Enter details and press calculate: Card Power (dBm): Cable length (ft): Antenna gain (dBm):

Cable +Card -Cable -Conn. +Ant. Total: LMR-600 -1db = LMR-400 -1db = RG-213 -1db = RG-58 -1db =

Note: Connector insertion loss is generally 0.15dBm. Coax ratings are to manufacturer specification which we have found to be much higher than measured.

Transmit Power:
Step 1: Calculate Loss: Loss = (length in feet x cable attenuation) ÷ 100
Step 2: Calculate Loss Total = (Loss x 10) ÷ 10
Step 3: Calculate Totals : Transmit Power = Card Gain + Antenna Gain - Loss Total - 1
