending on materials and workmanship . The Diplexer Combiner supports a satellite dish , or an LNBF to Receiver C Band or Ku band. It is capable of supporting systems FTA ( Free to Air) as well as C-band KU band , Digital receiver , Analog Receiver , cable TV operators DirecTV , Sky , Via Embratel , Hi , Vivo , Telefonica , among others .
There are hundreds of manufacturers Diplexer but little difference in the electronic issue between him , is more on the mechanics they differ . Most have an antenna input ( ANT ) which can be VHF - UHF - HDTV - CATV , which has a frequency range of 5 MHz to 850 MHz , since the input to satellite dish ( SAT ) has a frequency range of 950 MHz to 2400 MHz ( varies from manufacturer ) . The maximum DC current passing is 500 mA , the loss of RF signal from the satellite avg 3 dB and the impedance is 75 Ohms .
How to Install Satellite TV Diplexer
The installation and operation of the Diplexer Sat TV is quite simple, you should always use two antennas Diplexer one along to mix the signals of the satellite dish antenna and common, and another near the TV and satellite receiver to separate the RF signals. It supports other components in the antenna, including the keys to high frequency multipoint LNBF and mixers VHF and UHF signal Places antennae system.
It is advisable to protect the Diplexer time, especially rain, although toasted and weatherproof, a small water infiltration can cause damage and losses in the RF signal. When installing crossovers let the satellite receiver off. This system is compatible with all satellite receivers analog and digital KU and C band
