Abstract
A spring hanger system for supporting a UHF circular waveguide from a transmission tower and including a plurality of vertically spaced spring hangers, each adapted to engage an adjacent section in the vertical run of waveguide in the tower. Each hanger includes a glide ring fixed to the tower for restraining the waveguide from movement in any direction except vertical; a clamping ring spaced axially below the glide ring which is adapted to grip the outer periphery of the waveguide snugly without distorting same, whereby the waveguide is stiffened against deformation by lateral forces in the region of the glide ring; and a spring mechanism connecting the glide ring and the clamping ring with a substantially constant force which allows the waveguide to move in response to differential expansion with respect to the tower.
