Diary of a solid man-a beginner antennae in excess of high frequencies.

[chilanzar2 85]

I can repair split air conditioners, satellite dishes, conduct electrical wiring. I can fix cars, and a lot more that I can
Recently, I put amplifiers gsm-3g. Grateful to these my professions, I did not become rich. But, I live in prosperity. In my refrigerator sometimes there are cheese, fish, sausage, and much more. Thanks God!
But, recently there was a client asking for a lot of wimax2300-2400. And I, understanding nothing in excess of high frequencies, tried to understand the theory and practice of these antennas. How do I do it - I'll write a little in this thread.

Ok, Erkin, but it's important to know that these WIMAX antennas have a circular polarization...

Jomy, on the second photo, an antenna-wimax - with circular polarization?

Yes, of course, and as a special fact the circular polarization antenna has a minus of 2-3dBi to the linear polarized antenna

By the way, members of the forum, I must note that in search of information about extra high-frequency information, I have registered many such thematic forums. But only in this forum I get a lot of help. For this I want to thank the respected Admin a lot. He leads me in the world of antennas.

[Admin 2578]

And for this, I think the positioning of your antenna should be changed.(repositioned)

Admin, I can not find nylon screws and bolts.
I have to use metal screws. How many different sizes do metal-screws use, unlike nylon?

Dear forum users, I want to note that I have been writing with the respected Admini for many hundreds of times - both in other forums and in this forum, even through private.
Antennas in excess of high frequencies - this is a very complicated thing. I did not think so in the past.

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...

[chilanzar2 85]

Today I found in the bazaar all sorts of little things here are such things - I'm starting to prepare the screws myself. To my good luck - this nylon thread - there is fluoroplastic

[Admin 2578]

ERKIN, after my simulations, it looks like metal screws and spacers are better than plastic ones...

 

[chilanzar2 85]

We do not have such details. I am forced to make it myself. We try to make with our friend. We'll create this detail - I'll post it right away

[Admin 2578]

it's very simple,,,!!!
 

 

 

[Admin 2578]

But, as simple as possible, it is with them...

 

 

[chilanzar2 85]

Thank God! We collected this device.

[Admin 2578]

 Bravo, excellent Erkin ... !!

Can you test with Anritsu ... ??

[Admin 2578]

Attention, if you mount the four screws in reverse, with them you can also fit the plastic cover...!!!!

 

[chilanzar2 85]

Now I will check on Antritsu. Fluoroplastic F4

[Admin 2578]

Success...!!!

This is the data from the last connector.

My students! But, I myself am a student in high-frequency antennas
With love from Tashkent

[Admin 2578]

I like, very nice everything ... !!!

[Admin 2578]

The last option, I'm sending you the * dxf file

 

[chilanzar2 85]

I try to understand this device. I need to put 2300-2500
