Vibration mounts for 48" radar array

[crck0848]

I'm looking for a way to quiet the sound from my DRS25ANXT radar. It's mounted on the hardtop above the helm, and it makes a noticeable sound when running. I think it could be solved by adding vibration isolation mounts between the radar and hardtop. Has anybody done this?

I'm pretty sure the noise is just normal gear noise. It is not new; it has been the same since I installed the radar last year. The only reason it's a problem is that the bridge is so quiet (60-65 dB at 8 knots). When the radar is running at the low rotation speed, I don't hear it. At the high rotation speed, [EDIT] I hear it enough that it's mildly annoying.

You might be able to hear the sound in this video clip.

You are correct, that is the normal tone for our radars. Using a sheet of neoprene or cork between the radar and mounting surface will do wonders to dampen the sound when it reverberates in/on tops like yours.

Thank you @FishTech -- that makes total sense. Neoprene will add a little bit of compliance plus some damping, but the unit will still be firm and stable in rough weather. Excellent solution.
