The invention provides a transmission and display device and an antenna. The transmission and display device comprises a supporting base, a transmission screw and a transmission nut. The supporting base is cylindrical, a transparent window stretching in the axial direction is formed in the cylinder wall of the supporting base, and scale marks corresponding to downward inclination angles of the antenna are formed at the position of the transparent window. The transmission screw penetrates into the supporting base and can rotate relative to the axial direction of the supporting base. The periphery of the transmission screw is sleeved with the transmission nut, the transmission nut can rotationally move relative to the axial direction of the transmission screw, a change-over rod is arranged at one end of the transmission nut, a pull rod connecting part is arranged at the end, away from the transmission nut, of the change-over rod, and the pull rod connecting part stretches in the axial direction of the supportin
