859957 700-2400MHz Signal splitter
The 859957 is a splitter which allows you to split the signal from a repeater over 2 or more internal antennas.
The coverage area of each antenna will be half of the coverage area of a single antenna, which equates to 70% of the coverage distance.
This is useful if you wish to improve signal in 2 separate locations, or on 2 separate floors.
Cellular repeaters typically only improve the signal on the floor that they are installed, so the splitter is useful for those with multi-leveled homes. If this is your situation, you may like to purchase the add-on antenna kit.
