BA have been trailing a Microwave landing system on some of their 757 fleet. The black 'ring' on the Radome was found to absorb microwaves better than the standard painted radome.
Of course, I'll stand corrected

Actually the black ring is a conductive strip for static dissipation. It's on all radomes but BA doesn't paint it over. Its effect is more for radio communication and to some extent lightning dissipation.
Some radomes have it embedded in the structure so it isn't visible.
It was there long before we considered microwave navigation.

The BA 757 that had the trial MLS system had a black and white quadrant painted on the nosecone. The MLS system was for recording only, there was no indications or controls in the flight deck.
