,,,, metalic spacer...!!! ,,, will it work without these 4 pcs cylinders,,,, but the frequency band will narrow...!!!
-
... for that... it"s this adaptation lines...
-
,,,, preferably 0.5mm, but 0.25 ---- 0.8(1)mm can be used The thickness does not matter much.
-
,,,spacers not plastic,metal...
-
diameter=54mm at 8mm height but you don't have piece B...!!!
-
There is nothing solderd, yet there is bending at 90 gr and riveter..!!!
-
,,, this is how the central connection point should look...!!! ,,, dude, you are missing piece B...!!!
-
,,, 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...!!!
-
,,,very good, good luck ...!!!
-
,,,61mm....!!!

A novel rectangular microstrip patch antenna for ultrawideband(UWB) applications is proposed. The ultrawide frequency response is achieved by determining the dimensions of the radiating patch of antenna . Besides a directive radiation pattern, high efficiency and a constant gain is achieved in the operating bandwidth.
-
,,, if "v" is diameter, then yes...!!!
-
,,, a user on this forum(ct2iok) is interested in this yagi antenna..
-
1) yes,,, but the vibrator must to be weldable,..!!! 2) yes,,,, watch this forum carefully..!!!
-
,,,like this...!!!???
-
,,,and this it"s UMO-3F MIMO2x2 for offset parabola...??? Just added a protective solder mask.. ,,,and on YouTube...
-
No, it's a simple connector...!!!

GSM/LTE 1800MHz UL=1710-1785MHz DL=1805-1880MHz Fm=1795MHz
-
,,,download(DL) it"s verry good but why upload(UL) it"s poor...???!!!
-
,,, a variant with more exact dimensions ... !!! ", and if you want a cross-polarization you can use this solution...
-
I don't understand what you mean...!!!
-
, not only the dimensions of the patches, but also the distance between the reflector and them...!!!
-
I think this is better...
-
,,,may be 1,8GHz and 2,6GHz..!!!
-
,,, yes, those 4 curved dipoles are for lower frequencies..and they seem to have adaptive loops on the PCB.!!!
