SUTTON COLDFIELD

| The 700 MHz band changes were implement at Sutton Coldfield on the 7th March 2018. The changes here only affected multiplexes Com 7, Com 8 and local TV. For local TV additional transmit aerials have been added and this multiplex is now transmitted on two UHF channels. Ch 48 on the original set of 6 tiers of crossed log periodics, which transmit to the south and west, and ch 36 on a new set of shrouded log periodics which point to the northwest. |
| These pictures are all taken from Lichfield Road, which is to the west of the mast. |
| All of the transmit aerial systems in one picture. The local TV aerials are at the bottom. |
| Close up of the local TV aerials with the new northwest facing 6 tier set on the left. |
| UHF main (264m) and reserve (237m) transmit aerials. |
| The interleaved band II national FM radio and band III national DAB radio. Mean height 200m. |
| At the top of this picture is the shared BBC WM and the three Independent Regional Radio services, transmit aerials. Mean height 159m. Four tiers of circularly polarised panels. From this viewpoint we can see that only the bottom tier has panels on all four sides. The panels on the right are facing roughly west-southwest, and the single panel on the left is facing roughly north-northwest. In the middle at 155m, is the disused band III DAB panels which used to transmit the West Midlands regional multiplex. At the bottom is the Birmingham ILR (Free Radio) band II panels. Ofcom data suggests that this is directional to the south-southwest, therefore I assume the purpose of the panels on the left, which are facing almost due north, may be to create a null in that direction. |
| Rotatable SHF antennas, probably for outside broadcast receive. |
| Various receive aerials. On the left, the twin UHF Yagis are pointing towards Winter Hill and the band II Yagi, with only half a reflector, is pointing towards Alsagers Bank. On the right, the twin UHF Yagis, both missing several elements, I estimate are probably pointing towards Mendip, and the twin band II Yagis are the BBC RBS aerials pointing towards Oxford. |
