A method of feeding out field power from a circularly polarized antenna (2), mounted on a conductive aircraft surface (1). All power is normally fed out in circular polarization to the receiver, irrespective of the elevation angle ( theta ) and the azimuth angle ( alpha ). For increasing the antenna amplification at elevation angles theta greater than or approximately equal to 60<o>, where substantially only the vertical polarization can be seen, it is proposed in accordance with the method that all power is fed out in linear polarization with the aid of a polarization switch (4). |
