When buying a satellite amplifier, it is important to understand the specifications that differentiate one amplifier over another. This will help determine the model or type of amplifier needed to meet your needs.
Every satellite amplifier will operate within a specific decibel range. This measurement refers to the average noise produced when using the satellite amplifier. Keep in mind this does not mean that the sound coming from the broadcast monitor or television will be amplified. It simply refers to how much sound is transmitted from the satellite antenna through the amplifier.
The gain of the satellite amplifier will also be displayed as db. This is referring to the ration or output to input power. Amplifiers with a higher gain setting are more sensitive and will require a lower strength signal to produce the power needed. Gain settings are also related to the amount of space between the antenna and the device. If there is more than 100 feet of space, a satellite amplifier with a higher gain should be used. High gain settings are not required when the amount of space is 50 feet or less.
The frequency is measured in MHz and the amplifier will have a stated range that it will operate within. The frequency range represents how well the amplifier will receive signals from the satellite. The more frequency range the satellite amplifier has, the more effective it will be at increasing the strength of the signal. Since satellites operate on different bandwidths, having an amplifier with a wide frequency range will be more effective in receiving signals.
