Maximum ERP

The Maximum ERP tool allows you to compute the maximum effective radiated power, in watts, to be used at a specific location, under FCC Rule 90.205 for Power and Antenna Height Limits.  If you don’t have your HAAT (height above average terrain, a key component used to determine ERP), you can provide your site antenna height and ground elevation.

An accurate location can only be determined if you are using a wireless network.
