Preparations
In order to obtain the best performance of booster and system, user must calculate
the transmission power to meet the booster technical requirement and FCC regulations.
Please follow the calculation below:
1. Convert power of the radio device from milliwatt to dBm.

NOTE:
dBm = 10 * Log (milliwatt)
2. Estimate the attenuation of cable (please refer to manufacturer’s specifica-
tions)

NOTE:
It is suggested that the cable loss between booster and DC
injector should not exceed 10 dBm.
General Cable Attenuation List
LMR400 LMR600 LMR900
dB loss per meter 0.221 0.144 0.098
Suggested max. cable length (m) 45.24 69.44 102.04
3. Calculate the actual power of booster in the pole as follow:
Radio Device Power (dBm) – Cable Loss (dBm) – Misc. Loss = Input Signal
Level (dBm)
