Maximum power will decrease at lower voltages. **The device hops on 50 channels selected, using the CM command, from 101 available frequencies. ***We estimate rural ranges based on a 14.5 km (9 mi) range test with dipole antennas. ****Range estimated assuming that the urban noise floor is approximately 15 dB higher than rural. The actual range depends on the setup and level of interference in your location. ******Range figure estimates are based on free-air terrain with limited sources of interference. Actual range will vary based on transmitting power, orientation of transmitter and receiver, height of transmitting antenna, height of receiving antenna, weather conditions, interference sources in the area, and terrain between receiver and transmitter, including indoor and outdoor structures such as walls, trees, buildings, hills, and mountains.
