Are you not worried about lightning
Spot on. By law, you have to install proper lightning protection on any antenna system that is the highest point on your home.
You cannot legally do this yourself either.
It must be done by a certified electrician that has the knowledge and certification.
Your CoC is compromised, your home insurance is compromised as it stands now.
And that flimsy little pole is not providing you with adequate stability either.
All in all, a disaster waiting to happen.
And, surely RAIN has the info available about in line protection on that signal cable?
Please tell me that they also have a fibre connection available iso, cat 5/6?
