You can use the MR 2-way splitter to divide the signal output from your repeater and feed two indoor coverage antennas. You can purchase additional cables to connect your indoor antennas.
The most popular style of indoor coverage antennas for applications with splitters are the MR omni-directional celiing mount antennas, which can be found here. Installation involves connecting the splitter with a short cable lead to the input of the splitter.
The two signal outputs connect with cable to the indoor coverage antennas.
