You will find everything with a good guide

Need a gauge? A good gauge? We recommend the SF-100 Sat Finder signal meter
Sometimes it works and after a few minutes you catch a signal, but what if the wind or a big storm comes and you will see the words "check signal level "? You know what that means? That yours the antenna is not tuned properly . And it was precisely to avoid this that was invented digital signal meters . They will save your precious time, they will save your nerves and in return they will guarantee a perfect, undisturbed signal. Such meters are small, compact devices operating on digital technology. We connect the meter with a cable to the antenna converter, and on the other side we connect the cable, the end of which is inserted into the decoder. And now we move the antenna watching the gauge.
