3. How does KW19L Tri-band mobile signal booster work?

Actually, with only one device of KW19L tri-band mobile signal booster it cannot work, the supporting accessories are necessary. A system of signal booster includes the host KW19L ri-band mobile signal booster, an outdoor antenna, an indoor antenna, length-customized cable. And if you want to cover much more areas, maybe you need several splitters to realize it connecting multiple indoor antennas. Then here I can introduce the working principle of KW19L tri-band mobile signal booster:

1. Find a place where better with 4-bar cell phone signal receipt outside of the building.

2. Install outdoor antenna at the site with better signal receipt. And outdoor antenna should be better pointed to the base station.

3. Install KW19L tri-band mobile signal booster inside and use 15m cable to connect the booster with the outdoor antenna. Caution: there should be isolation between the booster and the outdoor antenna, without the isolation (like wall), there would be an effect named self-interruption to obstruct the system.

4. Finally, use cable to connect with KW19L tri-band mobile signal booster and indoor antenna.

Then turn on the booster to test the working function. If there is any problem about the device, pls call Lintratek after-sales team for help.
