Explanation
Overview Power handling is the maximum RF power an antenna or component can safely withstand without excessive heating, electrical breakdown, or permanent damage. Power handling depends on much more than transmitter output power alone. Factors Affecting Power Handling Operating frequency. Operating mode. Duty cycle. Component temperature. RF voltage. RF current. Ambient conditions. Digital Modes Digital operating modes often require significantly lower power because their high duty cycle produces much greater average heating than SSB voice operation. Mechanical Limitations Power handling is not determined solely by electrical characteristics. Mechanical construction, conductor size, connectors, capacitors, transformers, and inductors all contribute to the overall rating. Applied to Chameleon Products Every Chameleon product has published power ratings based on extensive engineering evaluation. Operators should always follow the published SSB, CW, and digital-mode power limits for safe operation. Related Articles Why Do Digital Modes Require Lower Power? What Is RF Voltage?

The exact result depends on the complete station: frequency, geometry, feed line, matching network, return-current path, environment, operating power, and the reference plane of any measurement. A low SWR establishes an impedance relationship at that point; it does not by itself prove efficiency, radiation pattern, compatibility, or safety.
What to Verify
- Use the newest official product guide or primary service documentation.
- Confirm the exact model, revision, components, configuration, and operating conditions.
- Begin tests at low power and change one variable at a time.
- Do not infer compatibility from connector or thread fit.
