Second AP that was full of water. Been up for 3 years. Popped the ethernet gland and water ran out of it. Anyone else have the seals fail around where the body of the AP mounts against the antenna? [IMG_0530.jpg] [IMG_0531.jpg][IMG_0534.jpg]

Oh, yes, YES. We had 3 or 4 450m with water inside, it happened when raining with strong wind (we think so), Cambium always denied this is a know problem. Glad we are not alone (sorry for you).

Any ideas on how/where the water is getting in or how to prevent it from happening? Any warranty success RMA’ing them?

Well, the first one was kind of like, okay maybe it's just a bad apple lets just send it off for repair. I questioned them about this and they neither confirmed it was an issue nor denied. But, they haven't charged me for that repair yet as it is still at the repair facility in Florida. The sec…

We had this happen with at least one AP right when we were deploying a couple of years ago and they replaced it. They then sent a bunch of new cable grips (I think that is the right term, the metal screw in thing) that had a slightly different design. We have not run into the issue again... or at le…

We have seen this once as well. We just figured it was a freak thing, but now . . .

We have had over 12 units fail with water ingress , this is a know issue and cambium has made changes to the constrution of the Medusa 5ghz AP. We put weep holes in the blank caps to let water out, Long story short after a year of testing the issue we have determind tha extream tempetuer swings allo…

We have lost about 3-4 units now. It is a problem. So far Cambium has been looking after us.

Yes observed similar issue in 450m radio developing cracks in antenna leading water ingress/psu port damage and radio not powering on [Screenshot_2021-08-03-18-56-16-14]

Happening specially with 450M ODUs. Maximum cased are found with cracks on ODU upper part thus resulting in water ingress and eventually making the device faulty. There are other cases too, where even without cracks on the radome, water ingress is there even after weatherproof is so very proper. S…

Ever since I started sealing the 450m with a thick bead of silicone where the radio and the antenna mate (top seam), no issues. I do this now with brand new 450m too. [image]

Anybody else have problems with water ingress on 450M?
