Question 1

Yagi Uda antennae are directional and inline with the long axis. Every pic shows the antennae vertical. Shouldn't that be detrimental?

Accepted Answer

I rarely rant in my reviews, but I’m an engineer and so this is an exception. This is not a Yagi antenna. It’s a toy that doesn’t work but kind of looks Yagi-ish. A real Yagi requires a precisely sized and located radiator element, to couple with reflector elements, all of which also need to be of an exact size and location. The existing antennas inside your controller are not designed to be part of a Yagi antenna. The obviously non-yagi sized exterior reflectors do mostly nothing, though if they got the size exactly wrong they would reduce your range.

With line of sight and low humidity and with the stock controller, I’ve seen guys easily get 5 km or more from a Mavic Pro or Mini 2. i’ve never tried it with my Mini 2 because it’s illegal in the USA. Even if you don’t care about that, if you’re getting less range it’s because it’s too humid or you don’t have line of sight. The microwave signal from your controller is blocked by anything solid or with water in it. That includes foliage, water vapor in the atmosphere, concrete, steel, even glass.

If you have line of sight and low humidity you’ll run out of battery before you run out of range. If you don’t have line of sight and low humidity even a real Yagi would do you very little good. And this is most certainly not a real Yagi.

OK, putting away the soapbox now.

Question 2

How does this work when none of the elements actually contact the controller's antenna, and the metal elements don't contact each other?

Accepted Answer

This doesn’t work. It actually worsened my sigmas as it blocks the real antennas. Save yourself some money and a bad experience.

Question 3

Will this work with a hood shade for phone?

Accepted Answer

Sure....well it works fine on mine.
Just look at how the shade fits and see if it would interfere with the antenna.

Question 4

Does this work for exo drones- x7 ranger plus?

Accepted Answer
