i dont know if they are wanting to push more of the professional installs now, but everytime we call one in, one of the first things they ask from us is our SBCA cert. numbers...
and just my opinion, but i kinda do wish they would require professional installation on most stuff, if i was E* or D* i would, for one for warranty reasons...
and i know, there are probably customers out there that could do the job better than some of the "professionals" out there...
but you would be surprised how many service calls i go on, where some guy and his buddy spent the weekend installin the system, only to find out they can't get it working (because for some strange reason, they can't use their ancient RG59 into a 8 way splitter to run 3 recievers.. that was my last job today
) then they expect me to come out and fix it for free...
if you are wanting to do the self install so that it looks right, or that it's mounted right, or whatever, just get involved...
before the guy gets there figure out where you want it, heck, get a compass out and see if it's gonna work there
then, if you are worried about wire, run the wire yourself, just make sure you use decent wire...
sorry, i'll stop ranting now,
just my 2 cents
