What customers say
The Intellitron AM-2133M earns high praise, especially for portable operations like POTA. Users value its exceptional height to weight ratio, easily achieving 33 feet from a backpack portable package. The fiberglass construction offers inherent safety advantages over aluminum alternatives. Setup is remarkably fast, often under ten minutes, making rapid deployment simple. While robust for lightweight wire antennas, users note it requires careful guying in wind. Some long term feedback mentions that locking collars need diligent cleaning to prevent slippage. Despite a premium price, the specialized utility and field reliability deliver excellent value for dedicated amateur radio operators needing portable elevation.
Know before you buy
The AM-2133M is designed for lightweight amateur radio antennas. While it supports its own structure with minimal guying, it is best suited for portable wire antennas or lightweight VHF/UHF beams rather than heavy, high-wind-load arrays.
The mast is engineered for stability, but for maximum safety and to prevent swaying, we recommend using a guying kit, especially when fully extended to 33 feet or in windy conditions.
The friction twist-lock system is designed for quick, reliable adjustments. To maintain its grip, keep the fiberglass sections clean and free of grit or sand, which can interfere with the locking mechanism.
Yes, the mast collapses to a compact 3 feet, 9 inches. This makes it highly portable and easy to fit into the trunk of most cars or store in a gear bag for field operations.
Yes, the top section is designed to accommodate standard antenna mounting hardware. The top outer diameter is 5/8 inch, so ensure your antenna mount is compatible with that specific dimension.
The redesigned base provides significantly improved structural integrity at the point of highest stress. This reinforcement helps prevent cracking or deformation when the mast is fully extended and under load.
