Directional Patch 5.8Ghz SMA Articulated Antenna for RF Explorer

I bought this antenna because my neighbor was spraying radiation across the street disrupting and damaging security cameras...even wired ,non-wifi ones. I was hoping this unit would show pulses coming from his house and show virtually none when facing the other direction. After doing many tests all directions seemed about equal power and so the results weren't helpful. I'm now curious if wifi signals aren't bounced off of TV screens and other glass in the house for erroneous results?I was able to prove it was him by recording him from a camera he was not aware of and all pulses stopped when he moved his attention to the new camera (human behavior versus signal proof) .

This antenna always had a slight rattle sound vs my 2.4ghz version which didn't. I only used it once and put it away, not sure if it was working. I took it out more recently and cracked it open to find all the internals loose. I was able to stick the metal plates back in place, and it seems to work properly now, but I'm not sure if they will hold. Maybe I just got a dud, but buyer beware.

Very poor performance at 5.8ghz. Expect to lose usable signal in less that 50m when literally pointed directly at the transmitter with clear line of sight. Furthermore the build is incredibly cheap such as loose and floppy joints that won't stay in position.

Like the product so far and works with my device as expected. No one near professional, but gives you the idea on direction which is enough for me.

It expands the attenna range.
