Whole house antenna

Hello,
I am looking to drop or at least cut back my DTV service bill is ($205 per month) and am wondering if putting an antenna in my attic would supply the 8 TV's i have in the house. All TV's are new and have tuners I also run apple tv on two of them and all have CAT5e cables with internet available. My question is can I put an antenna in the attic and split it to all 8 TV's would i need a signal amp? the antenna would be about 23' above ground and the longest cable run would be about 80'.

Thanks,
Steve

Nice TV fool report, lots of stations. You have a mix of VHF (2-13) and UHF (13-51). You have a few VHF-lo channels, but they aren't important, so I would ignore them. Channel 3 will be MeTV, and real channels 2,4, and 6 are religious, spanish, and not broadcasting, in that order. My biggest concern is that if we put an amp on the system to feed 8 TV sets, the strongest signals (channel 18, for example) may overload the system.

Next questions:
1. Do you have a spot where you can get a clear shot at 164 degrees?
2. Is there any metal in the attic (ductwork, vapor barriers, etc) that may interfere with reception?

I would go at this by first selecting an antenna and installing it in the attic to just ONE TV. Then I would add the splitter and add ONE TV at a time and see what happens. You may have to put an amp somewhere, but with those strong signals, you may not need or even want one.

We have a lot of antenna experts here who will each have their own suggestions, we'll sort through them and recommend an antenna for you. Right now I'm kind of leaning towards a Stellar Labs Part #: 30-2440 Stellar Labs VHF/UHF HDTV 60 Mile Fringe Yagi Antenna | 30-2440 (302440) | Stellar Labs

Yes I have a clear shot to 164 and no ducts or metal I can also mount on roof up to 35'

Put it outside if you can. I always recommend outdoor mounting whenever possible.

I was hoping another one of our experts would have weighed in and given their thoughts by now...

It's difficult to add to what MrPogi has already said. Any true high VHF/UHF antenna should work if signal levels are as good as what the TV fool prediction shows. As long as there are no blockages in the direction of the major broadcasters any of the Antennacraft HBU line, Winegard HD769xx series, RCA ANT751 should work. I would choose one with more UHF gain then the HBU11,or ANT751. The Stellar Labs 30-2240 should work fine. On the 8 way distribution I would suggest building it out slow testing and trouble shooting as you go checking all cables for continuity and shorts. As strong as your signal levels are predicted to be you might be able to get by with out an amplifier. While I am no expert on building 8 way signal distribution systems. I think I would shy away from using an eight way distribution amplifier for the simple reason that if the amplifier, or power supply goes out you loose everything until the parts are replaced.

I had my system split 8 ways, but that was with much weaker signal and a preamp. My major concern for an amp is the very strong stations. Steve's suggestions for antennas are also good, and agree that the ANT751 and HBU11 probably wouldn't provide enough gain if it is split 8 ways.

Building a system from scratch designed for OTA is good to hear. Using a left over distribution system is often times not optimal for OTA signals, and can be trouble right from the start. Keep coax runs as short as possible. I'm really not the right person to offer much advice on building an eight way distribution system.

Nor am I, because there are so many variables that depend on the length of coax runs (over 150 feet) local VS distant (real) signal strengths and more. That's why you pay the OTA antenna specialist with his Sadelco meter for his time to create a genuine antenna survey for your particular location and make recommendations. Attenuate this ... amplify that ...
