Farnsworth Peak, Mountain summit in Tooele County and Salt Lake County, United States

Farnsworth Peak is a summit at the northern end of the Oquirrh Mountains, about 18 miles southwest of Salt Lake City. It rises 2,760 meters, roughly 379 meters above the surrounding terrain, and its slopes carry the transmission towers of three separate sites: Big Farnsworth, the KSTU Site and Little Farnsworth.

The peak is named for Philo Farnsworth, inventor of the first fully electronic television. KSL-TV was the first station to broadcast from the mountain, and the site later became one of the first in the United States with a facility built specifically for digital television transmission.

The peak's transmitters carry most Salt Lake City FM signals and stations such as KSL-TV, KSTU, KUCW and KUTV. Its ham radio repeaters link western and southern Utah to the Intermountain Intertie hub atop Hidden Peak. KSL-TV was the first station to broadcast from the mountain and keeps engineers on site for emergencies.

The eastern approach is not generally open to visitors due to private land, but the western side from Tooele provides public hiking routes to the summit. The Tooele approach offers easier access for those looking to reach the top.

The summit holds three separate transmitter complexes: Big Farnsworth, The KSTU Site, and Little Farnsworth, forming a layered communication network. This multi-site infrastructure makes it a major hub for broadcasting across the entire valley.
