,,,да...!!!

2 антенны вместе? Или 1?

[Admin 2628]

,,,try as you like...I think two is better...!!!

,,,испытайте как хотите...Я думаю, два лучше...!!!

What is the best way to position 2 antennas? Vertical, horizontal?

[Admin 2628]

,,,one antenna with horizontal polarization and the other with vertical polarization...!!!

ДэвидЭР,

,,,эта антенна Bester только для 50 Ом, для 75 Ом нужны другие размеры для питания...!!!

Is it possible to simulate a 75 ohm antenna?

[Admin 2628]

,,, yes it is possible, I told you before...!!!

,,, да это возможно, я же говорил тебе раньше...!!!

Fine. Will the drawing be ready?

[Admin 2628]

,,,maybe later...!!!

[DavidER 2]

Where is the horizontal and vertical polarization to place 2 antennas?

[Admin 2628]

110---143mm

[DavidER 2]

Have you modeled a 75 ohm antenna?

,,, may I try today ... !!!

[Admin 2628]

DavidER,finally, I managed to complete this antenna,.with 75 0hm impedance(1,95---2,2 GHz)...

[Admin 2628]

,,, another version of Bester Antenna by Alexander Bars....

 

and positioning this antenna in the focus of an offset parabolic dish

[Admin 2628]

,,,another type of Bester Antenna ...

Do you have a drawing for the antenna?

[Admin 2628]

...the first image is for the (central) frequency of 2600 MHz (in red) and the second for the (central) frequency of 2100 MHz

[DavidER 2]

And besides the frequency 2500-2700, is 1800 used?

[Admin 2628]

 

 

Anyway, these dimensions I gave you must be verified by simulation.

Will a 6-8mm stud with nuts work?

,,,,maybe, but simulations need to be done...!!!

[DavidER 2]

Okay, check it out.

[DavidER 2]

Is an n-male pigtail suitable for a length of 15-25 mm?

[Admin 2628]

I think it's possible, try it...!!!
