The one on the chimney is vertically polarized and a low gain job, also it's pointing in a different direction to the other four, hard to say without knowing the transmitter arrangements in the area. Low power vertical polarization was mainly used for relay transmitters in poor reception areas, the four horizontally polarized ones look more like high gain jobs. Maybe they switched from relay transmitter to main transmitter after the digital switchover.
