A splitter allows you to evenly split the boosted signal between 2 to 4 indoor antennas. They are commonly used when multiple indoor antennas are needed to achieve desired coverage. There are 2-way, 3-way, and 4-way configurations available. 50 Ohm splitters are best used with 50 Ohm systems, while 75 Ohm splitters are best used with 75 Ohm systems.
