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.

The present invention discloses an inner module container provided for containing active circuit elements for processing and transmitting cable television signals receivable from and transmissible through pins of coaxial cables. The inner module container includes direct access openings for receiving coaxial cable pins for securely connecting to the active circuit elements whereby the pins of the coaxial cables are connected to the active circuit elements without requiring a separate connector outside of the inner module container. In a preferred embodiment, the active circuit elements further include mechanisms for locking coaxial cable pins for directly and securely locking to the coaxial cable pins. In a specific embodiment, each of the mechanisms for locking coaxial cable pins includes a threaded screw attached to an upper plate and a lower plate for perpendicular screwing and horizontal locking, wherein the threaded screw is for perpendicularly tightening or loosening and horizontally rotating the lower plate to a locking or unlocking stop position and for perpendicularly tightening or loosening the locking plate from the coaxial cable pins for directly and securely locking and to conveniently unlock the active circuit elements from the coaxial cable pins.
