,,,not! but why do you want to use 75 Ohm coax cable... SOMETHING LIKE THIS IS NOT USED...!!!???

,,,another version...

,,,yes, it fits...!!!! ,,,and in the focus of an offset disc...

,,,maybe this one...!!!

,,,the antennas after the Cantennator calculator, are not very good..!!!

,,,yes, but it must be taken into account that for the frequency of 900 MHz, the diameter of the reflector is around 250mm...!!!

,,,could you build something like this...???

>>>a good BESTER antenna...

,,, these types of coaxial cable would be...

,,, the best solution is to use an offset dish with a Bester antenna, or you can try the Batwing antenna for the two frequencies...!!! ,,,maybe even this...

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

Hi buddy, you can try this...!!! DS SIMULIA CST STUDIO SUITE 2022 Linux https://downloadlynet.ir/2020/13/2905/03/cst-studio-suite/00/?#/2905-ds-simul-092350055002.html

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

Yes

Of course...!!!

,,, yes it is possible with 9.525 diameter spacer pipes...!!!

Well, almost a year later we released this new version of the 32-bit branch for computers that are either very old or that, even supporting 64-bit, no longer measure up in modern systems. https://foro.seguridadwireless.net/live-wifislax/wifiway32-1-2-version-final-para-descarga/msg375187/?topicseen#msg375187

,,,better like this...!!!

,,,these are the dimensions...

,,,where did you get this picture from? ,,,but I think this is it...!!!

In telecommunications, a collinear antenna array is an array of dipole antennas mounted in such a manner that the corresponding elements of each antenna are parallel and collinear, that is they are located along a common line or axis. Collinear arrays of dipoles are high gain omnidirectional antennas. A dipole has an omnidirectional radiation pattern when in free space and not influenced by any other conductors in that it radiates equal radio power in all azimuthal directions perpendicular to the antenna, with the signal strength dropping to zero on the antenna axis. The purpose of stacking multiple dipoles in a vertical collinear array is to increase the power radiated in horizontal directions and reduce the power radiated into the sky or down toward the earth, where it is wasted. They radiate vertically polarized radio waves. Theoretically, when stacking idealised lossless dipole antennas in such a fashion, doubling their number will produce double the gain, with an increase of 3.01 dB. In practice, the gain realized will be below this due to imperfect radiation spread and losses.

,,,something like that... ,,,or so...
