Cyan in the control. Green is the Fpv. Try to maintain a clear line between Copter and Controller.
Unfortunately, the reply by Mrgs1 isn't exactly accurate. While the third sentence does provide correct info, the first two sentences don't. Before I explain, there's two things you need to always remember:
1) Data (flight, and we'll as photo/video) between ST16 & TH is "bidirectional". The ST16 transmits flight control info, as well as commands related to photo/video. As such, direct 'line of sight' is best. If you install a high-gain antenna on the ST16 and/or (preferably "and") external antenna on the TH, you will greatly increase signal strength between the two, and 'line of sight' becomes less important.
2) GPS Data, received by BOTH the ST16 & TH, is "unidirectional". The GPS signal strength is considerably greater than the signal between ST16 & TH, so, while 'line of sight' is still somewhat important (between ST16 & GPS satellite, and between TH & GPS satellite), it's less important than between the ST16 & TH.
That having been said, I believe the diagram shows the cyan as representative of the GPS signal, and green as the signal between ST16 & TH, in essence showing that it's best to have a clear path between each of the three (GPS satellite, ST16, and TH).

I made that in tryin to uderstand how they talked to one another ? I watch these videos, and know theres no A-B connection possible from what I'm seeing ? Just wondering how its done, is what intrests me ?

There are two radio frequencies in use. 2.4 and 5.8GHz. Wifi is used as the video carrier. 2.4 is the primary command and control frequency but in a pinch the 5.8 will substitute. The aircraft and the controller each have an independent GPS system.
You are bringing up questions that would be best answered by watching a few technical videos about radio frequency propagation and antennas on YouTube.

For the best control signal, the stick antennas should be pointed up and to the side slightly forming a V. The flat patch panel antenna should be pointed at the aircraft.
The GPS antenna on the ST16 is about 1" below the screen. It's the spot covered by my belly which affects the sat count on the ST16.

The diagram isn't a great representation of what's happening, as Steve Carr pointed out the GPS should another colour emanating from a different point on the controller not the antennas used for control and telemetry, and as PatR said if you want to indulge in wanting to know about howvsignal works do lots of research , myself personally I'm aware of what they do and how use them, sometimes blinding someone with lots of information as a new pilot doesn't always have a happy ending, reading the full manual on here, is probably more important, everything else can come later.
Thank you every one for giving me some insight on this ? What got me going on this is the clear line of sight between the controller, and the drone ? I watch these videos where theres no possible way the flier has a clear line of sight, which led to this question. I would like to do what the military does with their drones, but I dont have the resources at present.

From lots of direct experience, the military does what they do using many different frequencies, a lot more power, much better radio and antenna systems, including directional tracking antennas, and for some products satellite up/down links for data transfer. Their GPS systems are “unlocked” to provide much, much better accuracy and use encryption to protect from external signal interference/hijacking, requiring government authorization codes to access their system. They also employ vastly more sophisticated command and control firm and software and ground stations that make ours look like an old Atari Pong video game. The cameras and camera control functions generally exceed what most can imagine.

40 hours flight time! No more problems with batteries, and a great pyrotechnic display at the end.
Was just using the military thing as a referance point, what I'm really after is flying past my line of sight using only the camera , or the triangle on the st screen I know this can be done by watching these videos where you know theres no line of sight. I'll just learn as much as my brain can retain, and pracice a little at a time until I achieve what I'm after ?
Remember VLOS, best to keep your actions private, and definitely no bragging on YouTube, it not good for the hobby as a whole. My opinion only.
I guess you could, I caught that video somewhere, and was impressed with the inginuity Once I get better, going to give it a go ? Right now waiting for my cataracts to be done, but with the va its like pullin teeth. Right now I loose sight at like 230 and upwards in hieght in the late evening cant see the lights or strobes and in desend takes 3-5 secs till I regain a visual, I've also lost sight in distance but rtl brought her back.

It's a pretty rare-ish UAV pilot that hasn't been at least tempted to fly BVLOS if their aircraft is capable of doing so. Speaking only for myself, I have so far resisted that temptation but I admit that I have, on a couple of occasions, pushed it a bit...after 450 mtrs, or so, VLOS becomes marginal for my eyesight. (In the U.K. the max distance one can fly out is 500 mtrs. I have never flown out further than that).
To me, though, flying BVLOS isn't something that I need to do. Mainly because I plan my take-off points within my Area Of Operations such that flying BVLOS just isn't necessary, and am prepared to land and move my take-off point and take off again if that is necessary. Can you do that to avoid flying BVLOS?
Anyhow, If you do fly BVLOS don't get caught. As @Mrgs1 says, don't make a song and dance about it. Important not to make it obvious in any video posted on YouTube or similar. I believe there are people out there that trawl YouTube looking for such videos so that they can report illegal activities.
