This antenna is BDM-2 3g,4g mimo 2100MHz.  Central feed from the center 23mm at an angle of 90 ° tube diameter 10mm

I did mine a little wrong, instead of tubes I used plastic bushings, it was impossible to do that.  I ask the Admin to check the performance of this antenna HFSS.

without knowing the size and method of feeding, it is not necessary to talk about it.

How many kilometers does such an antenna take?

I don't know, maybe a maximum of 6km with a height of 3m and with direct visibility....???!!!!

Direct visibility is key for range. We tested 15y ago our cantennas in the field and it was no problem to establish a stable connection.
