That reminds me, the Myantenna line isolator I just installed had a tiny weep hole on one end.  It would have been awfully easy to install upside down.

Balun Designs recommends and sometimes puts weep holes on the bottom of their balun boxes. I had some cable junctions in an 8" 'waterproof' electric PVC box. I traced a failure of the connections in the box- IT WAS FULL OF WATER!!!. Drilled weep holes in the bottom after that.

My strategy is no coax connectors out on a boom.  Feedpoint ferrite chokes are in a PVC junction box with coax in thru a watertight gland and two glands out for short #10 leads to the feedpoint. So no exposed solder or connectors or nuts on plastic to loosen.

Not a bad idea, it's how we construct stack switches here. It's way easier to weatherproof an in-line splice than a panel jack.

I've never figured out how to really make an S0239 watertight.  It rains a bit here in Seattle.

I leave a way for a little moisture to leave the box. My box cover faces down. I leave the cover gasket off, and I don't tighten the cover excessively.
