Abstract

A horn mount assembly 160 attaches a horn assembly 180 to a main feed leg 122 and provides adjustment on the Y-Z tilt axis and along the z-axis axis. The horn mount assembly includes a wave guide mount circular clamp 162, a flexible wave guide mount 163, a horn circular clamp 164, a feed strut attachment plate 166, a Y-Z tilt jack screw 170, and a Z-axis jack screw 172. The feed strut attachment plate attaches to the main feed leg, while the horn assembly is secured by the horn circular clamp. The flexible wave guide mount is secured by the wave guide mount circular clamp, and a flexible wave guide connects to the flexible wave guide mount. The z-axis jack screw allows the horn assembly to move along the horn transmission beam axis towards and away from the centerpoint of illumination 110 of a dish assembly 100. The Y-Z tilt jack screw allows the horn assembly to pivot in a vertical plane. A polarization drive assembly 190 is used to remotely adjust the polarity of the horn assembly via the horn mount assembly while the antenna system is actively transmitting a signal. The polarization drive assembly 190 includes a worm drive 192, a torque plate 193, a flex drive torque cable 194, an adjustment knob 196, and a cable disconnect 198. The worm drive connects to the horn mount assembly. The torque cable connects the adjustment knob to the worm drive. The torque cable allows an operator to stand behind the dish, and use the adjustment knob to manually adjust the polar orientation of the horn assembly while the antenna system is operating and microwaves are being generated. Furthermore, a laser alignment device 250 is utilized to facilitate aligning the horn mount assembly 160 with the dish assembly 100. The device 250 includes an alignment wave guide mount 252, an alignment horn end mount 254, and an elongated shaft 256.
