The 859957 is a splitter which allows you to split 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 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.
Allows you to use 2 internal antennas with a single repeater. Covers the frequencies 700-2400MHz
