“Space communication has forced the use of Circular polarization. The fundamental advantage of circular polarization is that all reflections change the direction of polarization, precluding the usual addition or subtraction of main and reflected signals. Therefore there is far less fading and flutter when circular polarization is used at each end of the link.
The use of circular polarization at one end only gives a loss of about -3dB. In order to achieve the full advantages of circular polarization it is necessary for all stations to use it. The table below shows the relationship between Horizontal, Vertical, RHCP (Right Hand Circular Polarization) & LHCP (Left Hand Circular Polarization) and Loss in dB. RHCP is also known as CW (ClockWise) Polarization and LHCP as CCW (Counter ClockWise) Polarization.
Left Hand Circular Polarization
(LHCP)
Right Hand Circular Polarization
