Beautiful work. Why haven´t you tried using clover leaf antennas?

Could anyone help me with a delicate problem: If we use a helical antenna with 60* angle i should mount it 90* because after 1km the base of the cone should be apprx 1.1km right? Only problem as I see it is that we get theoretically radio shadow within a radius of apprx 400m. I found this...

Patience my friend,

Ok, so after a bit more prototyping and programming. My main concern have been getting the right precision of the antenna movement to the right weight, speed and dimension. I have experimented with: Stepmotors (Great precision, easy to code, really heavy, large, slow af, weak af) Continuous...

Yes, the best way to do it is having antenna trackers on both the ground station and on the drone.

I have thought about this as well. However from my understanding of DJI its not open source in any way. Furthermore the GPS + compass module is quite cheap and easy to implement (for my programmer). Or so he says anyways. And if I use a dedicated GPS + compass for this device its entirely...

Yes, but thats for the ground station. My device will mount under the drone and direct the drones antennas. This enable the use of directional antennas on the drone. My oh my

Oh cool. I have managed to get help from a professional programmer via Freelancer. I was planning on using the Arduino Pro Micro with a external GPS + Compass module that will mount on top of the drone. My main consideration right now is choice of motor. I have gone from micro-servo to stepper...

Oh I do; L75 x W55 x H35mm (without antenna mounted) and about 100-200g depending on final decision on motor. Currently I'm working on the code and waiting for parts from Asia.

So this is the first design. Please come with suggestions for improvements. I am looking for an Arduino programmer to embark with me on this mission, please holla at me.

Great progress beanbubba, cutting edge stuff right there. I'm currently researching the possibility to design a minature antenna tracker with helical directional antennas to mount under the Mavic Pro. The tracking helical antennas with a 2W phantom amp would boost the range significantly. I...
