Only by selecting the correct antenna and using it correctly can we ensure good antenna performance.

The quality control of spring antennas is very important. As spring antennas are produced using spring machines, the performance of each batch of antennas may not be completely consistent. In this case, quality control is particularly important. Professional antenna companies will conduct targeted quality control testing to ensure the consistency of antenna performance, while non professional companies often do not have such control.
The welding of the spring antenna is also a crucial step, because the characteristics of the antenna determine that even if the antenna is welded in the same position, if the welding direction and technique are not consistent, it will lead to differences in antenna performance. How big is the specific difference? Let's still conduct an experiment. Weld the same antenna to the same position on the test board, but intentionally weld the antenna in a different direction.
The same antenna is soldered to the same position on the same test circuit board, with only a difference in soldering direction. However, in this case, there is also a significant difference in the resonant frequency of the antenna during testing. It can be seen that inconsistent soldering techniques can also cause antenna performance issues when using spring antennas.
