    For that distance a directional YAGI-type antenna would probably be the best, especially if all of the signals that you want are broadcast from the same location. A large omni-directional antenna like the CM 4228 also might work at that distance.

    Anyone have any experience with the Eagle Aspen DTV2BUHF? Looks like a DB-2 clone.

    CM4228 is not omnidirectional, it is highly directional bow-tie array.
    Anyway, excellent choice.

    Thanks Tom,

    I know the direction of Mt. Wilson and hope to get the LA stations, which I prefer. I thought KGTV was HD too. I know KNSD is not. All LA is. If it weren't for ESPN and HBO, I would have no need to subscribe to DirecTV. There is so much free being broadcast near my house.

    I think I read in a post that once the major broadcast stations have fully complied and gone completely digital thay will abandon their UHF frequencies and revert to VHF. Then the market for "HD" VHF antennas will blossom.

    I'm in Central NJ and am in the NY DMA (but might be able to get some Philly stations as well). Anyway, I would prefer to use indoor antenna if possible, and essentially, the only channels I am looking for are WPIX, WWOR, and PBS HD, as the others come in through D*. So my questions are:

    1) Are the HD versions of these channels VHF or UHF?
    2) Where could I find a listing of all HD channels in my area, including the subchannels available?
    3) What indoor antenna would suit my needs, if any?

    They have the option of retaining their old assignments or keeping the new ones. It is very had to tell at this point where they are going to end up. If putting up an antenna now (a good one), I would make sure I could cover VHF as well as UHF. For a temporary situation (if my locals were on UHF now), I would put up an inexpensive UHF antenna.

    99.9% of the stations have basically decided what channel they will be on after 2009. Look at this web site http://hraunfoss.fcc.gov/edocs_public/attachmatch/DA-06-1082A2.pdf

    Virtually the only ones still in doubt are stations who selected VHF-lo, channels 2-6. . The FCC has given them the opportunity to change those elections (like"please don't use VHF-lo"??).

    yeah...and one of our locals in that group, channel 5...I sure hope the don't revert, because there is a very severe power restriction on VHF-LO by the FCC...their analog signal sucks and I'm only 27 miles from their 2200 ft towers!!! Right now they are using Ch 59, and have a reasonable signal.

    Thanks for the site...I'll see if any of the other locals are going to revert or stay.

    Damn! It looks like nearly all of them are going back to VHF if I read the chart correctly, incuding WOI on Ch 5.

    What I'm interested in are :

    Des Moines, IA

    KCCI, Tentative: 8
    KDIN, Tentative: 11
    KDSM, Tentative: 16
    WHO, Tentatie: 13

    Ames, IA

    WOI, Tentative: 5
    KPWB, Tentative: 23
    KDMI, Tentative: 31

    If I'm interpreting these correctly, 5, 8,11,13 will all be going off UHF (their current assignments) and back to VHF. Farkle!!!

    What is the date for the change over?

    I would not classify the CM 4221 or 4228 as highly directional. When I bought my 4221 in 2001, before CM was acquired by Andrews, they had much more data on their website about their antennas, and if remember correctly, it was classified as a multi-directional antenna. A bow tie array antenna by design is multi-directional, because it has such a large reception area, as opposed to an "arrow"-type Yagi antenna which IS highly directional, but has a very small, but concentrated reception area.

    I'm able to point my 4221 at a point in between two broadcasting locations and still get both of them. When I was using a Silver Sensor antenna, a Yagi-type antenna, I was never able to do that. I wouldn't have bought the 4221 at the time if it wasn't multi-directional, since in my area, the local stations are broadcast from three different locations. If you can find some data that confirms your belief, I'd love to see it.

    all i did was take a piece of co-ax cable, stripped the last 2 feet of it down to the center wire, plug the other end into the box. Stick it on the wall, and I get all but one HD channel. If i point it right, I will get the last one. I live 30 miles from Cleveland btw. I learned this trick from some tech guy.

    All locals in San Diego are broadcasting a digital signal and have been for over a year. KNSD, KPBS and KSWB all broadcast in HD from Mt. San Miguel in Spring Valley, but I've never been able to get KNSD. KGTV and KFMB both broadcast from Mt. Soledad in HD and Fox broadcasts in HD from Mt. San Antonio in Mexico. I'm not sure where KUSI broadcasts from, they are broadcasting a digital signal, but not in HD.

    For #1 & #2, check out the FCC TV Query Database. This is the definitive source for all possible information on broadcast channels in any area that you want. To point your antenna correctly, you can use the Census Bureau's Tiger Web Server to get the GPS coordinates of a broadcast location and then check out the distance and angle from your location using indio.com's Distance Calculator. That info and a compass should do the trick.

    For #3 check out antennaweb.org.

    The CM4221 has a beamwidth of about 45 degrees, the CM4228 about 15 degrees. Yagis of the same performance have much narrower beamwidths, but even the CM4221 is not particularly multidirectional. Note that these bowtie antennas alo have some pickup from the rear of the antenna.

    Your interpretation is correct. It's possible 5 may decide to go UHF, we shall see. But the others will be VHF-hi. The good news is that you need a much smaller antenna for VHF-hi than VHF-lo. Also some UHF antennas (CM4228, 91XG) have decent VHF-hi performance so if your VHF stations are close you can use one of these antennas.

    I was using my personal experience of tuning with the Silver Sensors. If I turn it away from the direction of the towers, the signal will keep getting lower and will eventually be 0%. The same thing has happened when I've setup the Silver Sensor in 2 other houses. :flag:

    I tried this with some extra cable I had laying around and pointed that sum bitch out the window. It pulled in all the relevant channels at or near 100% signal strength. It even works better for me than the rabbit ears/loop and amplified antennas that I bought (rented) from radio shack.

    Keep chopping wood baby!:D

    As crazy as some make think it sounds, out of curiousity i tried the same and pulled in 3 of my locals (cbs, nbc, abc) with a signal strength of 60-75% and i am 38-40 miles from the towers. :D
