Applications: The USB GPS antenna is a awesome choice for travelers, It works all over the world. Download the map of country your are traveling, it can quickly and accurately locate in exactly where you are without any pay, even in weak signal areas such as canyons, forest, in a vehicle and on the boat.It can widely used in vehicle monitoring, bus reporting stations, vehicle navigation, ship navigation, notebook navigation etc. | Interface: USB 2.0 ; Cable length: 190cm; Data baud rate: 9600 (default) (optional: 4800, 19200, 38400, 57600, 115200, etc.); Data refresh rate: 1Hz-10Hz refresh rate (can be set to output data 1-10 times per second); Built-in Flash, freely configure product baud rate, output statement, output rate, second pulse and other parameters; NMEA-0183 protocol output. | Note: It is a magntized antenna, when you use it in outdoor, If you want to get better GPS signal, please let GPS module face to sky. While you want to use it in indoor, please install GPS signal amplifier in your room. | Package included:1 x GPS Antenna

Wireless Transmitter Modules: It allow your to wirelessly communicate with radio frequency (RF) controlled devices that operate in the same frequency (433Mhz in this case). | Easy to Use: The antenna has a great influence on the receiving effect of the module,it is better to connect the antenna with 1/4 wavelength. Generally, 50 ohm single-core conductor is used. The antenna length of 433M is about 17cm.(Note:No antenna, please bring your own antenna.) Nice range (using antenna on both), you can send strings (text) from one point to another. If you want to automate your house without pulling cables then this device will help you well. | Note: The VCC voltage should be consistent with the working voltage of the module, and the power filter should be done well; The position of the antenna should be as straight as possible, away from the shield, high voltage and interference source.When used,the receiving frequency, decoding mode and oscillating resistance should match the transmitting. | Applications: The transmitter and receiver modules for increasing the communication distance. And the frequency is 433MHz.It is widely used in remote control systems, such as remote control switch/curtain/sockets/LED/audio/door/rolling gate/door opener, shutter and other door control systems, alarm host, alarm, remote control motorcycle, remote control controlled electric vehicle, remote control MP3, receiving module, automobile anti-theft products, home anti-theft products, electric doors,etc. | Package included: 5 x 433MHz Wireless Transmitter Module+5 x 433MHz Wireless Receiver Module
