your not going to lose 19 db using 2 splitters .....sounds like you have an issue somewhere else....test the signal at the ground block and at the tap.....and screw their homerun crap ive cascaded splitters hundreds of times without issues....the theory is if a piece of cable goes bad in the loop system the whole system goes out like a string of xmas lights with a bulb out......but in reality if the homerun goes bad or the drop goes bad you have the same issue in a homerun system.....and bottom line the cheapo's will probally pay you 10 bucks to run a outlet or even worse the outlet will be included in the install and you wont get paid for crawling in your belly in a hot attic thru insulation to route an outlet.....do yourself a favor and gey out of this business before you get into it
