Description: 433MHz 315Mhz Spring Helical Antenna for Wireless Module Helical Copper GSM/GPRS433MHz 315Mhz Spring Helical Antenna for Wireless Module Helical Copper GSM/GPRS Product Information: Antenna is a kind of transformer, which transforms the guided wave propagating on the transmission line into the electromagnetic wave propagating in the unbounded medium (usually free space), or performs the opposite transformation. A component used in radio equipment to transmit or receive electromagnetic waves. Engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, radio astronomy, etc., which use electromagnetic waves to transmit information, all rely on antennas to work. In addition, in the transmission of energy by electromagnetic waves, the energy radiation of non-signal also requires antennas. Generally, antennas are reversible, that is, the same antenna can be used as both a transmitting antenna and a receiving antenna. The basic characteristic parameters of the same antenna as transmission or reception are the same. This is the reciprocity theorem for antennas.Name: GSM spring antenna/L typeFrequency range (MHz): 824-960MHz+/1 710-1990MHzStanding wave ratio: ≤1.8Input Impedance: 50Gain: 2dBi-3dBiWire diameter (mm): 0.8MMSpring outer diameter: 5MMTotal length including welding part: 24MMInterface form: direct welding Anything else you need? - add more items to the shopping basket to qualify for combined flat rate postage.
