Abstract: A personnel platform assembly and antenna support assembly for wireless communication transmitting and receiving devices such as antennas used in at least cellular telephone networks. The support assembly includes a support frame connectable upon an aerial tower which is adapted for supporting wireless communication transmitting and receiving devices thereupon. A connecting assembly is provided for fixing the support assembly at an above-ground elevation upon the aerial tower and a guide rail is suspended at a distance about the connecting assembly or central column of the tower. The guide rail is adapted for accepting a coupling to the wireless communication transmitting or receiving device and the coupling is continuously positionable along a length of the guide rail for accommodating variable positioning of the wireless communication transmitting or receiving device about the aerial tower.
