Being a portable operator and having used polarisation rotation (the 
advantage of having the antenna in one's hand), I agree that the 
ability to compensate for polarisation shifts, whether by hand 
rotating a LP antenna, using CP antennas or switching between two 
orthogonal LP antennas is a huge advantage for working LEOs.

Agreed.
