This is a brand new, four (4) port cable television drop amplifier, just like the ones that your local cable company uses to correct their system's shortcomings. It boosts signal strength by more than 5 x ( 7dB), Improves Analog, Digital and HDTV Picture Quality, and Improves UHF/VHF/FM Antenna Reception! The unit can be used with Cable TV, OTA Antennas (Analog or Digital as long as they are non-amplified). This model packs a powerful punch in a compact, easy-to-install package! If you have multiple televisions or run a cable modem for your internet, this product is recommended. By connecting this signal booster to the cable drop coming in from the street, you can increase the signal strength and eliminate the need for additional splitters, which reduce signal strength. If you are tired of tv pictures that don't seem as clear as they should be, dropped internet connections, or just desire a reliable amplifier to give continuous, steady signal to your home or business, this is for you! The latest Antronix MicroAmp provides exceptional home signal amplification in a small convenient package. Our patented CamPort provides the only auto-seizing F-port for maximum contact area and reliability for multimedia applications. Ideal for both indoor and outdoor applications, the MRA was engineered to withstand the harshest environmental threats with the capability of enduring repeated high power surges.
