How many radials do NDBs have?

Non-Directional Beacons (NDBs) operate by emitting radio signals in all directions. Unlike VORs (VHF Omnidirectional Range) that provide specific radials, NDBs do not have predefined radials as they do not rely on directional transmission. Instead, pilots use ADF (Automatic Direction Finder) equipment to determine the direction to the NDB from their aircraft, which can receive signals from all 360 degrees. Therefore, assigning a number of radials to NDBs is not applicable, reinforcing that they essentially have zero assigned radials. This fundamental characteristic distinguishes NDBs from other navigational aids that offer structured radial information.
