Hi, Can anyone recommend a decent amp / splitter or a good setup guide as the snr is way down and picture pixelated on some hd channels. I have a z h1 which always shows snr as 99 then around 24 on bad channels and a mutant hd500c which shows snr of around 34 on good and below 30 on bad. I have tried scanning without splitter first but its needed for the bb.
