COATING A DOME

[SMITYR1]

SIRS
The plastic dome on my closed array unit is in need of rehab due to UV aging. Would it affect it's performance if I were to apply a 2-3 mil coat of a white polyurethane [ no metallic pigments ] to the unit??

As long as the paint has no metals, it should work just fine.

SMITYR1,

Yes as Johnny Electron mentioned, it is okay to paint your radar antenna. However, the paint you use MUST be epoxy-based with NO metallic ingredients. Paint with metallic ingredients will cause poor performance and possibly damage to your radar.

Almost all white-color paints include titanium dioxide.

Imron makes paint that can be used.

We supplied a client with a new NXT. He asked about painting the dome, we told him not to paint it. He did it anyway and the radar suffered very poor target resolution, among other problems. To his credit he fessed up and admitted he didn't follow our advice. His paint had titanium in it. He bought a new dome cover, all is well.
