Looking back, now I see the lack of a drip, and the lack of a suitable fitting.
Thinking (& looking) there looks like a cut off cable in the blue area & what may be an insulator on the wall. If that is so...
The 'mast' could have been a replacement for whatever was once at the blue wall area.
Whatever....IAN...what's the deal here??
