A minor correction: 3 db is twice power, not 1 db.
The formula is: db = 10 log(P2 / P1) = 20 log (v2 / v1) where P is
power and v is voltage.
12 db is an increase in power of about 15.8.

SolidSignal.com has good info. Note new Channel Master model 4228HD
covers down to channel 7. Channel Master 4228 has the highest gain of 12
db. Remember that 1 db = a doubling of power so 12 db is a lot.
