    AI Overview
    Tubular microwave towers are self-supporting or monopolar structures made of hot-dip galvanized steel, widely used in telecommunications for transmitting microwave, radio, and cellular signals. Designed for structural stability, they often support 3-4 legs or a single tubular column to carry heavy antenna loads. Historically, similar towers formed the backbone of AT&T's Cold War-era "Long Lines" network. 
    Key Aspects of Tubular Microwave Towers: 
    • Structure & Material: Typically constructed from hot-dip galvanized steel or aluminum alloys for high corrosion resistance and structural strength.
    • Types:
      • 3-Legged Tubular Towers: Versatile, self-supporting structures often 20m to 60m high, used for heavy communication loads.
      • Monopole Towers: A single tubular structure preferred for urban environments due to its compact footprint.
    • Components & Performance: Designed to support multiple microwave dishes and cellular equipment, engineered to withstand high wind speeds and harsh weather conditions.
    • Applications: Primarily used for transmitting data, TV signals, and voice traffic over line-of-sight networks (often 30–40 miles apart) and for modern 5G/railroad communication systems.
    • Legacy: Many historic, large-diameter tubular towers from the AT&T "Long Lines" network, built in the 1950s/60s, have been decommissioned or repurposed for modern cellular use.
