Abstract
A radiotelephone, used in a satellite radiotelephone system, has an antenna (12) with a hemispherical gain pattern (14). Since a satellite (18) can be anywhere in the sky the antenna gain pattern (14) needs to be aligned with the hemisphere above the user. This is accomplished with an antenna positioning apparatus, comprising the antenna (12) having a wedge shaped mating surface (42) affixed to an attaching surface (36) by a pin (38) and socket (44). The attaching surface (36) slopes downward from a plane (24) defined by a front face (26) of the radiotelephone (10). The combination of the wedge shaped mating surface (42) and the downward sloping attaching surface (36) positions the antenna (12) at an angle .phi. from the plane (24) when the antenna is in the active position. As a result the antenna (12) is vertically oriented when held by the user during normal use.
