,,, 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...

Offset irradiator in the range of 1670-1720 MHz. Ra=50 Ohms. GAIN=10 dBi. It is intended for use as part of equipment (mirror antennas) for receiving L-band RCPH signals from geostationary satellites. Electrical characteristics Operating frequency range, MHz 1670 - 1720 Native gain, dBi 10 The resulting CU and radiation pattern width in terms of level is 3 dB for different diameters of an offset parabolic antenna (at a frequency of 1695 MHz) with an F/D ratio of 0.5 0.55 m 17,5dBi 21 gr. 0,6 m 18,6dBi 19,5 gr. 0.9 m 21,7dBi 14 gr. 1.3 m 25dBi 9 gr. 1.5 m 26,4dBi 8 gr.

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.

The AX-2017PF panel antenna is intended for use in a set with 3G modems (routers). The antenna type is common-mode array. It is recommended for use at the borders of service areas, when the 3G signal level is weak and unstable, as well as in the case of a long connecting cable between the modem and the antenna installation point. The AX-2017PF is a version of the AX-2017P antenna, but only for a 75 ohm cable. The antenna uses an F-female connector (a conventional TV connector with a thread), which makes it possible to make cable assemblies directly by the user without resorting to the help of specialists, without using special tools. By using a SAT703 TV cable instead of a 50 ohm cable, you can save a lot of money . Electrical characteristics Operating frequency range, MHz 1900-2200 Gain, dBi 16÷17 Bottom width in the H-plane, deg 32÷40 Bottom width in the E-plane, deg 16÷19 Side lobe level, dB max -13 Forward / backward ratio, dB not less 20 Input impedance, Ohms 75 SWR in the operating frequency range, max. 1,5 Permissible power, W 10 Polarisation vertical/horizontal Mechanical characteristics Weight with mounting, g 1800 Overall dimensions without mounting, m 0. 45x0. 24x0. 05 Connector F-female Antenna Material steel, galvanized steel Protective coating powdered polymer paint Material of the protective box Polycarbonate+ABS

,,, modified version with bent reflector... patch with bent line.cst

,,, maybe so ...

I think the galvanized sheet is the best...!!!!

,,, a constructive variant of the user "com666" ... !!!

,,, the antenna dimensions of the user "com666"....
