,,,try and you will see...with PCB you need other dimensions...!!!

Can I add more directors for more gain.or it starts to lose it?

[Admin 2545]

Yes of course...!!

Thanks....

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.

Hello. Who has the correct drawing with dimensions for bdm 1800-2100 mimo and 50 ohm cable?

bester did not produce such an antenna

[Admin 2545]

300 MHz...???,,,, the frequency bandwidth is rather large...!!!!

1800 - 1700...1900

2100 - 1900...2200

500 MHz 

 

 

But... 

[Admin 2545]

,,,,but ....only with three elements...!!!!

,,,and with ARINST Measuring equipment, something completely different comes out...!!!

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

[Admin 2545]

,,, well, then you answer "farad84"...!!!!

Construction in metal. Works good.

 

Hi, any isolation applied somewhere?

[Admin 2545]

,,, without insulation between the elements of the antenna...!!!

I will try to make a simulation for a 75 Ohm cable..!!

[Admin 2545]

,,, this would be the antenna for 75 ohm input impedance....!!!

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....???!!!!

[Dr. Pepper 58]

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.
