WebSubtracting 3dB (actually 3.01) from any dB value halves the power (ratio). Adding 10dB to any dB value multiplies the power (ratio) by 10. Subtracting 10dB to any dB value divides the power (ratio) by 10. Changing the sign of a dB value inverts the power (ratio). Adding 1dB to any dB value multiplies the power (ratio) by 5/4 (actually 1.26). http://www.flexautomotive.net/flexcalc/VSWR2/VSWR.aspx
