Who should be a satellite system At length know that the longer a cable is, the weaker the signal. That's why it's important to buy a hochwertigs cable in which this effect is minimized. Without further ado, I decided for the 30m cable from Vivanco. I have almost exhausted the 30m and have a very good signal. Is also good that all the necessary things, such as plugs and "rubber protection" for Outside with it are. If the cable buy back in any case.
