How a Cell Phone Network Signal Amplifier works


The outdoor antenna receives and transmits signal to nearby cellphone towers. Outdoor antennas be either directional or omni-directional.


The amplifier (or "repeater") boosts the signal coming from and going to the cell phone tower. The "gain" of the amplifier describes how strong the amplification is - you'll see that word scattered across our product pages.


The indoor antenna rebroadcasts the signal inside the building. Some kits have more than one indoor antenna to help distribute the signal.


Q: Is this model of Cell Phone Network Signal Amplifier suitable for a 3500 square feet house?

A: Yes, but you will need additional indoor antennas and splitters to get the signal distribution throughout the interior of the house. For a big house, the coverage will also depend on the signal strength that you are getting outside and how far you need to run the cable to the house. If you have a solid 4-5 bars outside, then you can get bigger coverage indoor after installation. If you get 2-3 bars, then the coverage will be smaller.


Q: Can the Cell Phone Network Signal Amplifier work inside without the external antenna?

A: Cannot. Since the booster is supposed to boost the mobile signal due to obstructions, such as constructions, trees and tall buildings etc, the external antenna must be located outside your home where has good signal reception. The external antenna catches good signal and transmit to the signal booster, the signal booster amplify the signal and transmit to the indoor antennas, and the indoor antenna will broadcast the signal to your mobile phones.


Q: What does “Db” mean in the Cell Phone Network Signal Amplifier description?

A: Decibel is a unit of measurement showing the strength of the cell signal. One bar or dot on your phone to 5 bars or dots is equivalent to about -80 to -120 DB loss from the original transmission where -80 is good, less loss, and -120 is weak or bad from great loss.


Q: Will the Cell Phone Network Signal Amplifier work with a Samsung cell phone?

A:  The booster will work regardless of cell phone type, as it relies on the carriers signal. As long as you can make and keep calls outside, the booster will work. It boosts the carriers signal. Type of mobile device is irrelevant.
