Here are my snaps of the Cirencester Town mast, which transmits BBC national network radio.

The church tower was open two Saturdays ago, so I went up there and literally was leaning on the mast, which is contained within the flagpole.

The receive aerial is below the tower on the roof of one of the church aisles - a multi-element yagi pointing at Oxford (there's a picture of that too, taken looking down from the tower.) Seemed like quite critical positioning for the RX.
