See <http://www.repeater-builder.com/tech-info/db.html> From that table 1.5 is 29.2%, so 150 times 0.292 = 43.8 150 less 43.8=106.2 watts A few numbers worth remembering: 1db is about 20% 1.5db is about 30% (actually 30% is halfway between 1.5 and 1.6) 3db is about 50% 6db is about 75% 10db is 90% 20db is about 99% All of the above numbers are close enough for field work, especially when you factor in feedline and connector loss. And 3db is double the power 10db is 10 times the power 20db is 100 times the power. The big think is that you hear the Yahoo!
