Spring Machine Coil Spring Copper CB 315mhz Antenna For Auto Parts Mobile Radios
A torsion spring is a spring that works by torsion or twisting; that is, a flexible elastic object that stores mechanical energy when it is twisted. When it is twisted, it exerts a force (actually torque) in the opposite direction, proportional to the amount (angle) it is twisted.
Electrical Characteristics:
1, Selection Skills Of Spring Antenna
Spring antenna can be divided into nickel plated, gold plated and copper spring antenna according to material. According to frequency, 315/490/868/915mhz spring antenna is common. Selection skills: when selecting spring antenna, it can be seen that its size, length, gain, impedance, material, frequency, standing wave ratio and other parameters meet the requirements according to the actual project requirements.
2, Selection Skills Of Rod Antenna
Rod antenna can be divided into straight rod antenna, elbow rod antenna and folded rod antenna according to the connection mode of antenna head; According to material classification: Gold Plated, nickel plated rod antenna. Selection skills: the rod antenna with corresponding frequency can be selected according to the module frequency used in the project, and the length of the rod antenna, the connection mode of antenna head, material, gain, impedance, standing wave ratio, etc. shall be noted.
3, Selection Skills Of Suction Cup Antenna
According to the frequency, it can be divided into 315/433/490/868/915mhz suction cup antenna and 2.4G small suction cup antenna. Selection skills: if the power of the module is more than 2W, it is recommended to select the suction cup antenna, and whether the parameters are waterproof through the project, considering the cable length, input impedance, standing wave ratio, gain, suction cup size and other parameters.
