,,, yes, it seems you are right...
-
I don't know, let's see ... !!!
-
,,, no, but I can do something about ... !!! ,,, it must be known that this antenna is a fake...!!!
-
Zeta F MIMO 20 dBi
-
,,,why do not you try metal disk loaded helical antenna...???
-
,,,yes...!!!
-
,,, Clanon, display the dimensions please .. !!!!
-
,,, this antenna does not work well and is not the original...!!!

Operating in the 2,4GHz band, the antenna panel integrates a state-of-the-art, dual-polarized smart antenna that offers blazingly fast and highly reliability connectivity across long distances The reflector is provided with CPC (Compound Parabolic Curve) walls.

,,,okay,I will try....!!! ,,, but it would be better to try this...
-
,,,to see this...
-
,,, try and you will see ... !!!
-
,,, if dielectric foam(polystyrene) is applied between the patches, the dimensions of the antenna can be reduced...
-
OOPS,,, this antenna does not work...
-
Clanon, this antenna is very difficult to build ... !! ,,,try to post something simpler...DIY...!!! ,,,like this...https://emagtech.com/wiki/index.php/Application_Note_3:_Designing_A_Slot-Coupled_Patch_Antenna_Array_With_A_Corporate_Feed_Network_Using_EM.Picasso
-
,,, can you give some dimensions ... ?? ,,, and what the vibrator looks like inside...???
-
,,, dimensions, please ... !!! ,,, or, I may need to install the NEC program again...!!!
-
,,, watching this video, I considered it necessary to try to design a Bester antenna made of FR4 fiberglass.... ,,, so I present below the simulation designed and sketches for making the antenna....
-
-
,,, okay, it's enough to just give the dimensions...!!!
-
,,, there is not much difference between the two boom diameters(4mm or 8mm), although preferably it would be a diameter of 10(15) mm made of threaded screw and pipe and patches of galvanized sheet with a thickness of 0.5-1mm....!!! ,,,,increasing the boom diameter ensures a wider frequency band...!!!
-
,,,double band no, but broadband yes...!!!

Efficient feed for offset reflector antennas for 4G networks (LTE1800) support MIMO technology. F=1.7-1.9 GHz, the Resulting KU with reflector up to 27dBi. Connector type - N-female (50 Ohm). Own gain, dBi=9-10 The width of the days in the H-plane by level -10dB, hail=110÷120 Width days in E-ploskosti level -10dB, hail=90÷96 Isolation between inputs of the antenna, not less, dB=28 Input impedance, Ohm=50 SWR in the frequency range, not more=1,5 Polarization...vertical+horizontal Overall dimensions, m 0, 145x0, 145 x0, 145

However, this latest optimization has a wider frequency band... ,,, and a better gain in directivity....
