Principle of Yagi Antenna

This is a post from our forum friends.

I don't know what the environment is.

One operation...

This is a model. Just follow the wavelength operation instructions above. This is relatively simple. What we need is engineering applications combined with actual needs.

I found this working point. I got 0.95G

So I didn't pay much attention to it. It still needs to be optimized.

The gain did not achieve the desired effect.

Not sharp

Is there any big guy who can give some advice?

Those who play with radio frequency are already big shots, and they still want guidance from big shots.

Where is 950MHz used? Sharing WIFI over long distances can be easily solved with a Yagi antenna.

This comprehensive and detailed knowledge point is something you will never be able to master completely. You will have to learn it and return it even if you don’t use it. So I still need to ask for advice.

Modify the spacing of the director array.

Do you dare to launch it?

A small change to the antenna has such a big impact.

Be careful with this...

They did it secretly. The Radio Commission came and shut it down.
