HIGH QUALITY AND DURABLE Unity Gain Omnidirectional 6 Inches long antenna with 60 inches premium coaxial cable and male SMA connector.
APPLICATIONS 433MHz is a commonly used frequency band for all types of equipment that require little power, such as garage door openers, headphones, baby monitors and remote controls.
OMNIDIRECTIONAL Wireless transmitting or receiving antenna that sends or receives radio frequency (RF) and electromagnetic fields as well in all horizontal directions in a flat, two-dimensional (2D) geometric plane. Omnidirectional antennas are used in most consumer RF wireless devices, including cellular telephone handsets and wireless routers.
MAGNETIC BASE Designed with a magnetic base. The antenna can be placed on any iron surface horizontally or vertically. However, the vertical position is recommended for better signal.
SMA CONNECTOR AND 50 OHMS IMPEDANCE 60 inch coaxial cable with male SMA connector for easy connection, so no extension is needed.

-10dBm LO Power Consumption: Provides +24dBm third order intercept point, can achieve -10dBm LO power consumption, without high power LO drivers, there are no corresponding shielding and isolation problems, can improve system performance and reduce costs.
10.3dB SSB Noise Figure at 70MHz: With the output amplifier and optimal source impedance of this mixer module, the SSB noise figure is 10.3dB at 70MHz. There is no insertion loss, no external duplexer, and no passive termination.
Single Power Supply: The mixer module is designed to be powered by a single power supply, and the RF, IF and LO ports have DC isolation capacitors for easy use.
Wide Application: Suitable for applications such as RF‑IF down conversion in HF and VHF receivers, second mixer in base stations, DC baseband conversion, quadrature modulation and demodulation, and Doppler shift detection in imaging.
Low Distortion and Wide Dynamic Range: AD831 is a low distortion, wide dynamic range, single chip mixer, very practical.

The ESP-12F module combines the ESP8266 microcontroller with 4MB of flash and a PCB antenna, with 16-bit Lite mode, clocked at Supports 80 MHz and 160 MHz, supports RTOS, and integrates Wi-Fi MAC/BB/RF/PA/LNA..
The ESP-12F WiFi module supports the standard IEEE802.11 b/g/n protocol, a complete TCP/IP protocol stack. Users can use this module to add networking capabilities to existing devices or to build separate network controllers..
The default firmware can add WIFI capability to another microcontroller, but it really shines when loaded with MicroPython, or NodeMCU..
The ESP-12F is an improved version of the 12E, improve the peripheral circuit, the four laminates plate process, enhanced impedance matching, signal output is better, It is pin compatible with enhanced stability and a better antenna..
Not recommended for users who are new to the ESP8266. New users should instead look at development boards with integrated USB..
