,,, these are the test results...!!!

,, ,,but isn't the antenna a bit big ... ??

,,, and for what frequencies do you want J Pole antenna to work ..? /

,,, what program, for simulation or for measurement of antennas ... ??

,,, welcome back to this forum my friend ... !!!! ,,, you still have to tell me the dimensions on the coil...!!!

I think these Bester antenna sizes ensure a higher bandwidth ,,, or with 12 elements...

The Ubiquiti NanoStation M5 all-weather access point is a successful solution for transmitting traffic at a speed of 150 Mb / s over a distance of up to 15 km and a frequency of 5 GHz. Frequency 5470-5825 MHz Antenna Built-in 2x2 MIMO (4.9-5.9 MHz) Gain 14,6–16,1 dBi Polarisation vertical and horizontal Cross-polarisation> 22dB SWR1,6 A single antenna can be used, either with horizontal polarization or with vertical polarization.

,,, you can build such an antenna....???

,,,,for outdoor antenna I think you should read this post ... !!!! https://www.reddit.com/r/tmobileisp/comments/l93wym/how_to_use_an_external_antenna_on_the_tmobile/ ,,,and this...

,,, after several optimizations I got this...

,,, maybe it's something like that ... !!!???

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

That's what the vibrator looks like...

,,, what happens if you combine a LINWLAN2 antenna with a Bester antenna ... !!! ???

,,, the dimensions are in the above simulation .... !!!

,,, it can work, but for what frequency in 4G .. ?? ,,,for this antenna you can give some dimensions ... ???

,,yes, it's true, the distance between directors and the diameter of the directors, it would be best, I think it is Lambda / Pi = 0,318*Lambda...!!!

(DTA)Double Triangular Antenna is one of the best zig-zag antenna. Her canvas in contrast to the previously discussed antenna differs in that instead of two rhombuses consists of two triangular frames. The antenna pattern in the horizontal plane with no reflector is an eight The input impedance of the antenna in the receive frequency range depends on the antenna dimensions and its forms, from the placement of terminals to which is connected a coaxial cable or other transmission train, and also the location in close proximity to antennas of different construction which influence the distribution of electromagnetic field in space. In this case, the antenna is in good agreement with the coaxial cable is 75-Ohm characteristic impedance without other adaptation This antenna is made by "com666" user.

The dimensions in yellow are for the 2300 MHz frequency...

,,, something like that, you can never say(3.5 x 3.5 = 12 (dbi)).. !!!!

Petra-9 MIMO 4x4 Unibox-2 is a 3G/4G antenna combined with a spacious sealed box (Unibox-2/Unibox-2L) in which you can place an LTE modem with support for MIMO 4x4 technology or two modems with support for MIMO 2x2 technology. The antenna is equipped with reliable connectors-SMA-male (50 ohms). Antenna adapters for connecting LTE modems are not included. The modem communicates with an indoor PC or router via a USB extension cable (USB 2.0). If the router is installed inside the box, the antenna can be equipped with a sealed PG-7 or RJ-45 pin (instead of a USB extension cable) Electrical characteristics of the PETRA-9 MIMO 4x4 UniBox-2 antenna Operating frequency range, MHz 1700÷2700 Gain factor, dBi 8,5÷10 Bottom width in the H-plane, deg 59÷82 Bottom width in the E-plane, deg 35÷57 Side lobe level, max -7 dB Decoupling between ports in the operating range, not less than 25 dB Input impedance, Ohms 50 SWR in the operating frequency range at the inputs, max. 1,5 Permissible power, W 10 Slope of polarization of received / emitted waves -45°/+45°(X-pol) Mechanical characteristics Weight of antenna, mount, box, extension cable g 1900 Bracing mast diameter 20-52 mm Operating temperature range -60°C to +80°C Overall dimensions without mounting, m 0, 24x0, 24x0, 1 Permissible wind speed, m / sec 25 Connectors 4 x SMA-male Material of the protective cover -Polycarbonate+ABS Antenna Material -Galvanized steel, brass Mounting material steel / Polycarbonate+ABS

,,,but anyway, I don't think that's the reality.... omni800-2600.cst
