1001 trifles for self-made antennas

[chilanzar2 85]

 

Admin, what diameters and length are needed for the manufacture of antennas plastic bolts-nuts, spacers, washers? Usually.

 

I look at the aliexpress, there are many such plastics. How do you do when you need plastic products? Thanks for the answer.

[Admin 2561]

I do not understand what you mean?

Antennas are short-circuited and not short-circuited. On open, not short-circuited antennas, what plastic bolts-nuts-spacers to use? There are different platters, and different sizes

It has been determined that the nylon spacers between the patch element and the reflector originally shown in the drawings, degrade the performance of the antenna. It is suggested that the spacers are not installed. 

[chilanzar2 85]

So, the thinner the spacer, the better? On aliexpress buy such nylon bolts-nuts-spacers, or, no? 

In Uzbekistan, there are no such details

Expanded Polystyrene Foam: the best spacer

 the permittivity is 1.02 – 1.04 with a loss factor less.

Only ordered nylon bolts-nuts-spacers. In the meantime, so do mimo2600. It's ridiculous.

[Admin 2561]

It's not ridiculous, it's really good, and so ... tell me the results...!!!!

 

But tell me why the question marks...???????????????????, appear in the first picture

Ooo, this is when the Cyrillic alphabet is written, then "????" Appear .. I apologize, did not notice

[chilanzar2 85]

 

No results for mimo2600. Because sma, F-male and other connectors are not present. Today crc9 & ts9 came. I collect all the necessary 1000 & 1 small things.

You liked my avatar! I will try to make sure that my movements please you. You are the guru in the world of antennas! =======================

With such nylon bolt-nuts, you can achieve better results. I think so.
