Enter one or two frequencies. If Frequency 2 is filled, the page also compares the path loss drop and can auto-balance the power setting between both frequencies.
FSPL + Extra Loss for Frequency 1
-
Enter Frequency 1 to calculate.
FSPL + Extra Loss for Frequency 2
-
Optional. Fill Frequency 2 to compare.
Comparison Gain Drop
-
Shows how much more path loss Frequency 2 has compared with Frequency 1.
Power Balance Calculator
Type a power setting on either side in 0.1 dBm unit. The other side will be cleared and recalculated automatically using the path loss difference.
Balanced Power for Frequency 1
-
Waiting for power input.
Balanced Power for Frequency 2
-
Waiting for power input.
Balance Logic
-
Needs both frequencies to compare.
Formula used:
FSPL (dB) = 32.44 + 20log10(distance in km) + 20log10(frequency in MHz)
Total Loss (dB) = FSPL + Extra Attenuation
Balanced Power 2 = Power 1 - (Loss 2 - Loss 1)
Balanced Power 1 = Power 2 - (Loss 1 - Loss 2)
