Rescan scan for Digital Broadcast Tv channels.
Digital Tv tuners can develop - Digital Glitches - that are not cleared out with a simple channel scan.

_________________________________
During the setup and testing phase have only 1 Tv connected , No splitters.
__________________________
As always the starting aim direction is --> the starting aim direction.
The antenna can be turned and moved up and down and the location can be changed for best reception.
Most Digital Tv's have a signal strength meter and some Digital Tv's also have a signal quality meter.
_____________________
As always , trees and tree leaves do a real fine job of reducing or blocking Digital Broadcast Tv reception and so do buildings and other obstructions including your own house.
It is best to install the Tv antenna at a location that has the least amount to no amount of obstructions of any type or kind in the directions of reception including your own house.
The Digital Tv Must Channel Scan for the Digital Broadcast Tv channels , often 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.
