Restoring a Broken Antenna Socket Connection

Huge impedance bump and matching reflections. Big leak as well. Just replace the connector.

This is an insult to any RF guy

Beyond horrible. Bo shielding, if'll leak the signal, big time.

Tell me you don't understand s-parameters without telling me

That unshielded piece of cable (red/grey wires) is a disaster for RF performance. 🤦🏻‍♂️ Not only will it cause massive signal loss (easily 10–18+ dB), but it will also skyrocket noise levels. As a result, your Wi-Fi will degrade to something closer to Bluetooth v1 in both range and speed. 🔻 On top of that, it will generate strong QRM to nearby devices and completely mess up DFS (radar detection), causing constant channel switching and instability. ⚠️ Proper shielded coaxial antenna cable is mandatory here. ♻️

Impedance matching has left the chat

I really want to see what a TDR and VNA would have to say about this ridiculous absurdity.

This might have been restored, but not repaired

Someone who doesn't know how RF works did this.

Chapuzas

Cool demonstration of a mismatch.

The operator is not a professional and lacks basic knowledge regarding the repair of RF circuits.

Delete this or RF guys are gonna Directed-Energy attack your a**

It's trivial to replace that U.Fl connector. 🤦🏻‍♂️

You got my antennation.

Literally the worst way I have seen to fix this problem lol. You could easily reuse all parts

🤣🤣🤣🤣🤣buy the antenna bro $5

Save the work, use a USB plug!

Or...

every time I assume account region, I guess it right for some reason

That just added a new non matched antenna section.

Wtf

Rage bait

ジャンパー線、３０年以上前はプロの仕事としてやってましたな～ パソコンのマザーボードでもリサイクル部品は ジャンパー線で修復してました・・・

I mean, it technically reconnected it but ew

fuk noooo :-(

... or just re-crimp it... 🤷‍♂️

Why 😯

In a pinch that is good. But if you had the skills to replace that socket and attach the wire that would have been amazing. However in Red Neck phone repair..
