These satellite finders are really useful little helpers when it comes down to perfectly aligning a satellite dish.
In this YouTube video we can see how sensitive the meter is. This sensitivity allows finding the sweet spot of the satellite dish. Here, we’ve got already a perfectly aligned dish, the meter is at the maximum. Even the slightest movement of the dish to either side of the perfect alignment reduces the signal level (and audio tone) of the meter. You can see that once the fine-tuning is finished, the signal level is again at the maximum.
Some people are trying to align their satellite dishes with the on-screen digibox signal bar which is way too slow, inaccurate and not sensitive enough for a good alignment. Save yourself the hassle and get one of these satellite finders – the prices dropped down to almost 5 quid (they were 40 quid 5 years ago).
