Put a satellite dish up today at a mates house (never put one up before) using an app on a smart phone as we didn't have any sort of meter.
After a bit of jigging about we managed to get most channels with a good SNR/AGC readings. One or two channels not so good. RTE1 & 2 showing 0% SNR/AGC so a blank screen and ITV 4 hd very low SNR/AGC which returns a blocky picture. As we have most channels I don't want to mess them up by altering the wrong thing.
So, before I buy a meter, any advise on what to alter first - up/down - left/right or the skew on the LNB ?
