Aynone know anything about Antenna television?
MonMotha:
In general, you run a "link budget" for each run. You can add up the dB loss from each split (it's almost always listed on the splitter, and sometimes not all ports are the same, which you can use to your advantage when doing multiple splits) and you try to make it about the same on each run. Then get an amp at your antenna, if needed, and adjust it so that all your tuners are happy.
Mind you, the cable is also lossy, but if they're all "about the same length", it evens out.
If it's unavoidable to have very uneven path losses, you may end up overloading the receiver front end on some in order to get a strong enough signal for the others. This is worse in the US, and especially in cities, due to multipath. European DVB uses a different modulation scheme that doesn't cover as big of an area, but it resists multipath. If you have that problem, you can just drop an attenuator right in front of the hookup to the TV experiencing the overload.

For you guys using WMC to record TV and XBOX360s as extenders, have you had any problems with it all of a sudden getting disconnected from the Media Center PC? Or is there things to do to optimize the connection between Windows 7 Media Center PC and XBox? I watch a show for a little while and then it will just drop and I'll have to reconnect. I have both the media center PC and XBox360 wired to a 100mbit switch. I have tried googling, but no luck so far. It works well sometimes and then sometimes it will keep dropping every couple of minutes. I'm not doing too much else on the network (other computers/phones are off, not playing any online games, surfing the net, etc.)

I had disconnects when I first set mine up and it was the xbox at fault. Once I took it out of the system I've had solid connections for the past 6 months or so.
In your case it could be the xbox, switch, or PC causing the disconnects. I'd try watching video streamed from the internet to the xbox and PC to see if you can isolate the problem.

It must be the Xbox, because PC works fine. So do you not have any extenders now? Or what do you mean by taking the xbox out of the system? All the video I'm watching is on my local network (XBox media extender watching videos from Windows 7 Media Center PC).

Oddly, my little converter boxes do a MUCH better job pulling in marginal signals (mostly contaminated with multipath rather than a pure SNR issue) than the built in tuner on my Samsung plasma. Now, the output of the box isn't HD, but it often works flawlessly when the Samsung just plain gives up. Apparently the box I have (the old coupon eligible one from Fry's) is well known for having a surprisingly good ATSC demod while Samsung uses crap stuff.
Now, the old PCI ATSC tuner card I got back in ~2004...that thing needs a darn near perfect signal to work properly.
