annena lost channels only on one Tv

[cassier1021]

Why would my annena work better one one TV and not the other, I had a lot if channels and they slowly lost signel when I put the annena on the other TV they are all back and it is not a matter of location because when I switch the annena they where right next to each other when I treid this.

It is possible that the tuner in one of the TVs is more sensitive than the other. With digital TV if the signal drops below a certain level the channel is gone where as with analog TV is got noisy but still came in.
If the wiring is different then this can make a difference. If you split the antenna to feed both TVs this would reduce the signal too.
