Dielectric completes Lookout Mountain DTV transmission project serving Denver

Dielectric Communications has provided antennas, transmission line and a complete RF system for a new tower site that has brought high-power DTV broadcasts to the Denver metropolitan area.

The new installation serves Lake Cedar Group, an organization that represents Gannett Broadcasting-owned KTVD (a MyNetworkTV affiliate) and KUSA (an NBC affiliate), McGraw Hill-owned KMGH (an ABC affiliate) and CBS owned-and-operated KCNC. The system is currently on-air and broadcasting signals for all four stations.

This custom-designed RF system with three VHF antennas and three UHF antennas allows six channels to operate in both main and alternate configurations for VHF channels 7 and 9 and UHF channels 16, 17, 19, and 33. Previously, the channels were limited to transmitting low-power digital signals from the tallest building in downtown Denver.

By airing signals from the new 730ft tower located on Lookout Mountain west of Denver, KCNC, KMGH, KTVD and KUSA benefit from greater transmission performance and streamlined, merged operations that reduce the number of towers visible on the mountain.

To minimize the impact of the transmission facilities on the appearance of the mountain, several major network broadcasters share a single tower and a 250ft underground tunnel is used to house the 10 phased transmission line runs.
