The SPS-2051-I Power Inserter 5-1000 MHz with 20 VDC 500 mA  Power Supply .Provides power for LNB or Inline Amplifiers and also provides power for MMDS Down Converter and Amplifiers.

When Splitting the High Frequencies of Satellite TV Services to feed multiple Receivers, the Loss associated with the splitter may need to be compensated for with the use of an In-Line Satellite TV Drop Amplifier (Signal Booster) specific to this purpose and Frequency Range. Consider the need and review the "Satellite TV Amplifier" category for selection. Most of these Satellite In-Line Amplifiers are line powered from the Satellite Receiver and will not, under most circumstances, require any externally coupled supply that this is intended to couple. If the receiver doesn't inject DC power for use by LNB(F)'s, or the segment of cable you need to amplify doesn't have DC Voltage on the line at that point, and you need to install an In-Line Amplifier there, this is the means to get power on that line!

This Power Inserter will pass Frequencies also associated with Cable TV and TV Antenna use. TV Antenna Preamps usually include a Power Supply and Inserter, if you need an Inserter/Power Supply Combo for this purpose, this one will do.

Most In-Line Cable TV amplifiers also come with the aforementioned accessories, but if you are missing them, this Inserter/Power Supply Combo will also fit the Bill.

If you need to block the DC voltage from passing on either side of the Amplifier, use the VBC (Voltage Blocking Coupler, which is a separate item) to block the DC voltage from passing to other devices and prevent damaging them!

Commensurate with Coaxial Cable TV Antenna and Satellite TV Power Inserter Installation, you want to Ground your Cable TV or HDTV Antenna Coaxial Cable System Outside before bringing the TV Cable Inside. This way, Lightning Strikes and Power Surges have an opportunity to arrest before reaching your Satellite Receiver and TV Set(s). The Integral Grounding Block designed onto most Outdoor Use Compatible Satellite Signal Splitters and Inserters we sell will effectively convey this unwanted Electrical Energy to a Ground Rod via a Copper Ground Wire that you Install (not included). Consult your Local Building Code and NEC for guidance to Properly Grounding your HD TV Antenna, Satellite TV, Cable TV, WI-FI, Wireless Internet, Business Band, CB or Amateur Radio Antenna Installation.
