One way female Co Ax (TV/FM/DAB) socket surface plate in white.
Non-isolated so as to pass 12V to a Mast Head amp (if required).
As can be seen from the picture (above right) it is screened. The screening can may require the use of a deeper pattress box or spacer plate (sold here).
See article on surface plates and wiring up this plate.
Occasionally (very occasionally) an alternative plate of equivalent quality (also in white) may be substituted.
