    Thanks for all the replies and suggestions.

    One last question:

    Knowing I already have the Stealth Antenna (Channel Master 3010) mounted in my attic, can I add the 4228 and run them both together? The 3010 is directional and the 4228 is multi-directional.

    Would I be doing more harm than good. How would I connect them together?

    That's a great solution. What you have effectively done is destroy the front-to-back ratio, but that is exactly what you want to do. This is also good when angles are not 180 out, but some odd number. The choice of 4228 is important, because you have created a bi-directional antenna system, which will have less multipath rejection overall, but still enough at the strategic angles needed (hopefully). Less-directional antennae will probably be more problematic if combined like this.

    You can also strategically combine. For instance, if one direction has only VHF while the other has only UHF, you can use a V/U combiner very effectively (be sure to ground the two halves of the reflector together to get better VHF performance, or use a V-only antenna in that direction). There are also join-tenna combiners to optimize a particular situation.

    The DB8 is nearly as good as the CM4228, and better if you need low VHF, which the 4228 will not do. It's just more of a monstrosity to mount and install, and more expensive. If you have no channels below 7, the 4228 is a better option all the way around.

    Edit: See my later post, as the DB8 info in this one might be ridiculously unhinged

    um, are you saying DB8 will get in channel 6?

    Went with the Winegard Square Shooter a few years back. Provides much better signal reception than the 4228, at least for my location. And yes it is mounted in the attic.

    I get all the OTA digital signals in the Phila area.

    I had a 4228 mounted on my roof as high as I could get it. I was only about 13 miles from the broadcast antennas. At the time, I was a DirecTV customer and OTA was the only way I could get my local channels. I had very mixed results. Most of the time, I could get 3 of the 4 channels OK with intermittent depixelation. Never did get FOX which I wanted mostly for sports. I also had a rotor so that I had the aiming point directly toward the stations. After reading one of the posts above, I wish I had tried a signal booster.

    I finally bit the bullet and switched to Comcast Cable and now get everything great.

    I think my main problem was that there are a couple of hills in the way. Also a couple of very tall Douglas fir trees. With DirecTV's big HD upgrade coming by the end of the year, I may switch back to DirecTV. However, I DO like Comcast's On Demand service.

    It would seem like I might have said that.

    But guess what? If I did, I was wrong. I think I was confusing the DB8 with another antenna, which I apologize for profusely. A thousand pardons :eek: .

    To help clear up any mess I may have contributed to, let's first define "channel 6". If you have a DT channel that tunes in as "6-1", it may or may not be really on physical channel 6, usually not. It is very important to understand this when choosing an antenna.

    Also, if that channel is really on a UHF channel and designated to return to physical channel 6 after 2-17-09, your UHF antenna may no longer work, but that is unlikely, as few DT channels will move to low-V slots. Still, it's important to figure these things out ahead of time.

    Finally, if you are truly trying to tune in physical VHF channels, an antenna designed for UHF will not get optimum reception for 7-13 (with the exception of the 4228) and will likely have poor reception for 2-6. Since the DB8 is apparently a UHF antenna, that would make my earlier advice very bad indeed if you were to interpret from it that the DB8 would get you channel 6 (again, my apologies).

    If all of that is confusing, check out this very enlightening site:

    http://www.hdtvprimer.com/ANTENNAS/comparing.html

    which will give you the specs on antennae of all kinds. Supposing you really are needing physical channel 6, from the graphs alone you can see at a glance which would be good choices, for instance.

    Bottom line, figure out which physical channels you really want to receive, which will move to different channels in 2009, what direction and distance they are from you, and how the terrain and obstacles are in between them and you (start at antennaweb.org, but take their overly-general recommendations with a grain of salt). Ignore all other channels, as that will just confuse matters and compromise the choice of optimal antenna for the DT reception on the channels that are important to you. Then you can use hdtvprimer to sift out antennae that are not relevant, and choose one from the rest that would work the best for your situation.

    well i knew you were wrong but hated to call the great TS out on it :) I agonized over my antenna choice over 2 years ago and knew in 2009 that philly 6 was going from 64 back to 6 and i'd need a jointenna for a vhf antenna :) I also studied the antenna heights and powers on the FCC site to help in my determination. it was soooo fun

    but now with HR20 the issue is resolved. All recordings for 6 philly will be on that

    yes, I thought you would come back to correct your post!

    If you are looking for just fringe UHF performance, it's generally accepted that the CM4228 and the Antennas Direct 91XG are the two contenders. The 91XG seems to be better at rejecting multipath, it is very directional. The DB-8 is OK also but the other two have the performance edge where it matters (below channel 52, because above 52 is going away in 2009), and the DB-8 is more expensive than the CM4228 for no real advantages.
    None of these three antennas will work for VHF-lo (channel 6 and below), so for those of you unfortunate enough to have a digital station on VHF-lo after 2009, you will need a combo VHF/UHF antenna or a separate VHF antenna just for your VHF-lo channel.
    The CM4228 is pretty good at receiving VHF-hi (7 thru 13) if your stations are reasonably strong (say "red" or better on antennaweb.). The DB-8 and 91XG do not have the same performance.

    When you buy a 4228 does it come with the hardware to mount it in an attic? I'm getting ready to buy one and wondered if I'd need to buy anything else (hardware, etc.).

    my db8 came with the bracket to mount it on a pole. I bought the pole at home depot i think. My guess is 4228 had a bracket too

    this may or may not help but as a temporary test, i used an old broom handle (had a hole in end of it) and put a nail in a rafter and hung the antenna in various places to see where the signal was strongest

    I have a 3021 in the attic, works OK, some stations ~35 miles away. I have multipath problems in wind though.

    I think my problem was with either poor coax cables or an ungrounded splitter. After moving my antenna to a higher point, which was also closer to the entry into the house, and setting up grounding, the signal is perfect.

    Thanks.

    I am in Downtown Decatur... and ABC is pretty much the only reason I have mine on the roof. Everything else comes in with a coat hanger, cept PBS that comes in with a coat hanger... but not the channel master.

    I never get why people with DVR's that depend on antennas put them in the attic. But getting the best signal, you'd don't need to worry about changing seasons and weather conditions.

    There was a time when my roof antenna broke (thanks Direct TV!) where I used this sitting on my mantle and got every single channel.

    I have it in the attic because the 4228 is ugly. I would be the only house in my neighborhood with an external antenna and all my neighbors would be constantly complaining to the association. I would end up explaining over and over that the antenna is staying and there is nothing they can do to make me remove it.

    So far so good this year though. ABC has remained completely watchable and NBC has only had one night were I ended up watching the SD version of My Name is Earl but was able to watch the HD version of ER.

    I have had a CM 4228 and a Radio Shack $25 antenna in my attic.

    The RS antenna seems to like the "sweet spot" I found a little better than the 4228, but it wasn't much difference.

    As you are reading, and will find out, antenna setup is an art, and not a science.

    It took a few weeks of experiment with my outside antenna of different locations and heights and this and that to find the sweet spot.

    I tried the:
    Chimney.
    Eave (opposite side of the chimney).

    I tried a three different heights on the 2 above places.
    2 feet, 5 feet and 10 feet.

    I tried about 5 locations in the attic, which was essentially "sliding the setup" down through the rafters until I found the best spot.

    For me, I got a better situation in the attic, then I then outside the attic.

    However, I've only recently discovered the advantages of a attenuator:
    http://search.solidsignal.com/?i=1&q=attenuator&site=com&u1=q
    into the system.

    What I may (I'm speculating) is when the antenna was on the outside of the house, the signal to TOO strong, and by putting it on the attic, I was basically knocking down the strength enough to it worked well.

    So yeah, even if you get a CM4228, remember it may take some experimentation. Location, height of the pole, and maybe getting an attenuator would be in the equation.

    ..

    But I have the RS $25 UHF only antenna doing the work now. I still have the CM4228, and I"ve asked for a rotator and attenuator for Christmas so I can experiment some more.

    I actually want to have 1 antenna fixed (like the RS is now) and I'm gonna use the 4228 to "hunt out" other signals from neighboring cities.

    I will have a A/B switch on the two antennas in this configuration.

    Generally speaking, one can count on losing up to half of TV signals when the antenna is set up in the attic. Somehow though in many cases attic installations work just fine.
