<p>A telecommunication system uses a satellite antenna showing on the horizontal plane, a sufficiently narrow radiation lobe to discriminate two adjacent satellites and showing on the vertical plane, a sufficiently narrow vertical lobe to ensure an adequate gain, but sufficiently ample to enable the reception of a certain number of satellites in adjacent orbital positions, by land stations distributed over a certain meridian arc without the necessity for antenna elevation angle variations.</p> |
