For 1 tv connected use No splitter.
For 2 Tv's connected use a common simple 2 way splitter.
For 3 Tv's connected use a common simple 3 way splitter.
For 4 Tv's connected use a common simple 4 way splitter.
The Tv transmissions are strong. Most likely a antenna amplifier will not be required.
As always trees and tree leaves do a real fine job of reducing or blocking Tv reception and so do buildings and other obstructions including your own house.
It is best to install a antenna at a location that has the least amount to no amount of obstructions of any type or kind in the directions of reception and that includes your own house.
The Tv/s Must Channel Scan for the Broadcast Tv Channels , sometimes named the 'Air Channels' or 'Antenna Channels' in the Tv setup menu because the Tv transmissions travel through the air from the transmitting antenna to the receiving antenna.
DO NOT channel scan for cable tv channels.
