[CA] [CA11] Radar display issue, connection issue

[Seagirt]

See picture below. The striations displayed in the radar image in the MFD come and go, sometimes worse sometimes better. When the range is changed the striations appear and then gradually fill in with time. A couple of times I've tapped the radar dome and it seems to make the striations in the display better. I've double checked the cable connections at both ends to make sure they are secure.

Sorry, I don't have the specs on the equipment. It was installed 2015; basic 7' MFD and digital radar dome package.

Any ideas on what the issue is and how to fix?

Welcome to the Raymarine Forum Seagirt,

The symptoms displayed are indicative of a failure within the radome's circuitry necessitating that the radome be sent to Raymarine’s Product Repair Center to be bench checked / serviced.
