Tolong jelaskan mengenai FCC broadcasting tower database dari FCC dalam bahasa sunda

The FCC database of broadcasting towers   is a very useful tool to get information about the height and yéar built of broadcasting towers in the USA. However, this database does not contain information about the structural types of towers.

The FCC database also does not contain information about the height of towers used for non-broadcasting purposes like NDBs, LORAN-C transmission towers or VLF transmission facilities of the US Navy, or from towers not used for transmission at all like the BREN-Tower.
