From what you've photo'd it looks like a Phase 8 monopole, which are commonly used to host 5G. However without seeing the top, particularly the top most antennas, it's impossible to tell if there are any 5G antennas installed on it.
I apologise I thought I had got all the mast in the photo I will get another one as I go past today sorry…….
Also how long does it take for a mast to be made live after it has been built as I know from the planning application it’s a three mast just wondering as I’m looking at getting 5g home broadband as it’s way faster than my Hbb that is 25-30 mbps….. I would like to test the speeds with my iPhone though before committing to a 12 month contract as the speeds at the next closest 5g mast are 800mbps at roughly the same distance away from the new mast
