Have a router with built in modem Huawei B683. Used in the country, the range is 2400 there clean. All anything, but Wi-fi gives it worse than a smartphone, the plot is not even enough, although installed in the wooden deck solder the pigtails and screw conventional pipettes from any router.Track is better to cut, as this connector is not found, and if found, it will break with the first poke. In extreme cases, all easy to restore in place

Two long arms are connected in the shape of V to make a V-antenna. The two long arms are excited with 180˚ out of phase. As the length of these arms increases, the gain and directivity also increases. The following figure shows a V-antenna with the transmission line impedance z=200 Ohm and the lengh of the arm 0,8*lambda, making an angle Φm with the axis, which is called as apex angle.material-FR4 #1.5mm. The main advantage of a V-shaped antenna is its relatively small vertical radiation angle, which is especially important for establishing long-distance communications.

Wireless access point MikroTik SXT LTE does not work in the 802.11 standard, and is equipped with LTE-modem with a directional antenna dual channel to work in LTE networks of mobile operators at speeds of up to 100Mbit. Maximum download speed up to 100 Mbps, and the return of up to 50 Mbps. SXT supports the most popular LTE band FDD - LTE 3 (1800 MHz) and 7 (2600 MHz). Has mini-SIM slot support 2G/4G network. The dimensions of the antenna

The modem supports operation in the following frequency ranges:: LTE FDD: 2100(1)/1900(2)/1800(3)/850(5)/2600(7)/900(8)/700(12)/700(17)/800(20)/1900(25)/850(26) MHz LTE TDD: 2600(38)/1900(39)/2300(40)/2500(41n) MHz 3G: 2100(1)/1900(2)/850(5)/900(8) 2G: 2(1900)/3(1800)/5(850)/8(900)

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...

On August 4, 1945, Soviet school children gave a carving of the Great Seal of the United States to U.S. Ambassador Averell Harriman. It hung in the ambassador's Moscow residential office until 1952 when the State Department discovered that it was 'bugged.' The microphone hidden inside was passive and only activated when the Soviets wanted it to be. They shot radio waves from a van parked outside into the ambassador's office and could then detect the changes of the microphone's diaphragm inside the resonant cavity. When Soviets turned off the radio waves it was virtually impossible to detect the hidden 'bug.' The Soviets were able to eavesdrop on the U.S. ambassador's conversations for six years. The replica on display in the Museum was molded from the original after it came to NSA for testing. The exhibit can be opened to reveal a copy of the microphone and the resonant cavity inside. https://counterespionage.com/great-seal-bug-part-1/ https://www.cryptomuseum.com/covert/bugs/thing/

Hello! After reading about Gray-Hoverman style antennas and how to do antenna, I will show you a new design plans, and assembly details available at "The Jeffrika7b Antenna" The Jeffrika7b is designed for a bi-directional, horizontally polarized reception patern over the two ATSC bands, VHF 7-13 (174-216 MHz) and UHF 14-36 (470-608 MHz), with an impedance of around 300 Ohms.

,,,this it"s the best... ,,,the MIMO variant will also appear later...!!!

,,,another McNeil achievement...

TP-Link CPE210/220 is a 2.4Ghz outdoor access point similar to Ubiquiti NanoStations. There is also a 5GHz Version of this AP, the TP-Link CPE510/520. The device has a built-in 12dBi 2x2 dual-polarized directional MIMO antenna with a beamwidth of 65° (H-Plane) and 35° (E-Plane)

A new small, low-profile and light-weight helical antenna element was designed for 2,1-2,4GHz-band communications. The novelty of the antenna is that its input impedance matching has been improved by adjusting the copper strip matching stub, while its circular polarization performance has been enhanced by changing the parasitic radiation patch loaded in the front of the antenna.

One of the very common types of antennas are loop antennas "triple square". And this applies not only to television, but to various types of wireless communication — Wi-Fi, 3G etc. Of course, frequency UHF 470 — 862 MHz are lower than Wi-Fi 2.4 GHz, but it is also worth considering. Central plastic stand is a holder for the active vibrator contains a passive antenna and the matching Board: in the form of equivalent half-wave cable loops on single sided PCB: The plastic center column with cable and the Central frame — the active vibrator (square side — 126mm): Rear frame reflector (side of the square — 154 mm) with bottom plastic spacer: Front frame — Director (the side of the square — 108 mm) with plastic spacer: Distance between the rear frame and the Central — 78 mm, and between Central and front — 58 mm. All part of used stainless steel wire diameter 4 mm.
