Important Notice: 5.0 BETA Firmware

You have selected 5.0 BETA firmware. BETA firmware is a pre-release version that includes new features and improvements, while rare, BETA firmware could contain bugs or usability issues. Please consider the following information before proceeding:

What is BETA Firmware?

  • Early Access: BETA firmware allows early access to new features that are not yet available in Stable Releases.
  • Testing and Feedback: It is intended for users who are willing to provide feedback and help identify any bugs or issues.
  • Potential Risks: There may be minor bugs, feature limitations, or performance issues.

Important Considerations

  • Are you comfortable troubleshooting and reporting any issues?
  • Do you understand the steps required to revert to a Stable Release if needed?
  • Do you have time to update your firmware more frequently, knowing that some updates may require a wireless reprogrammer?

Recommended Action

If you are not familiar with BETA testing, we recommend selecting the Stable Release version instead for the highest level of stability and support. For more details on our firmware release process, please review our complete guide here. If you have questions or need further assistance, please reach out to our support team.

Use this 3M (9.75 ft.) extension cable to raise or re-position your antenna for better line-of-sight. You simply connect the extension cable to your 18R, 18R2, or 18M, and connect the antenna to the other end of the cable. Use a zip tie to mount the antenna to a wooden dowel or any other surface. Extension cables are commonly used to raise the height of the antenna when shooting from further distances or where you have small increases and decreases in elevation between the shooter and the firing modules.

Also note that any extension cable will decrease the signal strength slightly, however the improvement from better line-of-sight will commonly outweigh the loss. A 3M (9.75 ft.) extension will have a -6 dBm loss when using the COBRA signal strength test. As a general rule of thumb, if a module is 200M (600 ft.) away on the ground level, you will see a minimum 5-10 dBm improvement by raising the antenna 1M (3 ft.) off the ground.
