[QUOTE="PaulR, post: 467786, member: 176256"] Circular polarisation can be imagined as a dipole aerial transmitter that rotates once for every cycle of frequency. Therefore there's at least sometime during the rotation when the receiving horizontal or vertical aerial will be in line. I think the loss in strength is 3dB but the gain is that, as long as the aerial is pointed in the right direction, then there will be a constant signal. [/QUOTE]
