Protection Radius

Physical Spacing guidelines:

We coordinate three levels of protection based on the HAAT, and Power Level of your Repeater:

  • Level 1 – 45 mile protection radius for repeaters that have a HAAT below 150 feet, and an ERP of 50 watts or less.
  • Level 2 – 55 mile protection radius for repeaters that have a HAAT above 150 feet and below 450 feet, and an ERP between 50 and 200 watts. 
  • Level 3 – 70 mile protection radius for repeaters that have a HAAT above 450 feet, and an ERP above 200 watts. 

All repeaters that don’t have their ERP, antenna height and ground elevation on file will be coordinated at Level 1. If you believe your machine may be miscategorized, please contact the coordinator ASAP so that we may provide the appropriate level of protection.
