Telescopic Unguyed Antenna Tower

Is an Aluminum Self-Supporting Telescopic Tower Right for Your Site?

The T2 aluminum self-supporting telescopic tower works best where traditional guyed systems are ineffective. Aluma Tower Company recommends the T2 for sites with limited space — urban rooftops, industrial yards or event venues — where guy anchors would get in the way or aren’t feasible.

Rapid deployments benefit from the T2 model’s self-supporting design, which eliminates time-consuming anchor installation.

Common Use Cases

Aluma Tower Company’s T2 serves diverse communication and sensing needs. For communications, the T2 supports:

  • LTE and 5G small cells
  • LMR and P25 repeaters
  • Point-to-point microwave links
  • Satellite terminals

For sensing and surveillance, it handles PTZ and thermal cameras, high-intensity lights and environmental monitoring equipment.

Overall, this model offers real benefits to the operating team. Self-supporting operation within published limits eliminates guying hassles. Electric winch systems with limit switches and safety interlocks enable fast, repeatable raising and lowering. Crews get operational faster. Physical work is reduced. Most importantly, safety is maintained throughout deployment.

Considerations: Height, Payload and Wind

Selecting the right T2 means balancing three factors — height, payload and wind exposure. Choose height based on your coverage needs and line-of-sight requirements. Aluma’s T2 family ranges from 39 feet to 106 feet with top mast extensions, covering everything from local events to regional networks.

Payload means both weight and surface area. Your headload includes equipment weight in pounds or kilograms, plus the exposed surface area of antennas, panels and dishes in square feet. Match your equipment and target height to the right T2 model’s published limits.

Wind matters for configuration. Unguyed T2 operation is rated to 70 mph. Guyed setups extend to 90 mph. High-wind areas or large antennas require guying or a different tower. Check the T2 spec table to determine which model is best for your needs.

Aluminum Telescoping Masts Without the Need for Guy Wires

Lightweight and unguyed, these self-supporting aluminum telescoping towers are a crucial component for rapid deployment and quick mobility in many urban or rural settings. Aluma has developed simple, cost-effective designs that are mission ready or available to be custom fitted for your unique requirements.

SMART tower

Self-Supporting Antenna Tower

Our stout T2 series is Aluma’s version of an unguyed, self-supporting antenna tower which can be freestanding or coupled to a trailer for mobile telescopic solutions.

Testing the Aluminum Telescoping Tower Mast

Major Air Force Base Test and Evaluation has raised and lowered our unguyed slide bar tower over 5,000 times.  Minimal maintenance required a cable change every 1,000 repetitions and a pulley change every 2,000 repetitions.  This dependability has allowed our T2-100UG model unguyed tower to become a solid leader in the 100 ft tower category.  It is ideal as a trailer mounted mast for a cell tower trailer.  It is also popular with our SMARTTM technology, which monitors weather conditions to determine if the tower is in jeopardy and notifies the operator to lower the tower to avoid damages. Our SMARTTM technology can also be configured to take action autonomously.

Mounting and Deployment Scenarios

The T2 model can adapt to different operational needs. Mobile deployments pair T2 towers with Aluma trailers for rapid response without guy-line complications. Building-mounted setups use the T2 on rooftops where structure allows and local codes permit bracket mounting. Lastly, freestanding installations work in tight spaces where guying is not wanted or possible.

Common deployments include mobile cell-on-wheels trailers for disaster recovery and temporary network capacity during emergencies or events. Semipermanent installations use the T2 model’s small footprint where space is tight or lease terms require minimal ground impact.

It’s important to note that the T2 model isn’t designed to support a payload weight, antenna size or wind exposure that exceeds the tower’s unguyed limits. In those cases, consider Aluma’s other tower families designed for heavier loads or extreme winds.
