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.

1. Coverage up to 1000 m²
2. ALC Function
3. Simple in connection and installation
4. An optimal cooling with aluminum shell
5. Led indicators show working status and ISO alarm.
Support any cellular devices (voice & data & video)
1. After installing booster signal not be very good, indoor signal coverage very small ?
> Adjust outdoor antenna's location and direction
> Change another high gain outdoor antenna
> Check whether cables are connected well
> Change more powerful repeater
2. Cell phone signal full bar, but communication quality bad ?
> Much closer distance between indoor and outdoor antenna, separate them with a longer distance.
3. After installing booster not only signal be good, but also more bad ?
> Much closer distance between indoor and outdoor antenna, separate them with a longer distance.
4. Working good for long time, suddenly signal bad ?
> Check whether outdoor cable connectors are flooded
> Check whether power light is working normally
> If cables are not flooded and power light is working normally, the booster should has problems and need to be sent back to factory for repair.
Installation:
The booster is fixed onto the wall through expansion bolts.
A. Drill holes on the targeted place and install expansion bolts.
B. Align the holes with the expansion bolts, place flat washers, spring washers, and nuts in turn, and tighten the nuts to fasten the installing support.
C. Place the booster on and fasten it.
D. Connect cables and power cables to the booster respectively.
E. After installing the booster as described above, power on the booster to check the operation status.
