Greetings ..
I have a tower containing 5 routerBOARDS 912 ..
it's connected to sectors but the man who put it there didn't cover the CH0 and CH1 area that's shown in the picture i attached in this post.
is there a real danger to the device ? I mean with the outside environment like the hot sun or the rain ? please inform me.
Regards.

If there are cables connected to CH0 and CH1, why would you need to cover it?
If there ar NO cables connected, I don't think it really matters if they are covered. Just make sure that the radio is disabled and clean the connectors when you are going to use them again.

It is connected to the antenna by SMA cables and it is running and broadcasting ..

the question is .. does mikrotik recommend that it should it be covered ??

Not required, but of course, you can improve the connection if you want, there are many ways to do it.
Cover can be used if you have flexible cables. If you directly mount the antenna on there, there is no choice, that is why there are rubber rings below the connectors.

Thank you for replaying I feel better now really !
