Doesnt the plastic pipe flex rather badly in the wind at that height?

It can whip a bit in a high wind ...but part of the design is that the centre mast _must_ not be metal ...as this would stop the effectiveness of the ballun ...(matching transformer) wound on the mast ...
..and the antenna would simply not work.

Been up for a while now ..and survived various storms and winds..
If you read the whole article from the above link ...all is explained much better than I could.

No satellite stuff for the moment (aside from a 43cm minidish that was on the house already), Samsung SyncMaster T27B550 Smart TV & Monitor, and a few computers...

Near Pontop Pike, Co. Durham
Looks like a neat job there, got plenty of plastic pipe myself to make a QFH, just need the round tuit to get it made... :D
