,,,you must not have any obstacles in front of the antenna...!!!!
-
,,,for what 100 meter distance,to create a wifi bridge= Direct visibility, Distance 2.5 km.
-
Here's the problem, you have to keep this in mind....!!!
-
,,,and an improved version with elliptical patches... ,,,with wings...
-
Yes, there are two versions of the cantena, a simple one and a combined one.
-
,,,it's also possible...with cantenna... ,,,with some disk plate as directors....
-
Yes, that's about it...still needs work...!11
-
Try this too ... 3.52-1ghz.cst
-
,,,see it...!!!
-
,,,you know how to work with cst-studio...???
-
,,,choose the tube with 6 mm diameter...!!!
-
,,,the material doesn't matter...the main thing is that it can be welded...!!! ,,,for your frequency range a smaller thickness is preferable...!! ,,,all the antenna elements are electrically connected...!!!
-
YES,,,the second port is at 120 degrees...!!!
-
,,,not 45 degrees,120 degrees...!!!

They don't really like Petra 9 I picked one out, I attach a photo report...

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

,,,this is for you...(Why isn't you forget to see about Messages(up) 3300-3800 MHz BESTER.cst
-
I will design you such an antenna for the desired frequency....!!!
-
I think I'll make you a good antenna for the desired frequency."
-
ChatGPT or DeepSeek will never be able to solve your problems in a real way...it's fake"
-
papagayor...see this ",,,such an antenna can be calculated for the 3300-3800 MHz band"
-
,,,this is not a biquad antenna...!!!
-
,,,I have redone the dimensions (in green) for the 2.442 GHz frequency....!!!
-
Maybe this will help you...
-
Is this type of antenna also REMO brand...???
