Tram 1480-B Fiberglass Base Antenna (8’4″)

Using fiberglass for the structural column, the Tram 1480-B offers robust high-power handling and a length suitable for supporting UHF and VHF elements. Its two-section fiberglass construction is designed to withstand exposure and maintain alignment under typical wind loads. This model includes an 8-foot-plus overall height, enabling a taller mast for improved line-of-sight. The unit’s 50-ohm UHF SO-239 connector supports a range of antennas, delivering reliable signal transfer with minimal corrosion concerns.
Key advantages include strong resistance to bending under moderate wind, low thermal expansion, and a non-conductive exterior that reduces shielding effects near sensitive equipment. Consider this option if you need a fiberglass-based mast with proven high-power compatibility and a taller, stable profile for outdoor installations.
5′ Galvanized Steel Mast With Swaged End

This 5-foot mast uses galvanized steel with a 1.25″ outer diameter and a 20-gauge wall. While not fiberglass, it provides a sturdy, economical option for shorter installations or where wind exposure is moderate. The swaged end helps connect to other mast segments or mount hardware with reliable alignment. Suitable for compact setups, it supports various off-air and small-dish configurations while resisting rust in outdoor environments.
Easy Up 20′ 9″ Telescoping Mast

This telescoping mast is designed for versatility, expanding to a full 20 feet 9 inches yet collapsing to just 5 feet for transport. Its steel construction and sequential sections (ranging from 2-1/4″ OD to 1-1/4″ OD across sections) provide solid rigidity. Overlapped sections add strength, making it suitable for roof or yard installations where height is critical. The friction-fit or collar-based height adjustments offer straightforward installation, with a focus on stability in varying weather conditions.
Easy Up 1-1/4″ Od x 5′ Swaged End Mast

This Easy Up EZ5-16SW mast features a 1.25″ diameter and a 5-foot length with a 16-gauge steel construction and a clear coat zinc finish. The zinc coating helps resist corrosion in outdoor settings, while the swaged end provides a clean, strong join for expanding into longer configurations. It is a compact, reliable option for lightweight antennas or test installations where height is moderate and portability matters.
Easy Up 21′ 6″ Telescoping Mast (EZ TM 30-U-95)

This mid-length telescoping mast offers a balance between height and manageability. With a 21-foot-6-inch assembled height, it uses a stepped diameter approach (bottom to top) for strength: 1-3/4″ OD, 1-1/2″ OD, and 1-1/4″ OD sections, culminating in a 1-1/4″ top rod. Features like rotating guy rings and a sturdy thumbscrew/collar system simplify setup and height adjustment, making it suitable for medium-range signal needs where elevation is important but transportability remains a consideration.
Easy Up 33′ 2″ Telescoping Mast (EZ TM-50-U-95)

This model provides a full 33 feet 2 inches of assembled height with a 95-inch collapsed length. The bottom section measures 2-1/4″ OD, followed by 2″, 1-3/4″, and 1-1/2″ diameter sections, all with 18-gauge steel and a long top section of 1-1/4″ OD. All sections come pre-galvanized and are clear-coated for added corrosion resistance. The long height is ideal for maximizing line-of-sight and over-the-hadge clearance for long-range reception or transmission.
Buying Guide: Key Considerations for Fiberglass and Related Mast Sections
When selecting a mast, buyers should evaluate material performance, mounting compatibility, and environmental exposure. Fiberglass sections generally offer insulating properties and reduced corrosion risk, while metal masts (steel or galvanized steel) provide high strength and stiffness. Here are critical factors to compare:
- Material and corrosion: Fiberglass resists corrosion and conducts less heat, offering stable performance in wet or salty conditions. Steel versions rely on galvanization or coatings to withstand rust; consider coastal installations or humid climates.
- Height and adjustability: Telescoping masts enable flexible height management for line-of-sight optimization. Check the number of sections, minimum/maximum heights, and locking mechanisms.
- Strength and wind tolerance: For outdoor use, evaluate wind ratings and the mast’s ability to support antenna weight without excessive flex. Heavier, thicker sections often perform better in high winds.
- Mounting compatibility: Ensure diameter specs (OD) align with your antenna mounts, guy rings, and base hardware. Swaged ends simplify joining sections but verify compatibility with existing hardware.
- Ease of transport and installation: Longer telescoping models add height but require more effort to assemble. Lighter options may be preferable for rooftop installations or portable setups.
- Coatings and finishes: Zinc or clear coatings extend life by reducing corrosion. Pre-galvanized parts tend to resist rust in outdoor environments; fiberglass components may have surface finishes that enhance UV resistance.
- Maintenance needs: Inspect joints for wear, check set screws or collars for tightness, and replace worn sections to maintain signal integrity and safety.
In practice, fiberglass-based masts like the Tram option can offer a weather-resistant, non-conductive exterior that minimizes potential interference with antenna elements. However, for some installations, galvanized steel or coated steel masts provide superior stiffness and load-bearing capacity at a lower cost. Evaluating the specific antenna type, mounting position, and local weather conditions will guide the best choice.
For installations requiring long reach or rooftop visibility, telescoping steel masts provide flexible height with robust construction. Shorter or lighter setups benefit from compact, swaged-end or zinc-finished sections that are easier to handle and assemble. Buyers should balance height needs, wind exposure, and ease of installation when choosing among fiberglass and metal mast sections.
