The weather cooperated enough for me to mount the 1090mhz antenna onto the side of the house and run the cable up through the soffit into the garage attic. I previously swapped the light fixture in the garage for a 6-plug outlet to run the work lights, so I was able to connect into that for the power.
I’ll be interested to see how this FlightFeeder Orange Box operates in the garage attic during the summer here in Texas. It’s passively cooled for now, but I might have to setup a temp-controlled fan for the hottest days. We’ll see.

Initial results are definitely better than when I was testing it with the antenna in the upstairs window. I’m picking up aircraft over 150NM away – in Dallas.
