Chil, I think it's all M3 screw, but with a step more than 0.5mm (0.6 ... 0.7mmm))

,,,good, another constructive form of this antenna, with built-in modem...

L4G DESPITE / 15 dBi - team of two multi-band antennas for data transmission over the cellular network. L4G DESPITE the fact intended for operation of different channels of transmission and reception. Works in all existing and future networks in Poland and Europe. Operating frequency ranges: 800, 900, 1800, 2100 2300, 2600 MHz. Supported technologies: • 4G LTE MIMO Dual Carrier HSPA + Dual Carrier • 4G, DESPITE the 2300MHz and 2600MHz • 3G, 2G • Also supports wi-fi Wireless 2400MHz on two antennas. Application: • All modems and routers, 4G LTE, HSPA +, WCDMA, UMTS, HSPA, 3G, 2G/GSM • Allows you to build a reliable connection service high speed broadband Internet access. • Required for areas with a weak to medium signal level, and in urban environments with dense buildings.. This simplifies the installation of the antenna, even people who do not know technical problems.

Good, you are right, but you know how the logarithmic dipoles are synphased...!!!??? It is a system of two directional antennas, external, on the contrary, polarized, designed for data transmission in cellular networks in the DC (Dual Carrier). Two antennas installed on the system, X-pol, and provide excellent separation between the channels of the MIMO transmission. Team reduces thereby the number of errors in the signal, and raised to a higher level of data transfer rate. Perfectly solves the problem when the signal is too weak for proper operation of the modem or repetera. Modern design, log-per construction, provides a high income with a very wide range of moves frequency.

H4G antenna, antenna gain 15dBi. This is an external antenna, highly directional, designed for mobile communication systems LTE, UMTS, HSPA+, operating in the range of 1.8-2.2 GHz. Perfectly resolves issue where the signal 4G/3G is too weak for proper operation of the modem or repeater. Just attach the antenna to the modem to improve signal strength and surf the Internet. Feature of antenna: circular polarized antenna H4G does not require attention to correct installation polarity antenna as in dipole antennas of the type Yagi-UDA, or panel. This simplifies installation of the antenna, even people who do not know technical problems. Other features: Modern compact design, helicalna construction, gives a high gain in a wide band frequency is moved. Hermetic and durable casing to withstand extreme weather conditions, which guarantees a long and reliable performance. Mounting bracket allows wide range of diameters of used masts. The mounting bracket allows the tilt of the antenna 50 degrees in the vertical plane, a parameter important in mountainous terrain. Uses high-quality materials - copper, aluminum, galvanized steel, plastics change.

,,,and here's how the BFRing antenna behaves in a parabolic dish with a diameter of 1800mm and f / D = 0.43...

,,,good, and the results, after simulations.... Dimensions...

Good, these are the dimensions on the SBF antenna above,,, ,,,and the simulations...

The antenna on youtube...

,,,create a cardioide... http://mathcurve.com/courbes2d/cardioid/cardioid.shtml

,,,see this...!!! http://mathcurve.com/courbes2d/cardioid/cardioid.shtml

Poor polarization... in the animation field, it is seen that the antenna is turned "paleoliticheskoi" polarization, the lower patch remains in phase from the top to the same. in short, power is not good. it is necessary to draw a line at right angles to the edge of the patch, and not to the line between the patch and screen.

by Vodkaman user... "Useful this thing or not, you decide, but I was curious to Tinker. The basis is the biggest RK 240x195mm. Material - galvanized, 0.5 mm copper wire 1.5 mm. Box (cover) only such other firm requires recalculation." Achievement practice ..????? PQ1sf.pdf

,,, here, on this forum ... !!! "chilanzar2"

I think Chilanzar could inform you best...!!! " it might be 0.5mm...!!!

These are the component parts of the PCB antenna... Irg, please, if you can post the dimensions to them...!!!

ok, I see no one guess ... !!!

Another practical achievement...

,,,this works too.... Some people have tried it but without any noticeable results...

IRG, show the movie on youtube...!!!

,,,from where it"s "youtube"...??

,,,,something like that...

Acri brother, please excuse me that I did not pay too much attention to this type of MiMo antenna, but now I think this is the best option...

Based on this adaptation system, Yagi 900MHz-1800MHz antennas can be built good, and this is a practical achievement...
