Abstract

The present invention discloses an integrated single-body antenna-transceiver assembly for a multi-channel multi-point distribution system (MMDS) transceiver for bi-directional signal transmission and reception. The assembly comprises a dipole antenna-body comprising a surrounded plastic-molded exterior with interior metal dipole antenna extending vertically from a metal attachment-seat surrounding a signal feed pin connected to the dipole antenna. The assembly further comprises an MMDS transceiver having a transmitter printed circuit board (PCB) and a receiver PCB enclosed in a waterproof-metal housing having an antenna-attachment pad including a signal feed pin opening. The dipole antenna-body is securely attached to the waterproof-metal housing by attaching to the antenna-attachment pad sealed with an O-ring with the signal feed pin extended through the signal feed pin opening to contact the receiver PCB, the diplexer, and the transmitter PCB. In a preferred embodiment, metal housing for enclosing the transceiver further includes mounting means for securely mounting a reflector thereon. In another preferred embodiment, the metal housing for enclosing the transceiver further includes two types of mounting means corresponding with either horizontal or vertical signal polarization for several types of reflectors thereon.
