Just bought those and got them delivered today. Still waiting for Mavic. I used something similar on P3S and had good results.

No. You should only buy products that are designed for the Mavic remote controller.is the antenna spacing on the Mavic Controller the same as on the Phantom 3 Pro & 4 controllers

I don't know, guys. Look, I don't claim to be an expert in RF antennas but I do have degrees in physics (Ph.D. Cornell, B.A. Berkeley) and have heard a lot of snake oil salesmen over the years who have claimed great (but completely nonsensical and unphysical) performance of "scientifically engineered" gizmos of everything from audio cables to gasoline additives. Here's what bothers me about the Range Extender shown in the link: if I were a huckster and wanted to come up with some fake "range extenders" to separate people from their money, the thing shown in the link is probably pretty close to what I would come up with. Two shiny, mirrored reflectors shaped in a concave shape as IF the task of reflecting RF waves emanating from the antennas were exactly analogous to reflecting light waves emanating from the antennas. Of course, RF waves have much, much longer wavelengths than light waves and engineering RF wave reflectors is much, much different from engineering light reflectors. Take a look at a Yagi antenna and try to use your intuition and familiarity with light wave reflectors to try to figure out how the Yagi antenna works. You almost certainly can't. Your intuition fails.
Again, I'm not an expert on RF antennas, but my gut feeling from looking at the picture of the Range Extender is that it probably doesn't work and was something that was haphazardly designed by someone who knows nothing about RF engineering.
Thankyou.No. You should only buy products that are designed for the Mavic remote controller.

You are probably correct. But I've already bought a set. LOL Darn Snake oil...
If you want to see results of tests, although not all the variations you have thought of, you can do little worse that looking at those done by the chap who (indirectly) is being accused of selling expensive snake oil.
Drone Valley (I think his name is Rick, but I can't really handle the accent very well).
His tests are on the Phantom, not the Mavic, but the frequency will be the same.
If you want 'independent' tests, with apparently nothing to sell, try this Australian actual flight test. Again a Phantom.
Another Phantom based flying test, defying the 'science'. Although he doesn't show the screen, merely quotes the numbers. What is interesting is that for his final test he flew in a 'poor' signal / range area, and got a much increased range. This tends, in my view, to reinforce what the Drone Valley man asserts, the range extenders don't JUST give you a longer range, but by punching a stronger signal ensure the drone works better in a hostile environment.
What we need now is some Mavic owners to do similar tests.
OF COURSE I'd try this on my Mavic, if only DJI would ship me the one I've paid for
Regards.
