The most common failure is moisture ingress, causing oxidation of the copper center conductor and increasing attenuation. This accounts for over 50% of failures. Prevent this by using waterproof connectors (e.g., IP67 rated) and sealing all outdoor connections with self-amalgamating tape to maintain a stable impedance.

Maintaining a low SWR (ideally below 1.5:1) is critical because high reflected power, from a mismatch, can overheat and damage transmitter components. A 3:1 SWR reflects 25% of your power, drastically reducing radiated signal strength and efficiency. Use an antenna analyzer to check SWR before transmission. What is SWR? A low SWR, say ​​1.5:1 or
