This is KVLY-TV's older channel-11 analog transmitter, an ancient General Electric that was almost certainly installed when the tower was built in 1963. It has operated as KXGO-TV, KEND-TV, and KTHI-TV (“HI” as in “high” antenna); I didn't ask if it had seen any service as KVLY-TV, which has only been the callsign since 1995.
