Tower array 118900
Oakland, California · Alameda County
Overview
A tower array element of 79 m (258 ft), structure 118900 has stood about 10 km (6.3 mi) from Oakland, CA for about 61 years.
Locally it is the 3rd tallest of 51 registered structures about 10 km (6.3 mi) from Oakland, CA.
The structure is registered to Capstar Radio Operating Company, which holds 11 registrations across California.
At 79 m, the radio horizon for an antenna at the top of this structure works out to roughly 37 km (22.7 mi). That is a geometric limit for flat, unobstructed terrain — real coverage depends on transmit power, frequency, terrain and what is in the way.

About this record
One element of a 3-tower array. Multi-tower arrays are typically AM broadcast antennas, where the towers work together to shape the signal in a particular direction.
Source data is the FCC ASR record for structure 118900, which gives a construction date of 1965. Registrations are updated when a structure changes, so figures reflect the most recent filing rather than continuous monitoring.
"Owner" is the entity that registered the structure, usually a tower company such as American Tower or Crown Castle. It does not indicate which carriers operate equipment on the structure.
