If a 1.7 dBi antenna connected to a 26 dB booster (max. uplink power 446 mW) improves my signal strength from -75 dBm to about -60 dBm, then would a 5.2 dBi directional antenna (pointed in the ideal direction) give me much of an added benefit? Not sure if there is math that can convert between these units or if it's apples and oranges xD
