This looks interesting.

FWIW I designed some hardware for a RSSI tracker a few years ago and it is now available on github:

The design can be 3d printed. I may get round to adding STL files, but for now the file in freecad/rssi_tracker.fcstd can be viewed using FreeCAD. You can export the bits from there for printing

The servo is GS3360BB

The ballrace is 42 mm od x 32 mm id x 7 mm thickness

The LCD is a standard module

The sliprings is also a standard size and available on ebay

it's diversity or two single, as others, but finally triying a Boscam D58-2.

Every start need to be centered? How can I set the center?
Autocenter is fine now.

After testing antennas and others, the signal of 2 receivers never are in the same values, one steps to 0.55-1.16 v and other 0.45 1.05v, and ever turns to the big one, must be calibrated or something or will never works properly, how to have same amount signal of pair of receivers, there is any way?
And which voltage is for each rssi value in the code?

There is going to be some difference in receivers,
one is going to be less sensitive than the other.
It will result in slight offset when tracker is centered on target
Find value that evens out RSSI

MIN and MAX RSSI values corresponding to 0% and 100% from receiver
See serial monitor
#define RSSI_MAX 400
#define RSSI_MIN 120

I am a noob...
Can anyone explain why I get this error when I try to compile:
no matching function for call to 'Timer::every(int, void (&)())'

Found it: Works only with timer libary 1.3 ...
