Я работаю со всеми вариантами накладных, я проверяю. Это очень трудно держать центральный порт в нужных параметрах, на все участки.

Good morning, Admin!

Good morning, My FRIEND!

Erkin, you made a comparison in these antennas with Anritsu...???

 
 

[chilanzar2 85]

The first antenna is gone.
Echoing the Israeli antenna, written 3500-3800. If you need it, I can post it. Yesterday I found out. From me to you 1kg - 5dollars
The third. I think with round patches work better.

By the way, I do not speak English well. But, I perfectly know the Turkic languages of Central Asia and the Russian language. If I write badly, then do not laugh at me much. But, my hands are strong, and my head works well. I can fix almost everything. In addition to the nuclear power plan...

your doing great to me and I only speak English

the admin has help me also with WiFi antenna's 

I have learned more in this forum than anywhere else

[chilanzar2 85]

I'm glad to meet you. Write a lot, please. Here, in this forum everyone is happy.

[chilanzar2 85]

I bent the strips. What will this curvature lead to?

[Admin 2545]

Yes, but put it on Anritsu,,,,

[chilanzar2 85]

[Admin 2545]

Best so,,,,

 

I will do it....!!!!

 

[chilanzar2 85]

Almost does not change. I have fluoroplast
But, what will happen with the lateral radiation?

[Admin 2545]

what lateral radiation?

[chilanzar2 85]

I do not know what the side radiation is. But, good or bad it is - you know more than I do.

How to screen a box  of panel antenna with

Rexolite

Dielectric Constant(1MHZ-500GHz) = 2,53-2,62

 

 

As can be seen from the above images, the VSWR does not change significantly by attaching a Rexolite screen

 

Due to the relatively low dielectric constant and the high frequency range, this material is recommended for shielding the antenna panels.

[chilanzar2 85]

Is it Israeli production?

[Admin 2545]

Everywhere there's something like that ...!!!!

Dielectric Properties of Rexolite® - 
Outstanding! Rexolite® maintains a Dielectric Constant of 2.53 through 500Ghz with extremely low dissipation factors. Rexolite® is ideal for microwave lenses, microwave circuitry, antennae, coaxial cable connectors, sound transducers, TV satellite dishes & sonar lenses. Other applications for Rexolite® include nondestructive material testing devices, surveillance equipment, radar windows, radomes and missile guidance system housings. One interesting application for Rexolite® are radar lenses which are used in mapping the Earth's surface from fast, high altitude aircraft.

Ehhhh ...., Jomy, ....Jomy ..., we do not have such a  Rexolite-Pexolite. You have it in Europe, but we do not. Even, our Russian friends do not use this

невозможно не быть таковым в России....!!!

Требуются ... !!!

This is very expensive .. very expensive. The cost of the antenna is too expensive. We have about such sheets for the roof.

Policarbonat Rexolite  2000x1050x3 mm=350 rouble

,,, это дорого?

[chilanzar2 85]

350 rubles is 6-7 dollars.
Policarbonat Rexolite 2000x1050x3 mm = 7 $. Very cheap. We do not have such

[chilanzar2 85]

OK!  Yes, there is! Found. Look

But the difference here is more pronounced..
