V-dipole antenna construction set

This is my go at building a V-dipole antenna (weather sat image reception)

The set includes :

• Antenna base (120 deg.) it uses :
  • 2x 16mm choc blocks (CHS TBS 16mm2 / nf 1751AP)
  • 2x alu rods (diameter 4mm - length 53,4mm)
  • 1x SO239 / 83-1R UHF connector
  • 4x M3 bolts and nuts to mount the SO239 to the base
  • 2x M3 bolts and nuts to attach the base to the support
  • 2x 3mm screws to fix the cover to the base
  • silicone as needed
  
  
• Cap or cover :
  • small version 1
  • larger version 2 that covers the connectors
  
  
• Support/mast clamp for standard 50mm, 40mm and 32mm PVC tube (needs 4 M6 bolts, washers and nuts)

The construction of the antenna follows the well-known 'Adam-9A4QV manual' (see http://rfelektronik.se/manuals/Datasheets/DIY%20137MHz%20WX-sat%20V-dipole%20antenna.pdf)

In a way the set presented here is easier to construct :

• No need to bend the alu rods, they go straight into the choc blocks
• You only need to solder 2 short wires between the SO239 and the 2 choc blocks
