The station was built in 1979 using vertical polarisation only. A horizontally polarised component was added in 1994
to extend coverage to areas of new housing. Transmitter power is split equally between the two antenna systems.
The nominal ERPs for the analogue service were 32W (VP) and 8W (HP), for DSO the ERPs are the same, 7 dB higher
than the standard conversion.
Hemdean relays UHF television from Hannington and BBC national radio to the Reading area. Mike Smith's photos (below) were taken prior to the installation of the DAB aerials.
According to the published data the the tv relay transmits 32W ERP vertically and 8W horizontally, so there are two sets of tx aerials for the tv service. The above photo shows the vertical tv logs as well as the dipole aerials used to transmit the radio services. There are also three sets of Band II VHF aerials here. Is the vertical yagi used for the BBC services and the newer-looking dipoles used for Classic FM? |
