The connector type should be SMA. N type connector is not used in FPV window.

How to design for 1200 MHz

You said you have a high gain value

ooow. Is not it possible

I did not understand

How do I build this

Yeah. If the final design does not work very well. I have not yet built a 1 mm pcb. I will give you information when I build it

Do you share this antebin building information?

Owww. What is this

Our 5800 MHz video transmitters have 600mW output power. With the best combination of antennas, a signal can be received at a maximum distance of 5 km. I've never heard of anyone going farther. But even 5KM distance is very difficult. Few people have reached these distances. So we have to design a good antenna

We use 1.2 GHz system for long distance FPV flight. The distance in these systems is relatively more comfortable. It is much more comfortable because it is inversely proportional to the frequency. But the picture quality is worse than the 5800 MHz frequency. Also, in 1.2 GHz systems, the transmitters have more dimensions and weights. And the antennas are bigger. Quadrocopter is not a convenient frequency. However, long distance can be used in large airplanes. I am using a 1240 MHz Bi-Quad Antenna in the video receiver system for a distance of 47 km.

I have to test

hımm. Denemek lazım.

I've never used. Which one is more productive

I do not understand exactly what you ask

I will build tonight

Please send me the IGS file.

That's it. Has the PCB Measurement changed?

Which antenna is more effective at 5800 MHz frequency over long distances

Oowwww. Ok

Component specified as abs. FR4 Epoxy material. It's very different from plastic material. No choice between epoxi options

Why did the values change?

These measurements were made without bolts. I will send you measurements made when you have bolts

I would like to manufacture this design with fr4 of 1mm thickness. What about you?
