Quick answer
Protection runs from 1 to 10. Values 1 to 3 are Strong, 4 to 6 Adequate, 7 to 8 Limited, and 9 to 10 Remote. Lower values indicate stronger routed station access.
Why it matters
Polarity prevents a common mistake: treating 10 as the strongest result. Read the band beside the number and review miles, minutes, and station type.
Limits and next step
The number addresses response access rather than building resistance or wildfire likelihood. Check a US street address for the applicable route.
