Use the AP8275 preamp.
For one Tv connected use no splitter , For 2 Tv's connected use a 2 way splitter , For 3 Tv's connected use a 3 way splitter , For 4 Tv's connected use a 4 way splitter. Every time a split takes place the signal gets weaker.
The CM3214 splitter Does Not pass power thru the splitter. So ALL parts of the amplifier must be on the input side of the splitter between the antenna and the splitter.
The Tv/s Must scan for the Digital Broadcast Tv Channels sometimes named the 'Antenna Channels' or 'Air Channels' in the Tv setup menu because the Tv transmissions travel through the air from the transmitting antenna to the receiving antenna.
Do Not scan for cable Tv channels.
