      The tower is a Microflect HD-65 (High Density) that was offered as an alternative to the standard RC&R towers. The design is a 30.5-ft square non-tapered tower that was available in heights of 65-ft to 140-ft in 12.5-ft increments.

      The tower could support up to eight horns - four on the main-deck corners and four on the diagonally-mounted top deck. Tower height was measured to top deck so an HD-65 tower with just the main deck was actually 50-ft tall; single-deck HD tower heights ranged from 50-ft to 125-ft.

      HD series towers mainly appear in Oregon and Washington due to Microflect's original location in Salem, Oregon. Microflect was subsequently acquired by Valmont - known for large center-pivot irrigation systems used in flat farm country marketed under the brand Valley Irrigation.

      Some sites with Microflect HD towers:
      Amity HD-65 1-Deck
      Crescent Butte HD-90 1-Deck
      Hoodoo Butte HD-65 2-Deck
      Mt Horeb HD-77.5 1-Deck
      Saddle Mt HD-65 2-Deck
      Spring River HD-65 1-Deck
      Welch Butte HD-102.5 1-Deck

      Joe Butte HD-115 2-Deck
      Lebam HD-65 1-Deck

      This list may not be all-inclusive - wa -
