Dome Antennas are more popular because they project signal in all directions. Therefore, they are good for mounting on ceilings in central locations to project reception in 360 degrees fashion covering large square spaces.
Panel Antennas project signal in single direction. Therefore, they are good for installing on walls to cover rectangular areas like long corridors. They can be installed on ceilings to boost reception over multiple floors as they project reception downwards across multiple floors.
How does a signal booster work ?
Firstly, the cell phone reception is captured by the outside antenna. It is then amplified by the cellular repeater and rebroadcasted across the building or car through the inside antenna. The result is a boosted cell phone reception that culminates in more bars in your phone even in the remotest of places. You can then enjoy clearer calls (you won’t drop calls again) and faster internet browsing and rapid data downloads and uploads. This is how the cellphone signal booster works in your car or house. This is how all signal boosters work on all technology platform networks.
Introduction:
Signal Booster CKJ-20D-V is designed to enhance and improve the quality of mobile DCS 1800MHz connection. There're black and white colors for options. The Led Indicator will show the current level of the input signal, which simplifies the installation of the external antenna. High quality aluminum shell provides an optimal cooling. This model, as simple in connection, installation and configuration, does not require special skills.
