# What is the polarization loss between RHCP transmitter, aircraft reflection, and reception by vertically polarized antenna?

A stationary transmitter transmits RHCP radio waves. These are reflected by aircraft as LHCP. A stationary receiver receives them using a vertically polarised Yagi-Uda antenna. Is the polarization loss at the receiver end $$-10\cdot\log_{10}(0.5)=+3.0$$ dB when only perfect reflection is considered?

• yes, a linear polarized antenna of any orientation will receive a left or a right circularly polarized signal with 3dB loss – hyportnex Jan 22 at 15:56
