You mentioned earlier that when it disconnected during one shower, it recovered after about 18 minutes.
That suggests (but does not prove
) that the problem is likely to be somewhere in the exposed length, from and including the 30 yard pole to your house. particularly at attachment/restraining/suspension points.
My reasoning is that as the recovery time of 18 minutes is relatively short, it is likely to be moving/running/draining rain water, rather than a relatively static, accumulating "pool", that would take longer to dry out.
Also, has it happened during high winds without rain, which would suggest suspension points? In this case, more likely to be brief and intermittent.
Again - not absolute proof.
Heavy mists, frosts etc?
Check those areas/points, both dry and when raining, looking for runnels of draining water.
You may find binoculars handy!
Any other lines on the pole, so neighbours with similar problems?
Don't overlook the possibility of disturbances between the pole and the cabinet - eg new fence posts erected, old fence posts taken out, ditches etc.
Also don't forget the QLT.
