Planning context · not a SAS
See where federal Dynamic Protection Areas and Priority Access Licenses sit, then check a site: which Part 96 device class applies, how high an outdoor Category A antenna can go before it counts as Category B, and which DPA neighborhoods include the point.

Part 96 at a glance
Maximum EIRP is per 10 MHz, from 47 CFR § 96.41(b). Rule text as of 2026-09-29.

max EIRP per 10 MHz · about 50 WAn outdoor Category A antenna above 6 m HAAT, or any Category A device above 30 dBm, is classified as Category B (§ 96.43). An end user device above 23 dBm is classified as a CBSD (§ 96.47(b)).
HAAT is the antenna’s height above sea level minus the average ground elevation 3–16 km away in eight directions. On a hilltop, even a short mast can exceed 6 m HAAT. In a valley, an antenna can sit well above 6 m off the ground and stay below it. The map calculates HAAT with the FCC’s terrain service and shows the tallest outdoor Category A mount for the point you choose.
When a Dynamic Protection Area is activated, a SAS adds up interference from CBSDs registered in its neighborhood and can lower their power or move them to another channel. NTIA lists six distances per DPA: Category A outdoor, Category A indoor, and Category B, each for antennas at or below 6 m above ground and above 6 m. The map draws the one that matches your configuration.
