If you need to Add a couple of HD Ready TV sets to your Cable TV Hook-up, this amp will do fine to Offset the Loss encountered when adding a splitter to feed the additional Outlets. It is extremely dependable and inexpensive to run. It is Forward only (54-1000 MHz), which matches the Bandwidth of any Cable TV System, but will not pass return from High Speed Internet Modems or Pay Per View Converter Boxes. We have Amplifiers that will do that... See Below! The Cable TV Company will be happy to Charge you to go through and Re-Install your Home, or you can do it yourself! With HD Digital Signals, the Signal Level is actually lower than the analog, and with increased Channel Capacity, not enough is there to feed your Home. Check Your Picture quality where the Cable TV feed enters your Home, if it's good there, you can replace connectors, cable and splitters to bring your installation up to the newest specifications. If you are feeding numerous TV sets or long Distances, use this Amplifier before the Splitter or long cable run to maintain Signal Quality. If the Picture quality is Poor at the Feed point of your House (the Cable Company usually has a gray box used as a Demarcation Point for this Purpose), call your Cable TV Technician and Demonstrate to him your issues, so he can effect repair.
Pre-Amplifiers are mistakenly used with the rational that it will bring in Stations that weren´t there before... It won´t, and what´s worse, using the same antenna and pre-amp with FM and TV stations close by (0-30 miles) may overdrive the amp and actually impede your ability to provide goods signals to your TVs. If you desire to use a pre-amplifier, don´t use a high gain when you have local stations, get one with a FM trap to keep FM radio stations from over-driving the amp and remember that today´s Digital Signals don´t need to be high to get a picture. Some Pre-amps come Band Selective as well, realizing that the difference in antenna UHF/VHF gain means that one band needs to be amplified as opposed to the other. Use them to maintain Signal level to noise at the origin (your antenna) so that low signal levels from far away stations are not lost in a longer than average cable run to the location in the house where the signals would be further distributed to the TVs desired.
