Hmm I don't think I get this one.
Is it because its in a cage? I don't think that will do much to block the WiFi antenna.

The elements of the cage will probably interfere, but won't straight up block the signal. To be an effective faraday cage, holes in the material must be no bigger than 1/10th the wavelength.
2.4GHz wifi has a wavelength of 12cm, and 5GHz is about 5cm...so holes in the cage should be no bigger than 1.2cm for 2.4GHz, or 0.5cm for 5GHz.
I may expect some signal reflection and likely a high noise floor as a result to being so close to a hunk of metal. That'll cause some problems.
Problem #1 is this AP is oriented vertically on a wall. The antennas in these models are designed to be parallel to the floor, and usually not much higher than 15ft.

If it wasn't grounded the cage wouldn't block the signal?

This is a 2.4 GHz directional WiFi antenna. Only the back element is connected to the transceiver. All of the other elements are there to focus the signal. Anything metallic within a few feet of an antenna will have a substantial effect on the signal. Think of it as light, because it is, only transparency of materials is a bit weird. The biggest issues will come from metallic materials that are earth grounded and anything with a wire length that is close to the wavelength of the radio light or below, especially around half and a quarter of the wavelength. That pictured wire pitch is spaced very close to the approximate 2.4 GHz wave length. For example most antenna are an insulated trace on a circuit board that is insulated with ground up to a point and then there is a small circuit element that stops the ground and the actual antenna trace continues for the respective light wavelength to transmit or receive. All an antenna is here is an exposed length of single conductor wire.
That's just an AP. That's not a directional antenna for a wireless bridge. You can even read the AP sticker on it.

All those confident words they typed... for nothing. Lol

The mesh is not dense enough to be a true Faraday cage for 2.4GHz, but is dense enough to hurt signal strength.
Probably not for a MIMO AP. The whole idea is that you solve the equations to optimize in the presence of multipath. It's legit wizard shit but it's the reason why your cell phone works in a parking garage, because the optimal channel is bouncing off the ventilation shaft. For any reasonably modern AP, it should work the same way. This might hurt a bit but not that much.

I'm just impressed they labelled the WAP.

I think they were trying to say that the cage in front with the AP behind, acts as a directional antenna. Similar to how Yagi antennas have metal elements that aren't connected in front of the actual antenna.
But I don't know enough antenna theory to know if that's correct.

Maybe if use smaller, tighter squares.

I must be missing the joke or something? That's literally what this is. It's an AP not a directional antenna. I have used a ton of directional antennas. Hell I have one that I'm using to get my network to my garage which is 1/4 of a mile away.

that's actually massive, I thought it would be like half a centimeter at most

They need more "I" in their IT, plastic protectors exist.

The cage is to protect it from flying balls.

I was agreeing with you

wrote on last edited by [email protected]Newer standards are substantially shorter at 5GHz and 6GHz, but this comes at the cost of significantly worse signal penetration through walls.

The mesh is just about the size of the wifi wage length

Why would it be locked????
