My broadcast tv channels change every so often, sometimes adding and at the same time subtracting. Solution?

I have a somewhat new TV that doesn't require a 'black box'. I have had no issues until recently. As l receive only Broadcast channels, by choice, the selection changes. Sometimes I don't get the stations I've programmed in and other times I receive channels l've deleted. Strange!

You'll probably need better antennae (or an amplified one). I doubt TV broadcasters in your region play ON/OFF game that often.

YOu can also check with your neighbours whether they have similar experience.
