I had a problem with all the channels, it didn't show almost any. I installed it without having an amplifier on the antenna and it catches everything. Sometimes ERT 1 2 3 do something strange, but everything else is fine.

Excellent.
I had 2 televisions with a splitter, and due to poor antenna installation (which is also in a hard-to-reach spot), I constantly had signal interruptions.
I installed it, and in my tests, both televisions show signal strength and quality at 100%.
It's worth it

In an area with very weak TV and radio signals, even though I have a signal booster, it needs extra amplification to get rid of the interference on the TV and be able to tune in to multiple radio stations. It is also very good that it does not amplify mobile phone frequencies.
