Sealed box for 3G / 4G modem with built-in wide-band MIMO antenna and integrated 10-meter USB cable. The device is completely ready for self-installation: inside the case you will find two CRC9 pigtails for connecting the antenna part to the modem, and the complete mount will allow you to easily install the PETRA-12 MIMO 2x2 BOX on a facade bracket, pole or remote mast. Nothing prevents the device from being used indoors as well!

Antennas are essential wherever wireless communication required. They are the indispensable link between the contained signal and the “ether”. CST provides a variety of tools for each stage of the antenna design flow to study and improve your design. Antennas are used in a vast variety of applications, and thus take come in a vast variety of form factors and radiation mechanisms. The range of simulation methods in CST MWS allows the engineer to choose the best technique for each application. The transient solver could be best for wideband or planar antennas, the frequency domain solver may be more suitable for electrically small antennas, while the integral equation solver can efficiently simulate electrically large or wire antennas. Antennas never operate in isolation, but are attached to a feed network. CST DESIGN STUDIO™ (CST DS) allows the hybrid co-simulation of the effect of an attached circuit on the antenna performance. Installation of an antenna in a device or on a platform makes its analysis even more complex. The System Assembly and Modelling framework in CST DS allows the user to set up coupled simulations which can combine different solvers automatically by making use of field sources. Finally, powerful automated post-processing allows you to extract every magnitude of interest for an antenna designer – nearfield plots, SAR, phase center, directivity or farfield gain for single antennas or arrays - and to process those data further for use in parameter sweeps or optimizations in order to improve the performance of your design.

Universal antenna Petra-9 MIMO 2x2 built-in professional sealed box. CRC9 connectors. F=1700-2700 MHz. GAIN=9dBi. Polarization X-pol. Standards: LTE-A, LTE1800, LTE2600, UMTS2100, WIFI. PETRA-9 MIMO 2x2 Box is the antenna combined with a large sealed box in which you can put any 3G/4G modem and even router. The antenna is provided with connectors - CRC-9. The connection of modem to PC or router located in the room is via a USB extension cable. A sealed box will protect the modem from adverse weather conditions!

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.

,,,one port is horizontally polarized and the other is vertically polarized...!!!

That's how it should be...

Is that what you want...??

,,,do you want something like this...???

,,,f/D=0.25...you can see the difference...!!!

,,,read this..https://www.antenna-theory.com/antennas/reflectors/dish3.php#:~:text=Aperture Taper Efficiency&text=This efficiency can be improved,the spillover efficiency%2C discussed next.

Antenna for digital TV is no different from antennas for analog TV. choose from a large Ku. Specify which channels are broadcasting UHF. the antenna should cover the range(500-800MHz). This is a realization of VodkaMan friend. Some improvements for this type af patch antenna UHF: Mounting studs M6 with nuts and washers. Line powering with ramps instead of fillets (I think smarter). Reflector rectangular 340mmx290mm, the distance between studs 120mm. Patch - 208mmx208mm truncated cylinder 214mm installed at a height of 65 mm (the gap). Director - 173.6 mm in diameter, at a height of 95.5 mm from the reflector (the gap). Material - galvanized 0.5 mm.

I tried to optimize your antenna for 2442 MHz .....

If we had to participate in field tests of a transceiving apparatus, part of which was various types of antennas, and as Omni-directional, they are independent from the design and the claimed gain in performance for range transmission and reception is insignificantly different from each other. A significant difference was their price. Of greater importance, as we understand it from practice, had such option antenna as it is efficiency, which directly connected with the working surface (the larger antenna size than she is better), but not with the stated gain. So simple homemade omnidirectional antenna is not what is not inferior to similar fancy designs. For beginners, we don't would advise to grasp for the production of Omni-directional antennas with a large gain such as collinear or the like. Without skills and lack measuring instruments to achieve from these structures excellent results not will. The antenna that we propose to assemble, has an important property. First of all, it is quite simple and broadband (bandwidth 200 MHz), this means that miss relative to the fundamental frequency of transmission and reception as a result of the inaccuracy construction will be difficult, which is an important factor in the case the lack of measuring devices. However, simple a homemade antenna will differ markedly from the purchase of the product may because a nested design energy of creativity yields results. The antenna is a quarter-wave vibrator with a counterweight

Pupe, try a Strella-11 omni antenna too....!!! I think we still need to work on this...

Also available for sale are the more powerful Stella-8 and Stella-11 antennas with a gain of 8 dBi and 11 dBi, respectively.

,,,that's what it would be like... reflector diameter=180 mm

,,,122 mm diameter.../// I don"t think so...!!! ///maybe 40,5mm iameter...!!!

,,,what is the diameter of the rings and plate...!!!
