6.0 Installation 6.1 Path Calculation Assuming adequate antenna heights, a basic formula to determine if an adequate radio signal path exists (i.e. there is a reasonable fade margin to ensure reliability) is: Fade Margin = System Gain - Path Loss FCC regulations where all values are expressed in dB.

A multipath environment is where the signal from origin to destination may not have a direct path as seen in the illustration below: In a multipath rich conditions is it recommended that each pMDDL5824 end have a pair (2) of omni directional antennas that have at least half-wavelength distance between them. A set of (4) Omni-directional antennas is good for a pair of pMDDL5824 radios.

Question: How do I reset my modem to factory default settings? Answer: If you are logged into the pMDDL5824 navigate to the System > Maintenance Tab. If you cannot log in, power on the pMDDL5824 and wait until the modem complete the boot up process. Press and hold the Config button for 8 seconds to reset to a factory default Master.
