How to protect the satellite receiver from lightning

There are lightning protection devices (lightning protector, lightning arrester) specially designed for coax RG6 or RG59 cables and that mount inline with the cable.
Simply fit a lightning arrester within the cable itself or at the entrance of the receiver.
The receiver lightning protector has no impact on the signal strength or image quality.
It has a built-in F-plug on one side and a female F-connector on the other side in a manner to be installed without the need for any tool.
The ones that are more efficient do have a ground wire connector.
That's it!.
