← ScienceWhich risk increases when a directional antenna misidentifies signal polarization?
A)Reduced signal strength at receiver✓
B)Increased antenna mechanical stress
C)Overheated transmitter amplifier
D)Elevated atmospheric radio interference
💡 Explanation
Signal polarization mismatch causes power loss because electromagnetic wave propagation requires alignment of electric field; therefore, signal strength decreases, rather than mechanical or thermal stress, which would occur by very different failure mechanisms.
