I saw something similar on YouTube, and this is my version. All it takes is a coffee can.
Choose a 12oz can made of paper. Most of your store-brand ground coffee comes in a paper can with a foil layer covering the paper. This is what you want. I used a hacksaw to saw off the metal ring at the top, and then sawed off two sections about 3 inches wide. You'll want to cut two pieces, sawing or cutting a cross-section of the can, about the same width, around 3 inches.
So, now you have two rings. cut through the ring and bend outwards a little. Yrim with scissors to get a clean line, and make one piece about 7 inches long, and the other trim down to 6 inches. Nothing critical here. Round the corners a little to make it look nice. In the middle, you'll want to cut a notch. Take your control box and make the notch in the shorter piece just enough to fit over the 5.8 antenna base. On the other piece, cut a deeper, narrower notch to fit over the Wi-Fi repeater. When you finish It should look like this:
I then use a piece of black electrical tape, with a slit cut in the center, to hold it lightly to the 5.8 antenna. I just want something to hold it steady. Anything non-metallic will work, you don't want to use a piece of the can material because it will de-tune the antenna somewhat. Tape works well, and is sticky enough to hold it to the antenna.
On the Wi-Fi repeater, you can just slide the curved piece behind it and over the mount. Make sure your notch is deep enough that it centers top and bottom. Keep the notch narrow enough to hold it snugly.
What we have now is two reflectors that can be taken off or put on as needed. These are certainly not high-gain devices, but from my experiments tonight they make a noticeable difference in range. The metal foil covering works as well as solid metal at these frequencies.
I flew with these tonight in an open area I fly often. Normally, at about 2000ft, I begin to get FPV dropouts. (at about 200 feet height) and lose control a little beyond that. But with these simple reflectors, I was able to go to 3200 feet without ANY loss of FPV or control. I could have gone farther, but I ran out of open land and didn't want to push it. Try this, it works and you can make them tonight !
Here's a video I made that may show it better:
