Good points. Hopefully, he scheduled a truck roll. They should fix any bad ends on that too... And then, I would go back and seal them.One thing to note. Usually rain, in itself does NOT cause signal loss. It is almost always the thickness of the clouds to the south that makes the difference.
Here is alabama we get rained on often, but very rarely get loss of signal, and my strengths are low (on purpose). we don't lose the signal because the rain is VERY localized. I've seen it where it was pouring on my backyard but not on my across the street neighbor.
In the past, if rain caused my signal to go out, I always found that there was a poor connection that was letting water in. I would go through the cables and find a connector at the grounding block, or some where, that wasn't tight.
I would use some stuff called Sat Seal on all the connections and that would take care of the rain issue. (one time i did it during the storm, NOT recommended!!!)
Please remember "Lose" implies 'Loss', "Loose" does not.
