A cross polarization occurs when -

40. A cross polarization occurs when -

1. Cross polarisation occurs when the receiving antenna is polarised in the opposite direction as the broadcast wave
2. Cross-polarisation occurs when the receiving antenna is polarised in the same direction as the broadcast wave
3. Cross polarisation occurs when the receiving antenna is polarised in a random direction as the broadcast wave
4. All of the above

Answer: A) Cross polarisation occurs when the receiving antenna is polarised in the opposite direction as the broadcast wave.

Explanation:

Cross polarisation occurs when the receiving antenna is polarised in the opposite direction as the broadcast wave, this situation often degrades the signal performance because of which communication is weaken.
