Shielded modular coax sockets - suppliers/recommendations

[converse]

Hi, can anyone recommend a supplier of good quality single shielded coax sockets which fit into standard Euro module plates?

(I'm trying to match all our outlets with our MK Logic sockets, I've got Euro faceplates by Ultima which are perfect).

Also - does anyone know if the angled MK standard sockets (non modular) are shielded?

Different sites report it differently (Q+A on Screwfix suggest not, but the back appears to be shielded).

Thanks!

In case anyone else is looking for similar, I found quality shielded module inserts from Nexxia.co.uk solid metal, with screw connection for centre pin - they fit well in our single and double Euro module plates.

I also purchased to test a MK angled socket as above, it's poor quality non-shielded at the back made of plastic with a PCB connecting through, centre connection held only by friction - on testing today (using the signal strength and quality meter) the signal was reduced by approx 5% to 10% using this over the shielded module.
