All of these Amplifiers will Pass HDTV, DTV and Analog Signals. Those that have a Specific Band-Pass of up to at least 890 MHz are good for VHF/UHF and FM also... Making Them Suitable for Home use of Off-Air Antenna Television Carriage.
NOT suitable for Satellite, or broad band cable internet.
All these Amps are forward only (54-890 MHz, 50-900 MHz), matching the Bandwidth of any TV Antenna System, but will not pass return from High Speed Internet Modems or Pay Per View Converter Boxes associated with Cable TV signals. For Satellite Carriage you will need an Amp with a Frequency between 950 MHz to 2150 MHz.
Amplifiers- Should be utilized for these two reasons:
1.) To increase already adequate signal as to pre-emphasize the level to balance out losses after the amplifier such as splitters and cable in the distribution system on its way to various TVs in the house, and
2.) 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.
Do I need an amplifier with an adjustable Gain?Choose a model with an adjustable Gain control, so you can find that sweet spot and save (in reserve) some gain for future additions and signal Splitter, or balance the amplifier out to feed another amp at the other end of a cable segment to extend your systems reach to another building.
Do I need a distribution Amplifier? Check Your Picture quality where the Cable TV feed enters your Home, if it's good there, you can replace connectors, cable and Splitter to bring your installation up to the newest specifications. If you are feeding numerous TV sets or long Distances, use one of these Amplifiers before the Splitter Or long cable run to maintain Signal Quality.
Digital Signals don´t need to be high to get a picture.
Amplifiers come with various gain numbers. Old Analog signals needed a high Carrier to Noise to get a high Signal to Noise Ratio of the Picture on your TV set, it was a one to one relationship and more was sometimes better. Digital Signals are lower in amplitude in comparison to Analog (a benefit) and that commensurately, the threshold at the TV is lower for a perfectly good picture. Very little in between, you either get a good picture or you don´t. Snow in the old analog pictures has been replaced by "Tiling" or little blocks within the picture not keeping up with the scene changes in today´s Digital TV viewing. Tiling is therefore today´s Digital Snow. It means (more often than not) that you are not far enough above the threshold of signal level into your TV to prevent little hiccups, drop-outs and interferences in signal from interrupting the Stream of Data. Remember that lots of things can happen from the Station on the way to your TV set!
Selecting an Amplifier with the Proper dB Gain.
The gain of a Line Amplifier should be selected to zero out the loss that follows it. In other words, if you have fifty feet of cable and a two-way splitter, then a 10 db amplifier will be fine. Conversely, if you have an eight-way splitter and hundreds of feet of cable, you will need an amplifier with a higher gain. Just as in the case of a Pre-Amplifier, however, bigger is not always better.
