[QUOTE="CyberSimian, post: 1259419, member: 141969"] From your screen shot, your signal level looks very low :(. Here is what I get for a DVB-T channel using one of my Pinnacle tuners (which are less sensitive than the TBS tuners): [ATTACH]201636[/ATTACH] Although the signal level is only 50, the quality is 100 and there are no discontinuities detected. Nevertheless, over the past several days I have noticed very occasional and momentary pixelation on a small part of the screen (I think that the weather conditions can affect this somewhat). A signal amplifier [i]may[/i] improve your reception, but I suspect that a better aerial would provide more benefit. My Sony TV has an "tuning details" page which shows (among other things) the "C/N ratio" (carrier/noise ratio). This is the digital equivalent of the old analogue "S/N ratio" (signal/noise ratio). I use two aerial amplifiers in my setup, and I was curious to see what effect they had. So I connected the aerial directly to the TV, first with no aerial amplifier, then with one, and then with two. The result was that the C/N ratio was best with no aerial amplifier connected, and worst with both aerial amplifiers connected. :( Aerial amplifiers are of most use when you need to split the signal among multiple aerial sockets (I have five sockets in my setup -- two on the TBS tuner card, one each on the two Pinnacle tuner cards, and one on the TV). But you need to have a signal of acceptable quality to start with, otherwise you end up with a higher-level signal which has worse quality (since the aerial amplifier will itself degrade the C/N ratio).
