3.10 Understanding Range
The advertised range of up to 25 miles is achieved under ideal conditions, such as flat, open terrain with a clear line of sight and no obstructions. In real-world scenarios, the effective range can be significantly shorter due to various factors:
- Urban Environments: Buildings and other structures can reduce the range to approximately 0.5 to 1.5 miles.
- Forested or Hilly Areas: Dense foliage and uneven terrain can further limit the range, often to less than a mile.
- Аба ырайы шарттары: Atmospheric conditions can impact signal propagation.
