433 Mhz 3dbi magnetic mount
In stock
An antenna is a device to transmit and receive electromagnetic waves. Electromagnetic waves are often referred to as radio waves. Most antennas are resonant devices, which operate efficiently over a relatively narrow frequency band. Antennas can be designed to transmit and receive radio waves in all horizontal directions equally (omnidirectional antennas), or preferentially in a particular direction. Here you can get an antenna for UBlox NEO GPS model, Antenna Base Set and many more GPS modules.
