To prevent this, I have decided for the overvoltage protection offered here.
The signal is in my opinion, affect in any way. Possibly an angle adapter is required for the overvoltage protection is not so far dominated by cable in the room.
Conclusion:
With a small investment I can any lightning strikes or different type surge swelled look forward to, and my electronics (hopefully) protected.
The adapter does not even came into use, so I can have the functionality not testify so much. But one feels markedly reduced with the knowledge of this additional protection.
