some aircraft with high amounts of carbon fibre or other composites have a strip embedded in the gelcoat, which is in turn earthed to the nearest metallic part of the airframe, and usually ends in a static wick.
and yes, the strips on the radome are 'diverter' strips, diverting electrical energy to the metgallic airframe. any lightening strike into the radar head could end up with the radar screen blowing in the cockpit (along with everything else!) - not a good look.
