Missing Freeview Channels

[DOUBLEPLUG]

Folks, looking for some assistance. Recently had to swap out old TV amplifier - 8 port for new Labgear model. Now I am missing all the stations on muxed channels 28 (BBC etc) and 29(yesterday etc). Same on all televisions (mix of smart and external review box) and also when I connect single TV to aerial without using amp. Signal is strong on other channels received. wiped and retuned all the TV's Also tried fitting in attenuator before the amplifier just in case signal was too strong. Good cable used throughout. Think I have tried everything. help

you have retuned ?

It may be that the output channel on the new Labgear amp is close to a local transmitter or one of the rf outputs is close to the rf output of the new amp. It may be worth changing the amp output channel and concentration initially on one TV. If you get that to show your missing channels yo may have to retune all the other appliances to that output band. You may well have the new amp on the same channel as the old one, but different horses for different courses. The properties of the new amp may just be causing what may have been borderline into a bandwidth clash. Good Luck.

It seems obvious to me that the gain on your new amplifier isn't as good as the old one was providing.
