This relay site was constructed on Clarks Knob at an elevation of 2,338 feet above mean sea level in Letterkenny Township, Franklin County, Pennsylvania. The site is located within the Buchanan State Forest and it appears to have been one that Western Union leased from the State of Pennsylvania. The site in 2004 was controlled by the Pennsylvania Turnpike Commission.

Western Union constructed a 60-foot tower at this relay site. The tower and cab remain intact; however, the equipment building has been replaced. This relay station was one of the first generation sites modified by Western Union to accommodate a second equipment cabin on the platform beneath the upper cab. Alterations to this tower include mounted parabolic and whip antennas.

One thought on “Western Union microwave relay sites: Blue Mountain relay, Pennsylvania

  1. The lower of the two cabins was actually a fire lookout cabin used by the PA Dept. of Forestry. It was originally part of the departments Clarks Knob fire tower, and was moved to the Western Union tower when it was built in in July 1945. The fire lookout tower was removed at that same time.
