The power Inserter in this package can be connected to your existing cable wiring at the cable box! this will allow you to view your HDTV Antenna Signals throughout the whole house just like you did with your cable! This preamplifier will amplify the VHF/ UHF (ANTENNA) signal before any signal loss occurs and the 2nd amplifier will increase the signal strength so it can be distributed through the existing cable wiring! This amplification is necessary when a signal is sent through long lengths of cable (50 ft. or more) or when the original signal is too weak to produce a good picture at the receiving unit (TV/monitor or TUNER). Do you have missing channels, weak or pixelated pictures? You could have signal loss due to the length of cable or due to the number of splitters you are using. Insert this amplifier into the coaxial line near your antenna or signal source. This Amplifier can help you receive those channels that are to weak if your in a rural area and over come long run signal loss. COMPATIBLE WITH ALL HDTVs Quantities Are Limited So Order Yours Today!
