This has ‘electrician’ written all over it. The use of earthing tape is conclusive evidence! Most electricians realise that RF is not the same as AC mains and has to be treated differently. Some electricians, however, believe that RF is just the same as mains power except that it can’t electrocute you. This is the work of the latter variant of the species. All this unscreened inner conductor will radiate signal and pick up interference, even inside a steel backbox. The presence of two cables suggests a daisy chain of outlets. At each there will be a severe impedance mismatch, causing signal reflections and losses. It’s a shame really, because the job has been done quite carefully. It’s a pity about the lack of knowledge.
