Abstract

An antenna orientation device which includes a base, an antenna structure with a first bearing surface, and a support for positioning the structure in relation to the base. The support includes a body coupled to the base and having a stem. The support also includes a resilient non-metallic bearing member carried on the stem which has a second bearing surface. The support also includes a fastener connected to the body for clamping the first and second bearing surfaces in rotary bearing relation. The bearing member is elastically deformed to provide retaining force sufficient to hold the structure against earth'"'"'s gravitational pull in any one of a range of rotational positions about a substantially non-vertical axis. Each position within the range is selectable by rotating the structure by hand. This support can provide a rotational range of at least 45 degrees. The fastener may be configured as an adjustable screw to provide a way to vary retaining force.
