Update May 2015: this antenna was built in 2009. It is now 2015. We still have it and it's still doing it's job. I've since put an amplifier on the mast and we now can get that fringe channel lightly to the left of the others without any longer having to use the rotor to turn it. Actually, I leave it set facing the fringe channel and the stronger ones are the ones that compensate. I go up on the roof to check things every couple of years and so far all is well. I would recommend stainless hardware throughout if doing this. My plated stuff is doing well but stainless would have given many, many years of carefree use. Oh, I also now have a 60" Sony Bravia LED instead of the old Sony analog TV we had at the time of the original construction.
We've had Cable TV and Cable Internet. It seems that there is less and less on cable than there ever was. Cable in my area is $49. I eventually cut down to basic for $20 and supplemented with Netflix. Netflix is excellent by the way but that's another story. We also have my macintosh connected to the TV so we can Hulu any program that played recently.
I'm finding that even basic cable has little 'value'. By value I mean I get the basic local channels and a bunch of junk otherwise. The channels I look at I could get for free if I used an antenna. Hence, I've decided to minimize.
Here in Southern Maine the TV stations are mostly in Portland about 30 miles away. Some are further, about 50-60 miles away. Most HDTV antennas work for 30 miles and a few claim to get up to 60 miles. I decided that I need more antenna than that. Something where 60 miles might be the limit but a doable and good limit. I've decided to produce a DB8. A DB8 antenna has 8 receiving elements, or 4 pairs of elements. It's basically two DB4 antenna's combined. The last picture in the segment is a commercial one.
What follows is my foray into the world of HDTV antenna construction and trying to squeak the most out of it for a moderately fringe TV area I live in.
BTW, the last segment contains all kinds of HDTV signal information and links to places to assist you in learning more. I was a teacher for 30 years (no I don't want any help with my grammar, I said I used to be a teacher) My job was simplification and clarity. I hope this instrucatble is up to that.
