Just wanted to say that I found a really nice enclosure for my ADS-B setup, and I think it will work for others as well Its an Orbit sprinkler system enclosure.
Its really nice and has a mounting platform that is removable. There are two holes in the bottom of the case, a larger one that I’m installing a Molex waterproof ethernet connector:
The other, smaller hole I’ll install a chassis mount N-Connector.
I’ll take pictures when I get everything installed…
