Well yeah, it's the newest fad: wireless outlets.
The same PSAP that has this silly antenna setup also involved an electrical contractor that tried the "wireless outlet" trick on us. When we moved in, we found several outlets that didn't work. Since I'm not officially an electrician, I kicked it over to the right people.
They checked with their meter, no juice.
Take the outlet cover off.
Remove the outlet.
Yep, no wires going back to the panel.
Found a bunch like that.
Electrical contractor didn't do their job.
Inspector didn't do their job.
Whole place was little Charlie Foxtrots like that.
