let's say your unity gain is 20dbmv & your tap value is 17bd, 4 port. if you hook up your modem at the tap, you should be transmitting at 37 or +- 3 db. if not then you might be not align right on actives, or might need to reoptimize the node. oh yeah, add your unity gain to your tap value, thats how i got 37.
thanks....
