Notes on mounting brackets Example bracket configuration
  • The antenna comes with the bottom mount studs (marked as 1 ) factory-installed.
  • JMA cylinder brackets are compatible with bottom mount via universal cantenna mount sleeve (marked as 2 ) (SC-BKT-SLA), sold separately with JMA cylinder mounting systems.
  • To mitigate potential risk of PIM issues, the recommended torque values need to be applied.
