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
