There seems to me some wonderful and creative

Some of the main channels are very fussy about the

the junk channels would probably be OK using old

<div>I bought an amplified splitter off eBay. I have a 2-way
passive splitter at the ingress, with one cable going to
the modem and the other the amplified splitter. From there
all my runs go direct to their respective devices,
including my HDHR prime. It works quite well for my home
setup. When I get home I can post the manufacturer and
model of the splitter, if anybody cares.<br>
<br>
In a perfect world the only cables going to my TVs would
be Ethernet, but the tech isn't quite there yet, and with
my penchant for watching live TV combined with the
copy-protection flag crap that so many channels use, it
may never happen.<br>

<div>Putting the amp at "the ingress" is the safest place to put
one... using it further down the line, after having already
reduced the signal with splitters and long cable runs, will
often result in reduced signal QUALITY, which is far more
important than signal strength. Obviously if your signal
coming in is very strong to begin with, you may get away with
it, but typically the cable companies only put out a signal
strong enough to go through 7-10 dB worth of loss, which will
occur with a 4 way split and a long cable run. Amplifying the
signal after a 7dB drop will likely result in a high strength
but poor quality signal... at least in my experience.</div>

Looking at my existing InfiniTV PCIe, the signal strength for all
four tuners varies from about -4 dBmV to -5 dBmV while idle, and
around -2 to -3 dBmV while playing a channel with right around 35 dB
signal to noise level. Is that good? Bad? Indifferent? Am I
likely to run into any problems if I split it two, possibly three
ways?<br>
