Replacement wifi antenna

Thanks for the advise. I’m gonna check that out. The antenna cable is pretty long, so there is a chance it’s touching the chassis more than once along the coiling (it’s coiled like 3 times inside the chassis)
Sadly, I don’t have another device to test it on, but I guess that, worst case scenario, I can settle for the signal I get.

I mean, realistically, I’m not going to have the device with me everytime I’m cooking, I won’t need superb internet either all the time (good enough internet will suffice)

But it felt good to have superb internet for a while haha. If I find something else, I’ll let you all know.

Ok, I managed to get a decent enough signal (35% to 45% strength)at the spot where it dropped to zero.

I read that the antenna should rise above the chassis, “at least 1cm” so it occurred to me that my tests with the laptop antenna were probably when it was hanging.

I decided to add a really thick buffer and that seem to have solved the problem. Moral of the story: get an external antenna.

My solution is ugly but functional.

I am just throwing this out there… Antennas | SpeedyFPV These things are made for strong signal… no one wants to crash their drone due to loss of signal

There’s only two antennas on that page that will work.

There are a few antenna’s and a few u.fl to RPSMA connectors for relocation if needed.

Yeah, really best to stick to wifi/BT specific products, no shortage of those and the required rp-sma to u.fl cables or patch antennae with u.fl attached if that’s what you want.

the piece of plastic I used is much thinner than this, I basically cut piece from the packaging of the SD card and used superglue.


Some also suggested to make the cable loop behind the SODIMM slot like so;

overall I am getting around 40% in places where I used to have barely stable 30% signal strength. that 10% improvement does seem to make difference for my case.

Me too.
Just two layers of package plastic and double sided glue tape.
The signal is *fair.

*basic is to switch antenna from internal to external:
sudo nano /boot/firmware/config.txt
dtparam=ant2

and only two of the antennas support wifi.

Come to think, maybe the stock antenna would work fine if you just use a buffer thick enough to rise it above the chassis.

I’m paraphrasing here but the guys on the thread I found, said the chassis worked as a capacitor or a faraday cage, absorbing the signal. That’s why you have to raise it.

My understanding is that it’s like being underwater and trying to breath through a straw.

  • If the straw is underwater, no air will reach you.
  • If the straw is at level, you will breath but any disturbance will let water through the straw
  • If the straw is high enough above water level, you will breath without issues.

As part of my tests, when my laptop antenna was placed as instructed by the manual, I connected the uConsole to my phone’s hotspot and pointed the antenna towards it. Signal was 80%
When I pointed somewhere else, just by doing that, signal dropped to lower 60’s. It only reached 90+ if I placed my phone right in front t of the antenna at 0mm distance.

So, my guess is that, by rising it, you give your device a better chance at picking up the signal.
This is pure speculation based on mere observation. I have no instruments to measure things… But I can say with confidence (based on experience) that if the antenna is raised enough, your signal will be a LOT better
