How many Tv's are/will be connected??
The Tv/s Must scan for the Digital 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.
Looks like all of the network channels , PBS , NBC , ABC , CBS , FOX , MyNetwork , The CW , Retro Tv Network , and more will be received.
DO NOT scan for cable tv channels.
