| Taking pictures of this site is difficult due to being surrounded on all sides by housing. Replacement UHF main antenna for DSO has been installed since the previous Sheffield pictures were taken. We have been informed that this antenna is now a stacked Band IV/V cardioid arrangement to allow for the relatively wide range of allocations used. The Band V antenna forms the lower half of the stack, Band IV being the upper half. This arrangement has also been put in place at Reigate, Lark Stoke and Bromsgrove. |
| Three sets of UHF antenna at the top of the tower. The cylinder at the top contains 2 x 8 lambda cardioid antenna pointing towards 105° ETN. (52.4m). Two antenna to cover two separate frequency ranges and are mounted one on top of the other inside the cylinder. These cylinder based antenna replaced an unshrouded 8 lambda cardioid antenna. A small cardioid antenna located on the side of the tower pointing towards 25° ETN (Grey tube antenna in front wire mesh panels) (45.4m) 2 x UHF panels (White cover) pointing towards 65° ETN (42.5m) |
