Fiber Internet and cable are included in mandatory HOA fees (yay HOAs) so this seems weird. No other homes in the area have anything like this. Also, I’m 99% sure this unit is a full time Airbnb if that might matter (and why I can’t just ask my neighbor wtf is on their roof). Did some reverse image searches and didn’t find a match, that 5G seemed closest to my untrained eye. I don’t like tech shit that I don’t know what the hell it is. Particularly when it’s aimed close to my house. TIA!
That indeed looks like a cell network antenna.
My friend is an RF expert and immediately said that’s a cellular antenna, looks like LTE most probably but might support 5G.
It’s a 4x4 MIMO, most likely LTE+5G; a service like T-Mobile Home Internet uses a hybrid design combining the two (B66 + n41 e.g.)
I’m not an expert, but I’ve worked a lot with LTE antennae, and can confirm that your expert friend is not just pretending.
