← ScienceWhich consequence results when rapid atmospheric icing decreases antenna capacitance?
A)Frequency resonance point shifts negatively
B)Impedance matching efficacy degrades quickly✓
C)Transmitter power handling unexpectedly increases
D)Antenna SWR withstand increases greatly
💡 Explanation
Icing accumulation changes antenna's overall permittivity; this dielectric change affects its capacitance through capacitive drift. Impedance mis-match worsens because the **reactive impedance** changes, therefore more signal reflects power rather than radiating into the atmosphere, rather than a shift in frequency alone.
