Hello dear members of this very great forum, separate huge appreciation to Admin.

I'm wondering if anyone can help where is the second part round pair of cicrles.

By all the sudden, I started thinking about it when I got the two same details in hand and wondered how was I suppose to do soldering job here. 

Any help is really appreciated 

Best regards, Rizo

,,, good achievement, congratulations for AmateurRadist ...!!!

,,nothing is welded, bent at 90 degrees and then riveted with the riveter...!!!

 

PS

,, look once again, on my previous post...!!!

To say the truth, I got two same parts and somehow managed to solder(weld) them together and got this. However second connection's standing wave ratio is way higher, around 4-6.

,,, this is how the central connection point should look...!!!

 

,,, dude, you are missing piece B...!!!

Is it soldered by robots? I'm having hard time soldering this. I think this may be reason for high vswr. Also the machine didn't cut edges well, but I polished them to be ideally smooth. Hope next time it will work, it's almost cost of new one :) but I believe this experience is priceless :)

There is nothing solderd, yet there is bending at 90 gr and riveter..!!!

Sure I got this, I bended and riveted, then soldered the part with small hole to connector's pin. It's hard because there's so little space that soldering gun can't reach. 

2) are there 4pieces cylinders over this? What's distance height from bottom they should be located? Will it have good gain without them also? If not what's their diameter?

Any help appreciated 

Best regards, Rizo

 diameter=54mm at 8mm height

but you don't have piece B...!!!

I cut piece A and created piece B with welding parts :)

If spacers is plastic, is it okay?

,,,, preferably 0.5mm, but 0.25 ---- 0.8(1)mm can be used

The thickness does not matter much.

how these cylinders should be placed, using 8mm metal or plastic spacer. And will it work without these 4 pcs cylinders

1800-2600 MHz

,,, now I work on this ..!!!

22.jpg

How come? It's 1700-2200mhz, without cylinders will narrow to 1700-2600mhz? 

2) these cylinders are not connected to main antenna in original version, why should I connect it to main part by metal spacer?

 I will try the simulation with and without the director cylinders..!!!

Greetings to radists

In second attempt/episode of "that looks easy, let's do it instead of buying" reality show I finally got 2.5 vswr max in main port and surprisingly amazing 1.8 vswr in second port without cylinders. 

I suppose vswr in main port is high due to bad soldering, after bending it's like mission impossible to reach this pin. Before bending, soldering is easy but hard to bend. 

I will try once more, are there any other things I need to consider to get lower vswr in main port i may be not keep in mind. Any suggestions are welcomed

Huge thanks to admin for his hints :)

But it must be adjusted at 1800 MHz, if it's possible could you present CST file.

Yes, I once studied at the university on the subject of "antenna-feeder devices"
