  • Page 11 8. Locate two V-Saddle blocks, two stainless steel V-Bolts, four stainless steel 3/8" flat washers, four stainless steel 3/8" split lock washers and four stainless steel 3/8-16 hex head nuts. Loosely assemble (one or two threads beyond the end of the hex nuts) the two V-Bolts to the stainless steel Pivot Base Winch Mount as shown below.
  • Page 12 10. Move the four V-Bolts out as far as they will go (these were put on loosely in earlier steps). Slide the entire assembly onto your mounting pipe. You want approximately 1 inch clearance from the top of your mounting pipe to the bottom side of the winch mounting plate. Position the base fixture in the position you pre-selected for the pivoting direction.
  • Page 13 11. Using your 3" OD antenna bottom element section. Loosen the previously installed U-Bolts. Insert your 3” OD antenna bottom element section into the antenna base section through the upper and lower U-Bolts. The bottom of your 3" OD element tube should be even with the bottom of the insulated channel as shown below.
