My wife and I are building a town home in downtown Dallas. I am having a smurf-tube put in so that I can eventually run a cable to the roof and set up an antenna. We will have rooftop terraces, so accessing the antenna should be easy. We will have at most two screens in the house, but for a long while it will probably be just the one we already have, a barely used 46" Samsung LCD TV. We watch hardly any television at all (frankly we would rather read) but wouldn't mind picking up good stuff from around the world if possible. My wife is Russian - it would be nice to get some Russian channels. I wouldn't mind picking up sophisticated news coverage (BBC, or Al-Jazeera English - something of that level) if possible; would love to see some international soccer, but don't care about watching sports on a regular basis. I don't know the first thing about receivers, antennas, any of the switching or other downstream equipment, providers or channels. Zip. I am good with Macintosh computers, if there's any role for them to play... I have a 10 year old Sony home theater system I bought and am using now in our current home, and I won't mind using it in the new one if possible, but I assume it would only play a role in handling the audio. If anyone starts using acronyms to explain anything, I'll be instantly lost. I am motivated to learn just enough to install and master a simple solution that will get me the above and then I want to forget this stuff and focus on other things. What I would like to know first is there a simple primer I can read that will lay out the basics at the most junior level, so that I can understand what the major issues are? Any recommendations for a basic antenna (that will not have to be moved manually or with a motor) that will give me the local channels in HD as well as international channels? I don't want to spend a fortune, and I don't want ongoing costs or subscriptions to anything. I assume cabling is still coaxial? or has that changed? I am planning to run a piece of RJ-45 alongside the coaxial cable in the smurf tube up to the roof and break it out where it passes inside the attic to connect to a secondary WiFi receiver (probably an Airport base station) that will help us with WiFi when we're on the roof terrace. Will a coaxial cable interfere with ethernet in such close proximity? Thanks!
