![]() ![]() They are generally the best choice, as they are guaranteed to work with your setup.Ī bi-directional amplifier generally contains components of its own: Finally, wideband amplifiers boost all 4G and LTE signal in an area at a slight cost to overall power. Dual-band amplifiers focus either on two specific bands used by a carrier, or across all 3G bands (these are being phased out of production rapidly). Single-carrier amplifiers boost all bands used by a given carrier. There are several types of amplifiers, each of which function slightly differently:Įach of these are designed for a different purpose. This is the centerpiece of every system, and what provides the increased reception you are after. The most important part of a cell phone repeater is the bi-directional amplifier. More powerful systems can have numerous donor and rebroadcast antennas depending on the need of the building they are installed in. These components have numerous arrangements based on the power of the amplifier and the desired result. These three components are installed in order to maximize coverage indoors. The rebroadcast antenna(s) then retransmit this amplified signal locally. The outdoor antenna(s) is connected via coaxial cable and connectors to a repeater (or amplifier) unit, which amplifies the signal. These can be scaled from low-power units covering the inside of a car to large active distributed antenna systems (DAS) covering large stadiums. ![]() ![]() A cell phone repeater is used to bring signal from outdoors inside a structure or vehicle, bypassing building material that harms radio frequency (RF) waves. ![]()
