Installation Instructions

How to Install Shakespeare 408-R Upper Antenna Bracket

You will need:

  • Drill
  • Drill bit for 1/4" screws
  • Screwdriver
  • Wrench or pliers


  • Loosen the wingnut on the top of the bracket and slide the retainer bar out of the way. Place the antenna in its mounting position in the U-shaped opening in the bracket. 
    • Note: For 1-1/8" and 1" antennas, put the appropriate reducing adapter in the opening. 
  • Rotate the retainer bar over the antenna to lock it in place. 
  • Using the bracket itself as a template, mark the position for its mounting holes. 
  • Drill 1/4" mounting holes, and install the bracket using stainless steel machine screws, washers, lockwashers, and nuts. (Hardware is sold seperately).
    • For mounting to some types of surfaces, you might need to substitute stainless steel woodscrews or other hardware.
  • Tighten the wing nut to secure the antenna in the bracket. The completed installation should attach the antenna firmly to the mounting surface, leaving no "play" between the antenna and the bracket.
