We’re excited to share a major upgrade to the WSHE379 GMRS repeater system happening this weekend! On March 21, 2026, we will be installing a new 7-element Yagi antenna to enhance our coverage and overall performance.
This upgrade brings a significant improvement in signal strength, with the new antenna providing approximately 11 dB of gain. In practical terms, that means a much stronger and more focused signal compared to our current setup. An 11 dB gain increase can effectively multiply our radiated power in the desired direction, allowing signals to travel farther while maintaining clarity and reliability.
One of the key advantages of a Yagi antenna is its directional capability. Unlike omnidirectional antennas that spread signal equally in all directions, the 7-element Yagi concentrates energy in a specific direction. For our installation, this beam will be oriented westward, allowing us to strategically expand coverage where it’s needed most.
This means improved reception and transmit performance along the I-65 corridor and into the Hartselle area, with:
- Stronger signal penetration into buildings and mobile environments
- Reduced signal dropouts while traveling along I-65
- More consistent coverage in previously weak or fringe areas
- Improved overall audio quality for stations in the west coverage zone
- Additionally, the directional nature of the antenna helps reduce interference from other directions, making the repeater more efficient and reliable for all users.
We’re looking forward to hearing your signal reports after the installation. As always, your feedback will help us fine-tune and optimize performance.
Thank you for your continued support of the WSHE379 repeater system!
