Hi,

As you know I succesfully tested WIFI+S Range Extender. It's giving me best results than famous Xiaomi Repeater v2. WIFI+S Range Extender vs Xiami WIFI Repeater

But I would like to go one step beyond I decided adding a Parabolic Wifi Reflector for better range and performance. I performed this task in the past for Xiaomi, remember: WIFI reflector for improving Tello range

I faced the problem WIFI+S has two antennas four centimeters apart. I find and download this template from "Corrugator Supercilii" at instructables.com:

DIY WIFI Antenna Reception Booster

I started worked on it, adding a four centimeters width non-used flat area between both antenas. That way each half of reflector feeds only one antenna. I have no previous experience into Wifi reflector designing but I hope my pattern works

Here are my modified templates for WIFI+S Range Extender. Ensure you print them into a normalized A4 size paper sheet. Space between holes must be four centimeters. Click over images for a full-size file download:

Some pictures final result:

3453

3454

3455

I hope performing flight tests soon.

Raul.

Hi,

Finally, Parabolic reflector test finished.

I achieved an average 25% range improvement when using Parabolic reflector into WIFI+S. Image quality improves similar way.

This results are very close previously obtained when testing Parabolic reflector for Xiaomi Wifi repeater some months ago. At that time I got 20-30% range improvement WIFI reflector for improving Tello range using Xiaomi WIFI repeater

As you must know, this kind of test are hard to perform. I need to perform lot of flights until getting consistent results.

Anyway, let me show a couple of images as a proof:

First, WIFI+S without Parabolic reflector. This february flight I got 291 meters. I reported it here WIFI+S Range Extender vs Xiami WIFI Repeater

Then, WIFI+S with Parabolic reflector. Yesterday afternoon I got an amazing 364 meters. Incredible range for a residential area full of neighbors WIFI interference. As said, a 24% range improvement.

Take into account you should flight in front of Parabolic Reflector. No magic as range improvement achieved at expense of losing range backwards/sideways.

I hope it helps

Raul.
