,,,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"

The antenna is used to connect to a repeater (amplifier) and is designed to amplify the GSM, 3G, LTE signal in offices, residential buildings and industrial premises, allowing you to get a stable stable signal for cell phones. The antenna has a wall mount that makes it easy to install and secure to the wall. Specifications: Frequency 791-821 MHz/ 832-862 MHz/ 1710-1785 MHz/ 1805-1880 MHz/ 2500-2570 MHz/ 2620-2690 MHz Type omnidirectional N - female connector Material plastic Gain up to 5 dBi Power up to 50W Cable length 20cm Operating temperature -40C: +60C Size17*10cm Wave resistance 50 ohms

,,,this is not a biquad antenna...!!!

,,,I have redone the dimensions (in green) for the 2.442 GHz frequency....!!!

2x2 antenna panel that shows a circular polarization and operates in 3G frequency band...

Maybe this will help you...

Is this type of antenna also REMO brand...???

The device is designed to provide stable access to the Internet via the USB - radio modems in the areas of uncertain reception of a signal of networks 3G (HSDPA/HSUPA/WCDMA2100) and 4G (LTE2600) of any operator. Range of working frequencies, MHz 1700...2700 Gain, dBi 12,5...15 Cable length, m 5 Overall dimensions of the antenna, mm 240x240x20 Overall connectors remover, mm 150х65х35 Set weight, not more, kg 1,5

Here are some quick notes about the parabolic type dish antennas you might find. The actual antenna is a normal half wave dipole with an integrated balun and is located inside the sealed plastic cover. The mesh screen is the reflector which concentrates the RF energy onto the antenna. That is how dish antennas increase the received or transmitted power level. Also, wireless cable service providers frown upon giving away their used dishes as they think you're going to steal cable service.

,,,model... 917 x 720 welded iron bars (Pacific Grid) 917mmx720mm and 150mm deep f/d = 0.38 grid parabola.cst

,,,,for 50 Ohm... ,,,,next 75 Ohm ,,,technical details... ,,,to change the impedance the power pin diameter(d0) must be changed...!!! The SMA plug remains the same, 50 Ohm impedance, only the coaxial cable is 75 Ohm.

,,, type of antenna,not very easy to produce , but with good results in circular polarization. Between the patch and irradiated put plate of polystyrene or polyurethane...

,,,this must be it...!!!

Double Patch Regular Polyhedron The rectangle 94*68 mm, the sides of the cutting plane 28 and 16 mm rack Diameter 6 mm. each patch has an input impedance of 100 Ohms, between 0.5 *Lambda of the connecting line. Obtained by parallel connection of 50 Ohms. And cool chart SWR the broadband is a patch in the form of an pseudo- ellipse with eccentricity 0.8, 2 Patches of narrow-band, but with the increase of the gap band of operating frequencies increases at 0.1 Lambda reaches 10/11 %. When band gaps, increases the ability of multi-mode excitation. With the increase of the gap increases and the value of the input impedance. Based on this information, can built a patch with a gap from the reflector is 15 mm. The line length is 0.5 L, so its width is not critical. In this project its width is about 2 mm d = 1 mm The gap( between the surfaces) 15 mm width to reflector Conn. line 13 mm. the distance between the two coherent emitters choose, usually based on two criteria. Or the maximum gain, then it's 1 lambda or a little more. Or at a minimum side lobes, then it is less than lambda, about 0.7/0.8.

A cantenna ( blending the words can and antenna) is a homemade directional waveguide antenna, made out of an open-ended metal can. Cantennas are typically used to increase the range of (or discover) wi-fi networks. Although some designs are based on a can, this tube is too narrow to increase the 2.4 GHz signal by a useful amount, although at 5 GHz it would be about the right size. However, a cantenna can be made from various cans or tubes of an appropriate diameter. Some designs include a pole mount to elevate the cantenna.
