,,, yes, on this forum you can find enough ways to connect 4 antennas..!!!

Юрий 26,,,, say in English please ... !!!

,,,yes,1800MHz(1750-1950)...!!!

Юрий 26,,, the dimensions in red are for you...

,,,say it in English..!! ,,, is interested in the dimensions of the dipole in detail...!!! ,,, for construction see this,,,https://www.lan23.ru/forum/node/10024/page13

,,, okay, but I need some dimensions...!!!

,,, maybe this would be another method...

,,, thanks Antonius, no, the performance of the antenna is not influenced by this method of soldering .. !!! ,,, please ,attach a few words for explanation to each image above...!!!

,,, adenden, these are the dimensions...

,,,wrong...!!!

,,,,this is the 2442 MHz antenna... gnutika60.cst

,,, give up the nuts and put spacers from the 10mm diameter pipe and M8 screw inside...!!!

,,,,adeden,speak in English please...!!!

,,, this is the real Petra-9 2x2 Box antenna...

Delta 3G/4G-20 MIMO antenna UNIVERSAL panel broadband MIMO 3G-4G antenna The operating frequency range is 1700-2700 MHz. Designed to amplify 3G (1900-2170 MHz) and 4G LTE (Band 3-FDD 1800 and Band 7-FDD 2600) signals. The Delta 3G / 4G MIMO antenna with a Gain Of 20 dBi provides maximum connection speed and stable network operation in conditions of maximum distance from base stations. Universal Delta 3G-4G MIMO 20 antenna is suitable for MegaFon, Beeline, MTS, Yota, Tele2 Telecom operators The universal 3G/4G antenna is connected to a modem or router via cable assemblies and an antenna adapter, and allows the antenna to work simultaneously in both 3G and 4G networks. Cable assemblies of the desired length and necessary adapters can also be purchased from us.

GSM refers to the networks of the second generation (2 Generation) (1G — analog cellular, 2G — digital cellular, 3G — wideband digital cellular, dial-up multi-purpose computer networks including the Internet). Mobile phones come with support 4 frequencies: 850 MHz, 900 MHz, 1800 MHz, 1900 MHz. Below is a 2x2 MIMO antenna panel on 1800 MHz

,,, these are the dimensions(in Red) for 2.3 GHz...

This MiMo antenna was made by the user "com666" and has a circular polarization(RHCP+LHCP)... According to simulation the antenna is good, but isolation between ports is not the best...!!!

In the 1926, Dr. Shintaro Uda and Dr. Hidetsugu Yagi of the Tohoku Imperial University invented a directional antenna system consisting of an array of coupled parallel dipoles. The second dipole in the Yagi-Uda array is the only driven element with applied input/output source feed, all the others interact by mutual coupling since receive and reradiate electromagnetic energy; they act as parasitic elements by induced current. It is assumed that an antenna is a passive reciprocal device, then may used either for transmission or for reception of the electromagnetic energy: this well applies to Yagi-Uda also. The simplest or minimal Yagi-Uda antenna has at least two parasitic elements behind the Driven Element (DE); the antenna with only one parasitic element as Reflector element (Ref) is generally called Yagi antenna. This happens when the electrical length of the parasitic element is greater than the driven element.
