For those that go through the gamut of DTV installs, what is the deal with the ever changing *approved* fittings. One of the things that has always irked me, is that in the past, whenever I required a onsite DTV troubleshooting....and it has been almost 3 years since I needed one, I clearly remember the 4 visits in which every tech by default wanted and did cut the coax connector and put a new one in ---- making the cable run shorter on both the receiver and *av closet* side shorter each time. Same goes for when they went to the roof. Let's troubleshoot by not really doing much by changing the connectors. I'm curious. So now that the current approved connector is not PPC EX6L but I believe it's SNS - when you walk into a site that has PPC EX6XL, does *the book* call for you to change it to the new ~approved~ connector ?
