Multiband Antenna Gearmotor Assembly
Ball Bearing Assembly
In this photo the Delrin bearing housing with the 2 sealed ball bearings installed is awaiting final assembly.
This assembly once completed will be mounted in place on the all-thread Stainless Steel drive-rod just above the gearmotor, and fastened to the lower mast tube. This bearing assembly will relieve the radial load on the gearmotor, while at the same time protecting the gearmotor from the axial load of the coil assembly, as the coil is driven up & down within the mast assembly.
