This guide lists the Sinclair clamps available for most standard antenna installations. Each column identifies one or more clamps by the Sinclair number and indicates whether these are suitable for use with round support pipes or tower legs, 60 degree angles, 90 degree angles, or other mounting situations. For ease of reference, similar antennas are grouped together, as are similar  clamps. An extensive range of non-standard mounting hardware is also available  on a special order basis.  If you have any other requirements or need further  assistance, consult your Sinclair representative. Before ordering clamps or mounting hardware for your particular requirement,  consider whether a professional review of all relevant factors is necessary. The information contained in this document is provided for reference only: the customer is responsible for compliance with all applicable engineering and safety standards and regulations. Click here to download the Sinclair Clamp and Side Mount Selection Guide.
