It's a common misconception that chaining boosters will help - in general it won't, because if you have that weak a signal, your boosters will amplify the noise and you'll end up with plenty of signal but with a crap signal/noise ratio (snr). snr is probably more important than signal strength !

Actually the whole art of RF cables is pure magic.
For example having a tee (whether used, terminated or not) will drop your signal strength by half (3dB). Likewise (not obvious) the above about 2 boosters. 
I’ve found that even professional antenna installers need toilet paper to wipe their mouths.
You *need* to have your antenna installed by someone who understands the magic (good luck in finding one)
