No,  not even close. I don't remember if there's a  formula or chart but I'm
pretty sure one or the other. An SWR of 1.5 with a 100 watt output would
only yield a few watts of reflected watts, I'm sure less than 10.

Hi all:

If a load of 100W is input into an antenna, you receive an SWR reading of
1.5, does this mean that you have 50W of reflected power?
IF this is the case, how can modern rigs operate with 2 to 1 SWRs, unless
the finals can safely dissipate 2 or 3 times the power then suggested
ratings?
