Rohn 25G 40′ Basic Tower Kit

The Rohn 25G 40′ Basic Tower Kit provides a field-ready, accessible structure for RF antennas. The kit includes multiple 10′ sections plus a top section, with a 40′ nominal height that can adjust downward when embedded in concrete. Key construction features include double bolted joints for sturdy connections, hot-dipped galvanization for corrosion resistance, and a triangular 11 1/4″ base design. This kit is designed for professional installation, ensuring alignment and support under wind and load conditions typical in many sites. Consider professional mounting and concrete work requirements in the installation plan.
Included components emphasize compatibility with 1-1/4″ OD, 16 gauge legs and 5/16″ OD solid bracing. The combination of robust bracing and galvanized finish supports long-term performance in outdoor environments. If your site requires a taller, stable tower with proven reliability, this ROHN kit is a balanced option for amateur radio or other communications needs, especially when compatible with standard Rohn accessories.
Rohn 25 Series 40′ Basic Tower (25G)

The Rohn 25 Series 40′ Basic Tower (25G) mirrors the standard 25G design with a 40′ nominal height description. This kit emphasizes double bolted joints for resilience, galvanized fabrication to resist weathering, and a triangular base footprint for structural integrity. As with other 25G configurations, the actual final height may be reduced if the lower section sits in concrete. The kit includes multiple 10′ sections and a 9’9″ top segment, aligning with common installation practices for modestly tall antenna deployments. Expect straightforward assembly for installers familiar with Rohn towers and ensure proper anchoring and alignment during setup.
With 1-1/4″ OD, 16 gauge legs and 5/16″ OD bracing, this kit offers a reliable platform for rooftop or ground-level installations. The galvanized finish extends service life, reducing maintenance. This model suits enthusiasts seeking a standard, mid-range tower kit with scalable components and compatible accessories from the 25G family.
ROHN 25SS040 40′ Self-Supporting Tower, No Ice

The ROHN 25SS040 is a 40′ self-supporting tower kit designed for environments where a guyed system is not preferred. The package includes three 25G standard 10′ sections, a 9’9″ top section, and a concrete-compatible base (SB25G5) for embedment. An anti-climb warning sign kit (ACWS) is included, underscoring safety and compliance concerns for unattended installations. The 25G standard components maintain double bolted joints and full galvanization, ensuring durability. The kit’s self-supporting nature means it carries the structural load without external guy wires, which can simplify installation on solid foundations or rooftops with adequate load-bearing support.
Material dimensions include 1-1/4″ OD, 16 gauge legs with 5/16″ OD solid bracing. Fully hot-dipped galvanized fabrication adds longevity in harsh outdoor conditions. This kit is ideal for those who require a freestanding tower with integrated base support, while maintaining the familiar Rohn 25G construction standards and installation guidance.
ROHN 45G Series 40′ Kit

The ROHN 45G Series 40′ Kit is tailored for installations demanding a broader 40-foot scope within ROHN’s 45G family. The kit includes four 10′ standard sections, a 5′ concrete base, and a top plate, creating a strong self-supporting tower assembly. Like other 45G configurations, this kit emphasizes double bolted joints, full galvanization, and a 16 3/4″ equilateral triangle base for stable footing. The 14 gauge legs paired with 7/16″ OD bracing provide enhanced rigidity to withstand wind loads and environmental exposure. This option suits sites that require a heavier-duty structure with a concrete base for added stability. Professional installation is advised to ensure correct base preparation and alignment.
While 40′ nominal, the actual height can vary slightly due to embedding depth. The kit’s galvanized finish and robust base system make it a practical choice for longer-term deployments in more demanding climates or locations with higher wind exposure.
Easy Up 27′ 7″ Telescoping Mast

The Easy Up 27′ 7″ Telescoping Mast offers a shorter alternative for installations requiring a portable or temporary mast. While not a fixed 40′ tower, its telescoping design and multiple sections enable height adjustments and compact storage. The kit features sections with varying diameters (2″ to 1-1/4″ OD) and gauges (18-16 GA), with a rotating guy ring system and adjustable collars for height control. This model suits temporary deployments for antennas, security cameras, or other line-of-sight needs where quick assembly and disassembly are advantageous. Clear mounting considerations and compatible accessories help ensure reliable performance in transient setups.
For longer-term or permanent installations, pairing an Easy Up mast with a fixed base or anchoring system can provide flexible options, but users should assess wind load and structural requirements before relying on temporary masts for critical communications.
Easy Up 20′ 9″ Telescoping Mast

The Easy Up 20′ 9″ Telescoping Mast provides a compact, portable option for shorter-range deployments. Fully assembled height reaches 20′ 9″, with a collapse-to-5′ storage profile for transport. The mast sections progress from 2-1/4″ OD to 1-1/4″ OD in a stepped configuration, all within 18 gauge construction. The overlapped top section enhances rigidity and load-bearing capacity. This option is suitable for temporary setups, demonstrations, or portable antennas where quick deployment and ease of handling trump the need for a fixed, tall structure.
Despite its portability, consider the mast’s load limits and the intended antenna weight, ensuring that the system remains safely within recommended wind and support thresholds for its height and base design.
Buying Guide: 40 Ft Tower Options And Key Considerations
Choosing the right 40 ft antenna tower kit involves evaluating structure type, installation site, load requirements, and maintenance expectations. The following factors help buyers compare options across the ROHN family and telescoping mast alternatives:
- Self-supporting vs. guyed: Self-supporting towers simplify installation on solid foundations but may require greater mounting strength, while guyed towers accept longer spans and higher loads with guy wires, often lowering cost for certain sites.
- Material and finish: Look for hot-dipped galvanized steel for outdoor durability. Corrosion resistance ensures longer life with minimal maintenance, especially in salty or humid environments.
- Section design and joints: Double bolted joints enhance sturdiness and ease of field assembly. Check the availability of replacement parts and compatible accessories in your region.
- Height reality vs nominal: Many kits note a nominal 40 ft height; actual height can be lower if parts are embedded in concrete or due to top section differences. Plan for site tolerances in mounting.
- Base and embedment: Concrete bases (or non-embedment bases) affect install time and foundation requirements. Anti-climb signs and safety kits may be included or recommended for certain deployments.
- Weight and wind loading: Larger towers demand careful wind load calculations and anchoring. Ensure your anchor points and foundation can support the anticipated loads for the antenna payload.
- Delivery and logistics: Some kits ship freight and require coordinating delivery and on-site placement. Verify access, handling, and scheduling needs for your project.
- Long-term maintenance: Consider accessibility for inspection, bolt tightness, and potential repainting or re-galvanization over time to preserve structural integrity.
When evaluating these 40 ft options, align the tower type with your antenna system, local building codes, and the available land or rooftop footprint. If you anticipate future expansion, prioritize modular kits with common sections and compatible bases. Finally, professional installation is advised for most of these systems to ensure proper anchoring, grounding, and alignment, maximizing performance and safety.
