An apparatus for holding an antenna on a mounting surface by use of suction cups or suction devices such that the antenna may be temporarily removed from the surface and subsequently restored or relocated to another mounting surface. The suction cups or suction devices are mechanically connected to an support arm capable of adjustment for permitting either vertical or horizontal modification of the holding arm thereby maintaining a constant mounting angle of the holding arm for surfaces having various mounting directions or planes. By maintaining a fixed vertical of the holding arm from various mounting points, the directional alignment of the antenna, such as for a dish-type antenna, can remain relatively consistent from one installation to the next.
