Abstract: An apparatus for mounting an antenna at the upper end of a mast. The antenna has a first electrical connector extending downward from its lower end. The mast has a second electrical connector extending upward from its upper end and is interengageable with the first connector. The apparatus comprises a head moveably adjustable on the upper end of the mast. The head has a skirt surrounding the mast and an upper surface. The upper surface has an opening therein dimensioned for passage of the connectors. The head is movable downwardly on the upper end of the mast to a lowered retracted position and movable upwardly on the upper end of the mast to a raised extended position. When the head is in its retracted position the second connector extends up through the opening above the upper surface for connection of the connectors.
