Antennaweb tends to be ultra-conservative with their estimates. It's not a bad site, but IMHO, there are better ones. TV FOOL http://tvfool.com/ and RabbitEars http://www.rabbitears.info/search.php are better sites for estimating available signals. TV FOOL ocassionally gets an older FCC permit thrown in or something, and a station shows up with the wrong RF channel or different broadcasting location.

I bet you have the "old" model 4228. It was the Cadillac of 8-bays. The new, "HD" model has some issues (see link below). The phasing issues can be corrected, but why should a person have to fix a new antenna?
48 feet + a coulple of feet above the top of the tower is a great start. A distribution amplifier is usually the way to go when splitting the signal, provided that you don't over amplify a strong local signal. Distribution amps are available with various gain levels, as are pre-amplifiers. Be careful using both a pre-amp and a distribution amp. Occasionally you can introduce more "noise" and cause more problems in some situations. Use terminators on any unused terminals on all splitters and amps. Use RG-6 or RG-6 quad shield cable.
There are still Lo-VHF, Hi-VHF, and UHF channels broadcasting. Use TV FOOL or RabbitEars (links above) to find your stations. You need to know the RF channels not the virtual channels to find out what type of antenna you need.
The FCC is currently (and quietly) trying to eliminate another 120+ mHz from UHF television for the prez's National Broadband plan. They got a good start with their $200+ million dollar broadband map that, based on some other internet forums, isn't even accurate.
They are trying to make this look voluntary, but it seems to be a surrender now or be shot later situation. LPTV could possibly be forced from the air in many areas. Even if you don't have VHF channels today, the odds are quite good that within 5 years you will have some if Congress approves voluntary spectrum auctions. None of this is set in stone, but the rock is there and there are men with chisels at the ready.
The above, sadly, is also something to consider when pruchasing an antenna if you plan on it lasting longer than 5 years.

Today's Featured Article - Earthmaster Project Progress Just a little update on my Earthmaster......it's back from the dead! I pulled the head, and soaked the stuck valves with mystery oil overnight, re-installed the head, and bingo, the compression returned. But alas, my carb foiled me again, it would fire a second then flood out. After numerous dead ends for a replacement carb, I went to work fixing mine.I soldered new floats on the float arm, they came from an old motorcycle carb, replaced the packing on the throttle shaft with o-rings, cut new ga
