Recommended offset distance for an NRG side mount boom

On a tubular (NRG) tower, it is recommended that the offset distance of the side mount boom be at least 7 tower diameters out from the tower. For a 40m or 50m NRG tower the tower diameter is 6 inches. For XHD towers the diameters are 10" and 8".


For 40m and 50m NRG TallTowers:

  • 6 inches x 7 = 42 inches in length

For 50m and 60m XHD TallTowers:

  • 8 inches x 7 = 56 inches in length
  • 10 inches x 7 = 70 inches in length
