Hi Lance: Only seen this once before, but i normally don't bother with aerials.
If the magmount has a rubber boot fitted, take it off. also check that where the whip screws in you have nice shiny threads for contact. You may also have to increase your earthing to the antennae.

Did you recalibrate the meter after increasing the power?
