Abstract

An antenna stand for holding a flexible or non-flexible planar antenna includes a base and support frame. The support frame includes two spaced apart legs and a horizontal cross member interposed therebetween. At least two lower antenna supports are provided on the support frame on which the bottom edge of the planar antenna may rest. An optional extendable antenna holding arm includes an upper antenna clip that engages the top edge of the planar antenna. The extendable antenna holding arm support is adjustably mounted to the support frame so that the distance between the lower antenna supports and the upper antenna clip can be varied to accommodate planar antennas of varying dimensions. The support frame may be arcuately shaped transversely to impart a slight lateral bend to a flexible planar antenna mounted on the stand. This helps to maintain the flexible planar antenna in an upright position on the stand.
