Diamond Antenna Yagi Support Brackets
Best mounting solution for radio enthusiasts optimizing vertical Yagi antenna performance.
Optimize your vertical polarization setup with the Diamond Antenna Yagi Support Brackets (KB144). These brackets are essential for side mounting VHF or UHF Yagis, preventing performance degradation caused by vertical mounting directly on a metal mast. Utilizing these boom supports dramatically enhances performance, especially for FM operations. They are designed to securely fit masts up to 1.750 inches in diameter. Note that these supports are specifically beneficial for vertical polarization and are not required when mounting horizontally. They are particularly recommended for use with the Diamond Antenna model A144S5.

This product is highly recommended for permanent, high-power installations where unwavering structural support is paramount.
Know before you buy
When mounting a Yagi antenna vertically on a metal mast, the mast can interfere with the antenna's radiation pattern and degrade performance. These brackets provide the necessary offset to prevent that interference, ensuring your signal remains clear.
No, these support brackets are specifically designed for vertical polarization setups. They are not required for horizontal mounting configurations.
The KB144 brackets are designed to securely clamp onto masts with a maximum diameter of 1.750 inches, or 44.45 mm.
While they are designed for Diamond VHF and UHF Yagis and are specifically recommended for the A144S5 model, they are intended for antennas that require side-mounting for vertical polarization. Always verify your specific antenna's mounting requirements before installation.
Yes, the Diamond Antenna Yagi Support Brackets are sold as a complete kit, providing all the necessary components to mount your antenna to the mast.
