When AT&T built the first microwave relay from New York City to Chicago in the late 1940s for long-distance telephone service, this tower was the first in line after New York. It may not be the original structure, but it is the original site and uses the same kind of large microwave horns, which likely have not been in active use since the 1980s. Due to its ideal hilltop location, the structure likely serves today as a cell phone tower. Its access road has also been turned into a housind development, called Tower Road.

  • @monicatov Your conspiracy theory is about 25 years out of date, as these large microwave horns haven't been used since the 1980s.

  • Although some websites incorrectly list the Martinsville site as a concrete silo - the tower as pictured in the posted video is the original as erected by AT&T. There is also a permanent building housing transmission and support gear.

    This tower originally had quite a few more microwave antennas (mostly horn type) than it does today. The site is no longer owned/operated by AT&T.

  • The article "34 Jumps to Chicago" from the Sept. 1949 Long Lines magazine (as found on long-lines . net) shows a photo of a 101-foot concrete silo being constructed at Martinsville, so unless they mislabeled the photo, I think that part is true, and the silo was replaced by the metal structure in later years. American Tower has many detailed photos of the current Martinsville tower on their web site.

  • wow I didn't know they had microwave telephone towers in the 40s! that seems like something they'd use now! actually cell phone towers are also microwave, I wouldn't want to live near one though!

  • The microwave towers were primarily built to carry TV networks, with radio and telephone also sharing the bandwidth.  Many of the microwave towers -- including this one -- were originally built as concrete silos, due to the scarcity of steel during and after WWII.

    Google "34 Jumps to Chicago" (with quotes) for a great article from 1949 about the network. Notice the lack of Interstate highways on the maps in the background -- they didn't exist until the '50s!

  • the original AT&T that owned these is defunct. SBC corp. bought AT&T in 2005 and changed their name to at&t (note lowercase) so SBC definitely doesn't care about their towers.

  • The glove on top is probably a unclear blast detector to be used during the cold war.

  • Y cant that be in my backyard

  • I remember seeing those in Massachusetts too. used to be a big one in Paxton. The round ball on top looks like some sort of Doppler radar though.

  • There's one by my house in new tripoli Pennsylvania there's a hiking trail going right past it

  • beautiful!

  • @vwestlife I really want to know what that big radome on the top of that tower was for, checked google, came up with nothing other than that tower was originally a TD-2 (big square horn) microwave site, but no mention of a radome. There has to be someone out there on youtube who knows.

  • Ball in the middle looks like an X-band missle sniffer or doppler radar.

  • very kewl video-thanks for sharing!
