Satellite TV Amplifiers

20 db Gain Wide-Band In-Line

An In Line Amplifier can be a great help in distributing TV signals especially if you have to power a number of separate receivers throughout the home. Although satellite television signal is able to provide a great volume of information at a remarkable speed – video, audio and even internet service can be transferred – the amount of data contained within the signal does not matter if the signal is too weak to be read when it arrives at its destination.

With an In Line Amplifier incorporated when installing any satellite television network you can help improve overall signal strength. By following the measures outlined in this article you will be able to ensure that all data transmitted between your satellite TV equipment does so in the most efficient and reliable manner possible.

Signals transmitted across coaxial cable on your satellite network have been added to a carrier wave at a fixed frequency. This wave also has a power level called its amplitude. If this level drops too low, the signal will not be readable when it reaches its destination.

One of the best ways to keep a signal at the required amplitude is by installing an in line amplifier such as the relatively inexpensive Eagle Aspen SA-2050+ 2150 Mhz In-Line Amplifier. These devices attach to the network using a simple F connector directly to the receiver or satellite dish. The other end connects to the coax cable. See Product Features…

An alternate product is the RCA In-Line Amplifier For DirecTV. It is important to note that an in line amplifier will amplify not only the signal, but also the noise present on the cable. Therefore, it is important to ensure that your cables are well shielded, that their connectors fit securely, that there are not excessive sources of electromagnetic interference nearby and that the cable run is as short as reasonably possible. All of these factors can affect the amount of noise in your cable run. See Product Features…

Alternatively, you can use smart in line amplifiers. These are often referred to as repeaters or signal boosters for example the Motorola Signal Booster Bi-Directional RF Amplifier. The circuitry inside these devices reads the data from the carrier signal, ignores any noise, amplifies the data and retransmits it at a higher power. They require more power and are more expensive than dumb in line amplifiers. See Product Features…

Typically, the best choice is to avoid having to use amplifiers in the first place. Carefully plan your cable runs before you begin doing any physical work. Run your wires away from major interference sources and keep them as short as possible.

In addition, you can also use satellite equipment that transmits at a higher power level. See the manufacturer’s specifications to learn what output amplitude it produces. This documentation might also show the minimum input amplitude the devices are sensitive to.
