I really like the clean lines of it - no aerials or other bits sticking out of it - some others brands looks like they came from a Star Wars movie !
I made a bracket for it to mount on so it’s not intrusive.
I’m no geek but sure you connect it to a POE ( Power over Ethernet) cable - NETGEAR sell these which you hook up directly to your router. This is how it’s powered up.
Our garden is 160 long and it beams the WI-FI signal out perfectly. I would think the signal extends well beyond this.
As a test, I streamed a movie from Apple TV. It streamed perfectly just like inside the house.
Would highly recommend this .
