"No Data Input" from Radar to Raymarine C80

[Northeaster]

Hi Folks,

I am getting a "no data input" message on the display after reconnnecting my 18" Radome.
I did splice all of the wires in the same manner as last year.
Although likely not the best splices, I used marrets for the power leads, and silicon telecom connectors for all ther leads, including the very small coax, which I just stripped back a bit and inserted the center into the connectors.

I woudl appreciate if someone can tell me the proper connector / procedure for splicing this small coax, but I would think that even with my splice, I owuld get some signal.

Checked the connector at the display, and the one in the radome, and look fine.

The small radar icon on the display does not have an x through it, but the softkeys to power it on / standby are greyed out.

Any thoughts?
