Waterproof + magnetic base: environmentally friendly ABS material, one-piece waterproof shell, which can effectively prevent the rain from damaging the antenna components. Hidden non-slip magnetic base design, strong and stable adsorption, where there is metal, can be firmly attached.
Versatile compatibility: for LTE routers, home phone WiFi hotspot router modems, cellular IoT gateways, wireless monitoring, robot arms, smart homes, robots and more. Compatible with all carriers.
Usage instructions: The router has the option to manually adjust the bands (usually bands 3 and 7 are faster, but have a lower signal strength, so this antenna solves the reception problem and allows you to surf the Internet at the highest speed). If your router is connected to a band that corresponds to the network frequency B1 or B20, the Internet speed is sometimes poor, but this is not due to the antenna.
Parameters & Packing List: Frequency range: 600-6000MHz; Antenna Gain: 15DBI; Direction: Omni-Directional; Polarization: Vertical; Impedance: 50 Ohm; VSWR: <1.5.Package List: 2 * SMA WiFi Antennas + 3M RG174 Cable; 2 * TS-9 Connectors
15DBI Omni Antenna: This full-band universal antenna can receive difficult LTE signals. It improves the received signal and speed (carrier dependent) to the original signal strength. It will bring you better performance and connection stability to maximize the speed in your home or office.

High performance: The AD9833 has a standard serial interface that allows the part to communicate directly with multiple microprocessors. The device uses an external serial clock to write the data or control information into the device.
Compact design: The output frequency and phase are programmable via software and allow easy tuning. No external components are required. The frequency registers are 28 bit wide: at a clock speed of 25 MHz, a resolution of 0.1 Hz can be achieved; with a clock speed of 1 MHz, the AD9833 can be tuned to a resolution of 0.004 Hz.
Applications: The AD9833WBRMZ-REEL model is available with controlled manufacturing to meet the quality and reliability requirements of automotive applications. Note that the specifications of this car model may differ from those of the commercial models. Therefore, designers should carefully read the "Specifications" section of this datasheet.
AD9833: The AD9833 is a programmable waveform generator with low power consumption that can produce sine, triangular and rectangular wave outputs. The generation of waveforms is required in various types of sensor, actuation, and time domain reflectometry (TDR) applications.
