we only have freeview works great in lounge, but I am going to put an aerial in the loft for the bedrooms, I hate see lots of aerials on roof, dies the higher the Db gain on a booster mean you get a signal, can anyone explain this better, Ive seen a 42Db gain booster.

Db Boosters are fine,But can sometime cause Interference and noise in the Picture!
It's Called Cross-Channel-Interference!When You boost a Signal and it appears on other channels as a faded Ghost in the background!
Go for one that has an Amplifier built in-So you can adjust the gain manually!

VERY important in case you think approximately DECIBELS to be LOGARITHMIC.....10 to the 0 skill is ONE. 10 to the 1st is TEN, Ten to the 2d is a hundred..... 3 db DOUBLES the skill like Pete suggested.... 6 db Quadruples the skill.... so as that a million or 2 selection earnings could make a real distinction.... WHY do they use DECIBELS? undemanding, that's undemanding to function or subtract....once you Do each and all of the mathematics on an in depth antenna array that's basically much less complicated for an engineer to apply.... and you earnings too....you need to purchase all your antenna equipment basically via finding for the optimal +Db on each and each piece you utilize...Or the backside (- db) on each and each piece... I run + 20 db warm..... and step it down with a - 6 db attenuator at each and each container. image is RAZOR SHARP and no noise!
