CAI Benchmarking Scheme for Aerials

The Benefits of Aerial Benchmarking

The only way of ASSURING levels of PERFORMANCE for:

  • gain,
  • impedance match (return loss)
  • pattern (F/B, sidelobes, etc.) - cross-polar discrimination
  • rejection of pick-up on feeder

INDEPENDENTLY tested by an accredited test lab

  • no need to rely on manufacturers' claims alone

IMPULSE INTERFERENCE problems reduced by low feeder pick-up

  • yet performance data not generally available from manufacturers

COMPARE different manufacturers' offerings more easily

  • no more confusion over dBi / dBd, differing frequency ranges or voltage/log scales on polar plots etc.

Professional IMAGE of installer enhanced

Constant REVIEW of all products granted the 'mark'

An INCENTIVE for manufacturers to improve products

ONGOING development of standards

  • extensions planned to cover other types of aerial

STANDARD 1 aerial performance consistent with coverage planning assumptions

SUPPORTED both by industry and government bodies
