Tower Construction Considerations

When the use of AirLink T1/E1 systems requires construction of a tower, the

following requirements must be considered:

Local and provincial zoning and tower construction regulations:

These requirements generally mandate that permits be obtained before any

tower construction begins. Check with local zoning and state aviation

authorities for more information. Local requirements as to flight path

obstructions and the installation of proper markings and lighting need to be

evaluated and, if necessary, the proper local or national regulatory authorities

need to be informed. For details, contact Transport Canada, Microwave

Division.
