SUPER SIMPLE 5.8GHz RSSI ANTENNA TRACKER


Hi
I built an antenna tracker around 5.8GHz RC540R diversity video receiver. It uses an Arduino, 5V voltage regulator, 9g servo and a couple of 3d printed parts. Today I tested it for the first time with 25mW vtx and it worked well

You can download the software here:
https://github.com/andreiva/simple-rssi-antenna-tracker

Project also includes some screenshots and servo-mount STL files for 3D printing.

Awesome work! could this be expanded for vertical tracking as well?

This is for tracking at distance only, not to fly around and over head

I guess it kinda depends on how "simple" you want to keep it.

Like renatoa points out, how often do you fly really high above your head?

Technically...sure it's possible but tricky, because there's only two antennas. With some math and a few trade offs it can be done.

TBS Crossfire or DragonLink?
Is this similar to the 5.8 "RSSI ProTracker"
being sold as of now?
($240.00)
It uses the 5.8ghz channel on your VidTX (plane)

Actually, antenna trackers were first time primarily developed for proximity flying around, and LOTS of overhead passes, not for long range !
The farther you fly, the easier is to aim manually, and no need for a tracker.
The explanation is simple: people who developed first antenna tracker want to fly legally using the legal 25mW power, allowing at most 200 meters with an omni antenna.
So a directiional antenna was a must to achieve at least 500 meters for a bit of fun. Thus they were limited to fly in 500 meters circles, style that imposed a tracker.

Yes, basically they both are video receivers on top of a servo. RSSI ProTracker is fancier though, it has an LCD, video amplifier for long cables, sturdy casing.

Simple tracker is just the RC540R receiver with Arduino in it and a servo. If you already have the RC540R it's a simple mod to make. And you can still use it in conventional way, just unplug the servo.

I think you got my point now. I totally agree with you.

does it have to be a diversity receiver..
can i use a non div. rx ..

you need two of those and it should work!

No, it doesn't have to be diversity receiver. All you need is two receivers with RSSI output and it should work. Then only one receiver would be connected to a display or googles and the other would be used for RSSI measurement and there won't be diversity switching.

the ludicrous way to implement this concept

even the idea to place a CL in the middle is wrong, will not help for overhead passes, because there is a signal hole straight in the CL center... bummer

I've been fascinated with this VideoRx you mentioned
I don't know if its a good one or not?

Seems like HK is sending these out for reviews.
Hope they send you one
