,,,yes, I received this drawing from Egor on VK... ,,,and yet, this antenna is not very good...

,,,I know, I posted on VK, I want the dimensions...!!!

,,,after a certain number of disks(15), their number no longer matters, because the gain of the antenna increases insignificantly...!!!

Clanon, how do you make this practical antenna, isn't it a bit complicated...???

,,,it is also possible with slots in the active disk ....!!!

,,,certain users requested this and I have to comply...!!!

Of course !!!

75 ohm cable (for TV only), not for wireless(modem,antennas,etc) use...!!!

,,,a Bester antenna with other dimensions... Bester2442.cst ,,,and the practical realization of Egor- Free Wardriving...

two in one.cst

Method of cutting rounds...

DavidER,,why don't you look at this post on page 3...!!!

,,, yes, it could be that way(two in one)...!!!

,,,man, such a thing is not possible...!!!

2,4---2,7 GHz it"s not a limited band>>>!!!

,,,a Bester for an Offset...

200mm

,,,yes, it is possible, but the isolation between the two ports is not good, so two antennas with different polarizations(Horizontally+ Vertical) would be preferable...!!!

,,,this site may be of more help...!!! http://www.b-kainka.de/bastel95.htm

The theory of these antennas from the electrodynamic point of view is very difficult. At the moment, the parameters of such devices are selected empirically with the help of software systems electrodynamic simulation such as CST Microwave Studio... And here's one of my older projects.... By pasting a line of triangular adaptation can adjust impedance across the frequency range.

This dual band antenna is designed and made by RSRF. According to the datasheet, it operates between the frequency ranges of 600 to 960MHz and 1690 to 2700MHz with a modest gain of 6dBi and 9dBi respectively. These frequency bands pretty much covers all the cellular frequencies used for 3G and 4G LTE in North America. You can also use this antenna for low-band and mid-band 5G applications. As the low-band 5G lies between 600-850MHz and the mid-band 5G is between 2.5-3.7 GHz. Although this antenna only covers a small portion of the mid-band 5G frequency range.

,,,papus... if the antenna is out in the rain, you have to protect the antenna with a plastic case... ,,,or so...

The BDM-2 is a wave channel with crack initiation, and delay line is made of sequentially installed disk elements. Compared to classic antenna BDM new directed antenna BDM-2 is: More gain; Improved radiation pattern; More stable operating parameters; Greater reliability; Superior mechanical characteristics.
