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.
