Goodbye Dish. Hello OTA. Antenna recommendation please.
Hi. After 12 years of Dish Network we've decided to cancel and go OTA. Going to build a budget HTPC and use the hdhomerun tuner. I've had a few friends build the homemade DB4 antenna that's all over the web, but after some reading, I see it's only UHF. I think I'm likely going to need a decent sized outdoor antenna on my roof. Here is a copy of my tvfool report:

Hello and welcome!

The good news is that your signal strengths are good and all of the major transmitters are clustered together west of your location. This will make it easier to get all the channels with a straightforward antenna setup. Quote:
Since all of your channels fall within the range of channels 7 thru 69, your situation is perfect for the Antennacraft HBU-22, 33, 44, or 55 family of antennas, or the Winegard HD7694P, HD7695P, HD7696P, HD7697P, or HD7698P family of antennas. These are all specifically designed to handle the limited channel range of 7-69 (helps make the antenna a little smaller) and range from small to large sizes depending on the strength of your signals. For your situation, I'd recommend either the Winegard HD7696P or the Antennacraft HBU-44. Under ordinary circumstances, your signal strengths are good enough such that you could use a smaller antenna. However, since you mentioned the possibility of dense tree blockage, I'm recommending these slightly larger versions of the antennas. The larger you go, the more margin for error you will have to deal with the unknown variables in the environment. Install the antenna on the roof and point it at a compass heading of about 282 degrees and you'll be set. |
Thanks for the response. A couple more questions if you don't mind. There is a switch on my roof that distributed my Dish with an RG6 cable going to every bedroom and living room. Can I use a good quality splitter to distribute the antenna to all of those rooms. Would I need some kind of amplifier? Can I use my old Dish mount and extend a pole from to mount the new antenna when I remove the old dish, it's just a standard mount like this:
http://i48.tinypic.com/2wq7cax.png I'd like to get the antenna up a few feet higher from the top of the roof. Thanks again for you help. This antenna stuff is so new to me, I've had Dish for the past 12 years, and DirecTV a few years before that. |

If you're going to split the signal many ways and/or have long coax runs, then it is a good idea to include some kind of amp early in the chain (before the signal has a chance to degrade by much). Mast-mounted pre-amps usually work best because they are usually designed with very low Noise Figures (internally, self-generated noise) and can be placed as early in the chain as possible (right after the antenna). Indoor "distribution amps" will also work. Once the signal has been amplified, the coax length and splitters will not have much affect on your signal any more. The only caveat with amps is that you must watch out for overload. If the input signals are too strong, the amp will start distorting the signal rather than providing a clean amplification, and this can make things worse rather than better. For your particular situation, I think you are safe. None of your signals are strong enough to create concern for amp overload. "Good" amps will have a Noise Figure spec of 3 dB or less. Some good quality pre-amps include the Channel Master 7777, Winegard 8275, or Antennacraft 10G202. Quote:

Great info, thanks for everything.
If I wanted to get a stronger antenna, like the Winegard 8200U, would I be able to do the split to the 3 bedrooms and the living room without a preamp? It looks like it'd cost almost the same to buy the 8200U as it would to buy the HD7696P and the preamp, plus I might even pick up some Tulsa stations, it looks like I'm in the violet zone for Tulsa using the KMZ file for Google Earth. Thanks |

The HD7698P (the largest of the HD769xP series) is also 14 feet long, but only about 4.5 feet wide. It has about the same performance as the 8200U except that it only covers channels 7-69. It doesn't actually do anything to save money, but it can improve the weight, size, and wind loading considerations for your mount. If you only care about the Oklahoma City stations, then you probably don't even need to go that big. An HD7697P is probably big enough for stations this close. Also, FYI, splitters are usually built in even powers of 2 (i.e., 2, 4, or 8) because that helps keep the power distribution balanced. Even 3-way splitters are usually 4-way splitters internally with one extra path capped off. If you do end up using a splitter with more outputs than you need, please remember to terminate the unused ports (inexpensive F-type terminator caps are available for this). This prevents any extra signal from being reflected back into the coax and creating the potential for self-interference. Quote:
Sometimes it's nice to get programming from multiple metros (maybe different local news, weather, community programming, and sports), but you will also notice a lot of duplicate programming. A lot of the major network programming will simply be redundant. You have to ask yourself whether the added programming is worth the added expense/complexity of having a multi-metro antenna setup. |
I found this Antennacraft model (CCS1843) at Solidsignal, seems to be comparable to the Winegard 8200U, do you know anything about it? It's quite a bit cheaper and if it'll pick up the same as the 8200U, I think I'll go that route. It's big, 15' length.

These few dB of difference won't mean anything for the Oklahoma City stations since they are so close. If you are going to install an antenna rotator for the Tulsa stations, then the extra few dB will help. Those stations are starting out with negative Noise Margin values, so every dB will help. A good pre-amp is also important when going for stations at this level. |
