This is why I feel it's good to walk thru with the homeowner and try to have them envision every possible gadget they might have in a particular room. It's a tough call, but I've found that more is better sometimes. For example,with the advent of digital tv in our area,I always pull a phone with every coax.Cat 5 is a standard with me these days,and quadshield rg6.And no looping,everything is a homerun.If there's an entertainment center,I'll put at least one 2g for receps and sometimes 2. Same for a computer location. Still hard to think of everything though. Russell
