I want to know the answer to the following question:
What is one use that would require an antenna to receive signals in various ways at once?
All the background I'm provided with is that "In some applications where the receiving antenna must work in any position, as in mobile phones, the base station antennas use mixed polarization, such as linear polarization at an angle (with both vertical and horizontal components) or circular polarization.". Is that enough to answer the question?
Answer: yes
