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.
Even if this was right, which it isn't, wifi stopped being 2.4Ghz exclusive almost 20 years ago. You have 5Ghz and since 5 year ago or so, 6Ghz, with significantly shorter wavelengths.
And if I look at the frequency spectrum I see that all my neighbours use 2.4GHz (9 are in channel 8) and I got the entire 5GHz spectrum to myself.
Channel 8? I thought modern routers automatically select 1 6 and 11. That must be some ancient equipment around.
Probably because for most people as long as it works it works and there's no reason to upgrade.
Sorry, but 9 networks on channel 8 can hardly be described as something "working". I'd bet you barely get a 1mbps on that, and a crazy jitter and packet loss.
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
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.
I was agreeing with you
Ah lol I gotcha!
Yeah, It looks like a Cisco Aironet 2702i 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.
It'll more likely act as a faraday cage.
I guess lol
