One end attaches to a dowel stud on the side of the dish and is secured by a wing nut. The other end attaches to the wing nutted bolt on the radio support arm. - Page 13 3.0 Directions for Set up and Use: The antenna unit is relatively easy to set up and use. 1. Roll the case to the desired location. The free rolling swivel casters make it easy to move the case. The casters are robust enough to handle routine curbs, cracks, and bumps. It should be noted, however, that since the transit case is tall and slender, it could tip if it encounters an incline or surface discontinuity transverse to the longest case axis.
