Antenna setup

  • Follow instructions from the antenna manual, being careful not to lose nuts and bolts!
  • Before attaching the choke (coil thing at the large end), check using voltmeter there is no electrical short between the 2 sides of the antenna.
  • Cable tie RF cable to the beam, making sure it remains aligned with the beam.
  • Do not tighten coax connectors too much, just finger tight.
