TL;DR

For GMRS and MURS, the optimal Signal Strand™ length depends on your antenna type:

• Dual-Band Signal Stick™: ~16.5"
• 440 Monoband Signal Stick™ (GMRS only): ~5.25"

Understanding the Lengths

The Signal Strand™ wire acts as a counterpoise, improving antenna performance by balancing it. The ideal length varies based on the operating frequency and antenna type:

• GMRS (462-467 MHz) and MURS (151-154 MHz): Use ~16.5" with a Dual-Band Signal Stick™.
• GMRS only: Use ~5.25" with a 440 Monoband Signal Stick™ for better single-band performance.

Can I Use Other Antennas?

The provided lengths are specifically tuned for Signal Stick™ antennas. While they may work with other antennas, performance can vary based on the design. Feel free to experiment to find what works best for your setup.

In Summary

• Dual-Band Signal Stick™: ~16.5" for GMRS and MURS
• 440 Monoband Signal Stick™: ~5.25" for GMRS

Cut your Signal Strand™ to these lengths for optimal performance.
