I thought site would be located at two masts near War Memorial, then removed site from location as site visit confirmed that no panels other than Airwave and 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.
Someone else has also, understandably, placed it at this location. I have restored calculated location, as this is not the correct location.
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).
