I'm still not grasping it though....if the yellow brick don't have an active return gain then there isn't nothing to worry about with in the property i'm not sending back 60 db to them etc.......if it's increasing the signal to the modem and the other devices and making them work a treat after boosting the incoming signal then all I'm doing is actually getting false readings, well not false but readings from equipment within here after the signal has been boosted...........so it's not like i am actually getting them from the external feed with massive spikes and stuff ....if you get me......
if i went and read my readings at the main point of entry they'd still be showing me sensible levels....it's just after the booster that the equipment is connected too that's showing massive signal levels increased......but as i say at the main feed i'm still getting the norm ?
hope you understand what I'm thinking...
what are you useing to test the point of entry cable m8 ???????
as far as i know the upstream SNR can only be sensed at the headend
why worry if everything is working ok,?????????might be diffrent if your modem was disconecting every now and again
