Abstract
A seal for preventing intrusion of moisture between a lowermost or first movable tube section of a power operated antenna mast and an insulator between the first tube section and the panel through which the mast projects, the seal including a substantially inelastic polymeric insulator mounted on the panel with a bore therethrough surrounding the first tube section, an inside surface on the insulator perpendicular to the bore intersecting the latter at a lip extending through 360.degree. around the first tube section, and a substantially inelastic polymeric sleeve on and movable with the first tube section having an annular frustoconical seal shoulder engageable on the lip in an extended position of the first tube section to define a moisture seal between the latter and the insulator.
