Sabre Tower Modifications

Sabre offers complete turnkey tower and monopole modifications. Providing you with speed to market, we have the experience and capability to design, fabricate and install tower and monopole upgrade components.

Our services include:

  • Tower and foundation mapping
  • Structural analysis
  • Modification design and detailing
  • Material fabrication
  • Installation of tower upgrade materials, mounts, antennas and line

Sabre’s in-house engineering team utilizes an industry-accepted software program that enables them to accurately and efficiently perform structural analyses. The Structural Analysis Report is sealed by a registered professional engineer and indicates if modifications are required. In addition to engineering, we provide in-house fabrication and installation of upgrade components.

Monopole Modifications

Sabre manufactures a full range of monopole modifications. Fabricated and galvanized in our state-of-the-art facilities, we can supply you with superior quality and quick turnaround. Our monopole components are designed for safety in the field. Welded in our facility prior to shipping, they provide zero to minimal field welding.

Self-Supporting and Guyed Tower Modifications

In addition to monopole modifications, Sabre offers a full line of tower reinforcement components that are designed specifically for tower upgrades and reinforcing projects. These components immediately fit most manufacturers’ self-supporting and guyed towers, or can easily be adapted to less common models. Designed to fit the first time, our tower upgrade components are optimized for ease of installation and minimum interference with existing mounts and lines.

Sabre delivers the same service on tower modifications as on our new towers. We offer quick response times for quotations, shorter lead times for fabrication and delivery, and on-schedule installations. Contact us toll free at (800) 369-6690 or via email at
