Hoping someone might be able to help me out or point me in the right direction with this problem. I'm based in Hillcrest on the North Shore. We have 4 TV's in the house. An amplifier (powered) leading into a the first splitter (also an amplifier). One split goes to the master TV and the the second split then splits again into the other 3 TVs.
A few months back we had our UHF antenna's direction (and orientation) changed to point to the sky tower (previously it was facing West) as we started having signal issues. The antenna height was also increased with an extension. The signal we received with this setup was excellent allowing clear reception on all channels on all TVs bar one.
Everything worked well with the exception of our main Samsung TV in the living room. For some reason it would not go well with the new signal giving me 'Bit error level 10' constantly on all channels. Reluctantly I got on the roof and changed the direction (and orientation) back to facing West hoping that the height extension alone would be sufficient to boost the signal and allow all our TVs to work. I was right - for the most part.
The problem is, I seem to lose signal entirely (on all TVs) on the frequency that hosts 1,2 etc. I can marginally pick up the frequency that hosts 3,4 etc but its unwatchable. Settings show 'Bit error level 10' maxed out in red constantly. Here's the catch, it only happens randomly - and for the most part during evenings from what I can understand.
To add to the situation, when this occurs what I notice is that the RF signal that broadcasts one of our decoders to the other TVs via analogue also gets interference. This interference goes away when I remove the powered amplifier (i.e unplug it), but then I lose Freeview altogether.
The issue is biting my head in and I'm hoping someone here might know why this is happening. Is my amplifier adapter at the end of it's life?
Apologies for the long post.
