In very rare cases a mismatched aerial may not be detected. This is because depending upon
the length of the coaxial cable the impedance presented (varying with frequency and power
setting) may appear to be suitably matched within the limits set by the command used above.
This condition is close to impossible to detect in some cases using any method of detection (other
than using a remote receiver to monitor signal strength).
To overcome this if a problem is ever encountered you can either:
• Change the length on the aerial coax slightly or
• Change to a different aerial or
• Tighten the limits of the _MISMATCH_CONFIG command.
