Feed line loss

Hi All,



I am reading a chart of cable loss for RG-8x and it says it has a loss of 8.6db per 100ft on 440MHz. So.. let's round it to 9db which is aproximately 8x. Does this mean it only lets 0.625W of power to the antenna (for a 100ft of cable of course) if my HT outputs 5W? I am a bit confused...



Thanks!
