A feed legs assembly 120 connects a horn 180 and mount assembly 160 to a back frame 60 in an antenna assembly. The feed legs assembly 120 includes a main feed leg 122, a right side feed leg 140, and a left side feed leg 142. The main feed leg includes an amp frame 124, a feed strut 126, a quick release latch 128, an amplifier 132, a mating wave guide fitting 204, a flexible wave guide 137, wave guide end fitting 208, and a horn mount attachment 138. The amp frame 124 provides a protective structure around the amplifier 132, and wave guide end fitting 204, as well as lowering the overall profile and center of balance of the main feed leg 122. The wave guide end fitting of the flexible wave guide attaches to the mating wave guide fitting of the amplifier and carries the transmission signal to the horn. The side feed legs connect to the main feed leg 122 to the back frame. The side feed legs attach to the main feed leg 122 and back frame through Hein joints 148, 150, 156, and 158 and act as long turnbuckles. By rotating the entire side feed legs along the side feed leg longitudinal axes, the effective length of the side feed legs is adjusted, thereby raising the main feed leg (and attached horn and mount assembly) upwards and inwards towards a dish assembly 100 or downward and away from a dish assembly. Lockdown nuts 152, 154, 157, and 159 can be tightened to secure the side feed legs into position and prevent undesired movement of the turnbuckles.
