We've shared tons of ways to boost your home Wi-Fi, but if you need something a bit more powerful, this DIY antenna can stretch your wireless network much further. Simply use this sardine cane box from which the cover is used for patch antenna... This box is ideal for the construction of antennas in the 5 GHz band and beyond...

Antenna BDM-2 is designed for outdoor use, although often applied in residential/non-residential premises. Experts recommend the use of antenna BDM-2, as a client equipment in all cases, build wireless networks of small and medium-range. The original of the antenna is with a 64mm diameter cylindrical vibrator

Your connector is not good, change it.,,,same with the router connection....!!!!

,,,pay attention to the connections to both the antenna and the router...!!! ,,,what kind of connector did you use here...???

Radiation patterns and gain measurements on 1.0, 1.5, and 2.0 lambda backfire Yagi antennas are given. The backfire antenna was tested for two dipole feed locations, and variations in the diameters of the two planar reflectors forming the backfire cavity. The optimum dimensions of the three test antennas are tabulated. The frequency bandwidth of the backfire antenna is limited to several percent due to impedance matching. The backfire antenna should find application in broadside arrays where conventional endfire antennas are presently used. 19680012807.pdf

These printed circuit board (PCB) antennas are perfect for high performance optimized antennas in a small package. These antennas are great for expanding your wireless network and improving your broadcasting or receiving stations.

,,,mitiche...please tell me how you posted the images above...!!!???

Waveguide slot antennas are a type of microwave antenna that use a hollow metal tube, called a waveguide, to transmit and receive electromagnetic waves. They have slots cut along the length of the waveguide, which act as radiating elements. Waveguide slot antennas have some advantages over other types of antennas, such as high efficiency, low loss, and wide bandwidth. Single Sided 8 Slots Waweguide...41x20x360mm....

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.

,,,length=multiples of 58.45 mm...!!!

,,,preferably RG-316...

,,,hi buddy...!!! The isolation between the two ports in this case is not very good....

,,,much like an omni-batwing antenna would behave... ,,,,but be aware that the sizes are different...!!!!

(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.

By the way, the reception of both " circular "polarization and" linear " can be conducted on ONE converter..... How....???? I'll tell you about it ..... in the meantime, take a close look at the "inside" of the circular converter. You can see the DIELECTRIC PLATE there, at a 45 degree angle...???? That's the key...,,,,, that is, capable of receiving both linearly polarized signals and circularly polarized signals..... ,,,and the dimension are...

Antenna-Bank (bandanna, banctenn, eng. cantenna) — name directional antennas-waveguide, made at home from tin cans. Typically used to extend the range of wireless devices. This cantenna, presents some changes as it would be 1) plate vibrator 2) adding a directing element 3) attaching a cone to the cylinder You can also use the simple vibrator....

,,,something like that...)))
