What Factors Affect Antenna Service Life?

The service life of an antenna is influenced by multiple factors:

1. Housing material of external antennas
This includes whether the plastic housing is UV-resistant and the mechanical hardness of the enclosure material.

2. Material of the internal antenna element
Common internal antennas made of nickel-plated copper offer good resistance to long-term salt spray corrosion. In contrast, antennas made of high-carbon steel may corrode rapidly, leading to performance degradation or complete failure.

3. Installation method of internal antennas
Internal antennas may be:

l Directly soldered onto the PCB

l Attached to the inner wall of the enclosure using adhesive backing

l Positioned using plastic heat staking

l Fixed inside the device with screws

Each mounting method has its own advantages and disadvantages.

4. Interface between the antenna and mounting base
If there is direct contact between metal parts, special attention must be paid to electrochemical reactions, which can cause galvanic corrosion, leading to loosening or rust at the connection point.

5. Vibration and shock resistance
For long-term operation in high-impact or high-vibration environments, factors such as material fatigue and fracture of connectors must be carefully considered.
