Template:Antenna Structure Registration database/doc

Usage
This is for linking to FCC ASR entries. Usage is as follows:

The number is the official FCC Registration number. It appears to be always 7 digits, starting with "1", and is displayed prominently in the registration entry. Including it in the template is optional, but highly recommended.

The key is the internal record identifier, appearing as the "?regKey=" part of wireless2.fcc.gov URLs. It has no direct relationship to the registration number, and may or may not be remain stable.
