234 30 37928
(octopus16) I thought site would be located at two masts near War Memorial, then removed site from location as site visit confirmed disused 2G panels are located on these masts. I am continuing field testing to determine location. 5G is also broadcasting on n78 from the unlocated site, along with several other 4G bands.
EDIT: Hi Dave - the site at the memorial was still active for Orange 2G as recently as this year, but noticed it was off a few months ago (was probably one of the last still running the 234-33 code in the UK). It could be they've made it 4G with the same panels, but that wouldn't explain n78 (unless using more distant n78 and Cellmapper incorrectly reporting it).
(octopus16) Hi. Due to the topography of the area and lack of line of sight into Cowbridge town centre from the only other possible sites; St. Mary Hill, which is shielded by the topography of the area and St. Hilary, which I have confirmed is not broadcasting n78; I am fairly certain that the new 4G carriers are broadcasting from the same, unlocated, site as the 5G is, where the n78 RSRP is -82dBm in Cowbridge town centre. However, I am not certain and will run more field tests tomorrow. Thanks.
