Anyone have a similar experience? I haven't gone back up on the roof yet to check the antenna for damage or the coax for water.

It went up this time last year on a 10' mast on a chimney mount, with 40' of LMR400. I have a drop amp on this feeding a 3-way splitter for 2 TVs and my Airspy R2 spyserver. I notice the issue on the TV the most as local stations that should have an overwhelming signal start to go pixellated or drop out altogether.

I am wondering if the moisture is shorting the antenna or if it is leaking through and getting in the coax. It clears up within hours or a day of the precip stopping, so I feel it is an external problem more than an internal leak. Perhaps a liberal coating of an oily protectant externally?
