Sioux City, Iowa · Woodbury County
Overview
This tower in Sioux City, IA carries FCC registration 100389. Its overall height is 154 m (505 ft) above ground, putting the top at 578 m above sea level.

The registrant is Community Broadcasting, INC., a broadcaster. Structures registered to broadcasters usually carry the station's own transmitting antenna rather than leased wireless equipment.
At 154 m, the radio horizon for an antenna at the top of this structure works out to roughly 51 km (31.8 mi). That is a geometric limit for flat, unobstructed terrain — real coverage depends on transmit power, frequency, terrain and what is in the way.
This is a dense cluster: 10 other registered structures fall within 5 km, the closest just 74 m to the NW.
Iowa has 1,118 registered structures of this type, and this is one of them.
