Not especially high gain however I do notice a VHF halo on the house on the right in the first pictureThat looks like a high gain antenna. The bird is simply admiring it.
Perhaps the Red Kite was checking that out.

Do they only appear in England or are they all about the UK?
At one time confined to Wales, a reintroduction scheme has brought them back to many parts of England and Scotland. Central Wales, central England - especially the Chilterns, central Scotland - at Argaty, and along the Galloway Kite Trail are the best areas to find them.
