I'm a bit confused. Are you saying that the SWR when hooked up to the amp is different than when hooked up directly to the antenna? if that is the case it is because the input impedance of the amp is different than the antenna impedance. You would see this if the meter is between the radio and the amp. If the meter is after the amp it is because the amp has harmonics and the meter cannot tell the difference between the fundamental frequency and the harmonics.
