Catherine antenna

[Antonius 17]

Hi admins. I'm trying to assemble a 4g antenna, for the frequencies 1800, 2100 and 2300, with this Catherine Antenna. Can you help me simulate it? Thank you.

,,, okay, but I need some dimensions...!!!

Kurang lebih seperti ini yang bisa saya buat.

 This is more or less what I can do.

,,,say it in English..!!

,,, is interested in the dimensions of the dipole in detail...!!!

,,, for construction see this,,,https://www.lan23.ru/forum/node/10024/page13

Sorry. Yes, the dimensions are the same. Right now in my country there is a lot of talk about the Catherine antenna. Looks very interesting in the attachment. To maximize the performance of this antenna is it enough to add a 120 mm reflector?

I have tried to connect this antenna to a 2.4 Ghz wifi router. Antenna works fine. Can master Joymi simulate this antenna for 2.4 Ghz frequency, and how many dbi gain is obtained? Thank you in advance.

,,,only if you give me all the dimensions on the antenna....!!!

the Blue and RED coax should be NEW CABLES straight to the card...(if possible to solder in there)

High losses

,,, another situation would be if SMA connectors were attached to the REFLECT0R...!!!

Okay. I will try to give the size in the picture. It might take some time.

It is very difficult. I came up with a much simpler one. For making with your own hands. Simplicity of design and availability of materials.

Use it.

These are the measurements I got.

Pre made , wonderful...and all dimensions should be available before buying it , for trial and error 

Jomy the supports seems to be PTFE (teflon)

It work in 2100 mhz

,,, another configuration ...

focus point is important (distance to reflector) some mm make a huge difference...

did you try with antenna (reflector ) at 90 degrees...VERTICAL...?
