Loose aerial knocking in to brickwork

[Paul17088071]

Hi all

I am looking for some advice on how to secure a TV aerial please. I have noticed some knocking and I am pretty sure the culprit is my tv aerial knocking into brickwork, it’s only when it’s windy that it occurs.

I think the banging is coming from the section circled red. How is it best to secure this to prevent it knocking the brickwork?

Many thanks, Paul.

Isn’t it hanging upside down?

Reverse the L shaped mounting pole so it holds it further from wall .
Or fix it right way up so it’s clear of roof.
