You have increased the output power by 10 dB. The signal intensity has:

Explanation:
Decibels express ratios on a logarithmic scale, and power ratios relate to decibels by P2/P1 = 10^(ΔdB/10). An increase of 10 dB means P2/P1 = 10^(10/10) = 10, so the signal intensity increases by a factor of ten. Doubling or quadrupling correspond to about 3 dB and 6 dB, respectively, not 10 dB.
