DJI Rc Pro where are the antennas?

[Raffaello_IZ0QWM]

Hi everyone,

after the written communication on the specs of the Mavic 3 which says that the RC-N1 goes to O3 when connected to drones capable of going to O3, I created a video (only in Italian) in which I explain the differences in the radio sector between RC-N1 and RcPro.

During the study I analyzed the FCC reports of the RCPro and found only 2 SDR antennas (ocusync) and 2 WiFi antennas mentioned.

Has anyone removed the RCPro door where it says ANTENNA?

I would like to find the other two antennas dedicated to Ocusync which should be for reception only.

Anyone have an RCPro teardown?

Been waiting for an RC-Pro teardown myself! Want to know exactly where they hid the noisy transducer inside, that makes the annoyingly loud heart attack beeping at 15% battery! It needs a muffler! Show us your RC-Pro tear down photos, please!

RC Pro's drone datalink antennas are those movable "sticks", whose sides you're intended to keep toward drone to have signal.
(vs. fixed antennas in RC-N1's phone holder)
If there's internal fixed antenna that's for Wifi.

This is what we can find in the FCC reports. In the Rc Proc specs we can read: 4 Antennas, 2T4R And in the WiFi section: Support 2×2 MIMO Wi-Fi DJI RC Pro - Specs - DJI DJI RC Pro is a professional-level remote controller that features a powerful next-generation processor, O3+ video transmission technology, and 4G network communication. It also uses the same control sticks as the DJI FPV drone to provide a smoother control experience, bringing aerial... www.dji.com So i guess to find 4 antennas for SDR and 2 for WiFi. It is possible that the two front antennas are not mentioned at all because only the transmitting antennas are important for FCC reports, as it should be. However I would like to know how they are made: what polarization they have and what gain. Another possibility is that WiFi antennas are also used for SDR reception. But I don't know the radio frontend chip inside RcPro

Is there no bottom side view that would show the location of the transducer?
Two of the three images above are identical top down views.

Removal of the RC-Pro door reveals the enclosed compartment in which the 4G Dongle is to be attached, with an antenna connector for it. No sight lines or access to the rest of the interior.

Yes are identical, only the identification of the antennas are different.

Yes are identical, only the identification of the antennas are different.

So the FCC filing shows no bottom up view?

No bottom up view.

No bottom up view.

Thanks.
Hopefully, someone has an RC-Pro teardown video or photos!

Just today published on FCC the internal photos of Rc Pro https://fccid.io/SS3-RM51021/Int ... rnal-Photos-5494022

That's very helpful!
I think I have found the noisy transducer!

Looks to be about here, from the outside, on the back of the RC-Pro.
Drill small pilot hole in the center of the circle, to reveal the top of the silver transducer, and apply pressure through the pilot hole against it with a cut off Q-Tip!l
Make it mew like a kitten, instead of howling like an alley cat!
