Depending on the type of coaxial cable, the length is calculated. For the sketch that I made, the coaxial cable used has the velocity factor=0,83 rg 402 has a velocity factor=0.74
-
This should be the connection with 50 ohm coaxial cable
-
Simple 5,6 GHz cross-polarization dipole antenna ,,, and with parabolic bottom box as reflector,,,
-
Efeksk, this is the best motor for drones?
-
We see what the antenna design is slightly modified based on the experience in the manufacture of the prototype was made a specific allocation of matching elements and active elements themselves. The concept remains the same.

Laptop connection
-
Why did you put this antenna?
-
An animation with the antenna to which a director has been added Impedance
-
And by changing the feed point
-

-
we'll see...!!!
-
Chil, expect to do that
-
That's it?,,,yes...!!! But it is best to welding directly the coaxial cable to the alimentation lines
-
I do not want to buy, I want to do it myself,,,!!!!
-
I found this on the internet and I would like to try to do it, what I need in the rest, much cheaper and easier to do (DIY) Please give me some indications .. !!!
-
At the 85 mm diameter parabola, the focus is 33.5mm
-
Of course, should be tried,,,,!!!!
-
And why not try with a 85mm diameter parabolic reflector from a methane gas cylinder bottom,,,??
-
But anyway ,these omnidirectional antennas have a very low directivity gain,,,!!!
-
Have you tried that kind of thing ... ??
-
About that, what do you think? With a parabolic reflector
-
Yes, and covers a wider bandwidth
-
Okay, I'm gonna try to do a simulation with this kind of antenna but the patches will be elliptical SOMETHING LIKE THAT,,,,
