Do I need an amp? in Comcast Cable TV http://www.dslreports.com/forum/r22737959 en Wed, 10 Feb 2010 02:06:06 EDT Wed, 10 Feb 2010 02:06:06 EDT Re: Do I need an amp? http://www.dslreports.com/forum/remark,22745213 neufuse : well took off the amp just to see what signals I get after the 8way amp... here it is

channel 2 0db
channel 47 0db
channel 111 -2db
channel 120 -4db

so looks pretty good, no idea why they had an amp on with signals like that without it]]> http://www.dslreports.com/forum/remark,22745213 Tue, 21 Jul 2009 20:02:31 EDT Re: Do I need an amp? http://www.dslreports.com/forum/remark,22742090 neufuse : I mean an antennuator after the amp not with no amp :P]]> http://www.dslreports.com/forum/remark,22742090 Tue, 21 Jul 2009 10:54:47 EDT Re: Do I need an amp? http://www.dslreports.com/forum/remark,22741325 beachintech :

in the even the signal is lower then expected, where can I get a good attenuator?
attenuator would make the signal even worse ;) Take the amp out. You should be fine.

If they drop into negative territory by more than -3dB, I'd reinstall the amp and install a few attenuators on the boxes. ]]> http://www.dslreports.com/forum/remark,22738646 Mon, 20 Jul 2009 17:37:33 EDT Re: Do I need an amp? http://www.dslreports.com/forum/remark,22738526 joe40 :

yes, I have 8 lines going through the house...

but why would I need the amp if the signal is that high on the boxes after the amp? I thought closer to zero the better? if its +11db on the box wouldnt the amp be over amplifing the signal? because
if you have 15 at the cable box you can remove the amp.
but recheck the cable box signals you will be dropping by 15db
but a fear it may be more.]]> http://www.dslreports.com/forum/remark,22738526 Mon, 20 Jul 2009 17:16:43 EDT Re: Do I need an amp? http://www.dslreports.com/forum/remark,22738293 neufuse : yes, 2 way amp... its a 1GHz amp also]]> http://www.dslreports.com/forum/remark,22738293 Mon, 20 Jul 2009 16:38:19 EDT Re: Do I need an amp? http://www.dslreports.com/forum/remark,22738290 neufuse : yes, I have 8 lines going through the house...

if not then yes you can remove the amp]]> http://www.dslreports.com/forum/remark,22738265 Mon, 20 Jul 2009 16:32:56 EDT Re: Do I need an amp? http://www.dslreports.com/forum/remark,22738226 nthach : I think a attenuator is in need, is the amp installed a 2-way amp? ]]> http://www.dslreports.com/forum/remark,22738226 Mon, 20 Jul 2009 16:27:51 EDT Do I need an amp? http://www.dslreports.com/forum/remark,22737959 neufuse : I'm hoping not... the house I bought had an amp on the line, but the drop signal is high already... here is my setup.....

Drop to 3 way balanced splitter.... 1 to eMTA 1 to SB6120 and 1 to the amp... the amp is +15db... the power at the cable modem off the 3 way right now is +7db...

the amp then goes into an 8way splitter... on our SA 4250HDC (think thats the model) box it is saying the power is +11 db for one but then on the other side of the info screen there is a +15db in orange (warrning color) for the digital recieve? i forget i need to have the box infront of me... i think the 8 way splitter is -10db per port (its an atronix 8way)... I think I dont need the amp... anyone else see any reason to keep it on the line? or just drop it?]]> http://www.dslreports.com/forum/remark,22737959 Mon, 20 Jul 2009 15:43:10 EDT
