Way off topic: HDTV

I have some fundamental beliefs. One is that one should not have to pay for TV that is filled with commercials. Therefore, I have never had cable nor have I subscribed to any other form of TV content. I do however spend a lot of time playing with antennae and learning all I can about TV transmission. Since the changeover to digital, I have been fascinated with the incredibly high quality of over the air TV. It might interest you that most TV content providers compress most of their signals so they can give you LOTS of channels. In doing so, you lose definition—receiving with an antenna you get the full broadcast signal and truly high definition. When PBS first started broadcasting HDTV from Mars Hill a few years ago, I started experimenting. I spent a bit of money on gear, but I was able to get full screen beautiful high definition digital. Now, I am able to get High Definition digital CBC, CTV, Global, WAGM (and two sub-channels) and PBS (with two sub channels) with the antennae on my roof. Yes, no monthly payment. You may want more, but I don't. :-)
To make life easier when changing around antennae, rather than climb onto the roof—not a good idea for 69 year old men—I have rigged up my TV tower on a swivel so that I can lower it to work on it at ground level. If you are interested in seeing it in action, go to:

So, with a modern TV and this:

Now, back to installing the garage door opener.
