Topics Covered

Page 9: 80m XHD Webinar Slides

Resources and Time• Site layout / anchor setting: 1 day• Tube bolting: 3.5 hours• Laying out guy wires: 3.5 hours• Ginpole assembly: 1.5 hours• Lighting installation: 2.5 hours• Raising & plumbing tower: 3.5 hours

TOTAL: 3-4 days

Installation

Page 10: 80m XHD Webinar Slides

80m XHD Terrain/slope Requirements• Terrain/slope ≤ ±3°

Slopes greater than +1.5° Slopes less than -2°

Installation

Page 11: 80m XHD Webinar Slides

• Double Helix Power-Installed Screw Anchors.

• Maximum anchor load: 12,400 lbf (5625 kgf).

• CRITICAL STEP:Anchors must be pull-tested to 15,000 lbf (6804 kgf).

Installation

Anchors and Pull Test 1

Page 12: 80m XHD Webinar Slides

1. Hold top fastener up while tubes are slid together.

2. Using a block of wood and sledge hammer, pound 2 to 3 times to seat joint.

3. Using a torque wrench, torque 5/8” – 11 nuts to 203 Nm (150 ft-lbs).

Installation

Joint Assembly

Page 13: 80m XHD Webinar Slides

• CRITICAL STEP:Jumper-strut cables must be tensioned to 1000 lbf using provided tension gauge.

Installation

Ginpole and Jumper-struts2

Final Thoughts

• 60m XHD performance at 80m

• More steel means more weight

• Similar installation, new tools and anchoring required

• Thoroughly review the 80m XHD Manual
