    Lmao this shit takes months of construction to custom build and tweak to get right and they’re just gonna toss the entire room out like you can just order one on the internet later

        Anechoic chambers are all like this, they’re utterly soundproof rooms. They’re also supposedly only something humans can stay inside for short time periods because it gets uncomfortable when you start to realise you can hear the blood travelling through your own veins because of how silent it is.

        This one is set up for whatever the job of this antenna is. I don’t know enough about the antenna to comment on it.

            Can confirm. I’ve been in a room exactly like that, where they had an antenna mounted on one wall like the above picture, an RF reflector mounted on the opposite wall, and RF dampening cones on every surface, so that they could measure the frequency curve at a distance twice that of the size of the room (the curve changes with distance)

            Yes exactly. This is a room to test for signals, wanted or unwanted coming out of the devices to be tested. I know nothing about it so don’t spy on me please lol.

          It’s true! I’ve been in one and it was uncanny as hell. I’ve also been in an echoic chamber where the tiniest little footstep or w/e echoes and echoes and echoes

          Wouldn’t be me, I’m built different, I got tinnitus

      • Looks similar to foam sound padding. Reducing waves (whether that be sound or something else) Presumably for creating a room without interference for the antenna.

        It simulates the conditions the antenna will find in space, where everything else is at a “large” distance from the antenna.

        It’s gonna be expensive to build cause you need to build it to pretty high standards. Even small defects can cause interference in your data.
