Caution
This information is provided for general guidance only. Installers must select components suitable for the specific installation conditions, taking into account the size and wind loading of the aerials and/or dishes to be supported, the degree of site exposure, the condition of the masonry and the required stand-off.
Attention is drawn to the CAI Code of Practice for installing receiving antennas and to BS EN 60728-11. For additional stability, where space allows, a double-fit option can be used for increased support.
