Abstract :
The best position for a feed for a paraboloid with an offset pattern is determined by deriving the exact form of the phase front in the receiving mode and approximating to a circle. Formulae are derived for obtaining the position of the centre of this circle and the extension to correcting lenses or subreflectors is indicated.
