  2. Height is Everything - Higher placement = better coverage
  3. Line of Sight - Works best with unobstructed path
  4. Network Healing - Mesh automatically finds routes
  5. Power Management - Lower TX power extends battery

Common Mistakes

  • Poor Antenna - Stock antenna works but limits range
  • Low Placement - Keep devices elevated
  • Too Many Hops - Limit hop count for better delivery
