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

236 posts in this topic

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...

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.

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...:)

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

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

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