Oh mistress of the airwaves thou hast done good once again

but granteth us yet one (or more) boon or boons

which out of
this this and
this is most bestest
should I be looking at high Db or low Db?
and.... more money = betterer?
and..... (I'm going for group discounts on boons here

) will it work just as well boosting one signal then splitting it or go for one input and 6 boosted sig a nails?
