    Thanks Doug, I can actually almost understand that :D

    But of course, now we need specifics. In theory I should get a strong signal. I'm about 14 miles from the towers. Unfortunately my last HD receiver didn't have a signal meter so I can't give any real numbers. But the reception didn't seem great. I have a relatively short line to the receiver, probabably less than 30 feet. And the antenna itself is a monster, 131" boom and about 110" wide.

    But when I tried to split the signal one time things got worse. And when I tried to buy a cheap Radio Shack amp I basically got nothing. Obviously it introduced more noise to the system.

    Now maybe a better amp would have worked better. But it wasn't the cheapest one they had. But if I ever want to send the signal to more than 1 set I'll have to do something. Now, unless the guy that installed the antenna did a really lousy job, I can't imagine a 30' line would normally introduce much signal loss.

    It could be a multipath issue I suppose. But there are really no large buildings behind the antenna. So the first question I suppose is what would splitting a multipathed signal do? And, if I had a receiver with a strength meter, would I see a strong signal if it's multipathed? And of course, if it is multipathed, I don't think a pre-amp would do much good.

    For one thing, I'd be concerned about the cheap Radio Shack amplifier. ou saw the difference in noise specs on several amplifiers; where did the Radio Shack units fall? 2 of the 3 in that list did worse than if they weren't in line at all. :)

    Do you have any FM towers nearby? Another consideration would be strong FM stations causing your preamp to clip everything because there's too much power coming in over the FM band; some preamps have a switchable FM trap; others require it be added separately.

    If you have any analog stations you can receive near some of the digital channel frequencies, how do those look? Ghosty? Clear? Snowy?

    That antenna has nice clean radiation plots without much rear gain at all. I suppose maybe something off in the direction you're aiming could be reflecting towards you and causing multipath problems.

    If you can get to the antenna to inspect everything, this coul djust be a bad install; maybe a loose wire on the balun or bad coax connector splice, or maybe some elements bent/shorted.

    Do you know if your stations are broadcasting at full power or at some lower, maybe much lower power? Do you know people in your neighborhood who can receive them well?

    Well right now I don't have a pre-amp. And the reason I got it installed was that I can't get up on the roof. It's not that it's very high or even very slanted, I'm just a woos! I had to buy one of those attachments to a leaf blower so I could clean the gutters. So the idea of ME geting up and doing any inspection just isn't going to happen.

    Do I have FM towers nearby? Who knows. This is Chicago, there seem to be towers everywhere. But again, no pre-amp, so I doubt clipping would be an issue.

    As far as analog stations, that's hard to tell. It's been so long since I've actually watched OTA that it's hard to compare. I would say they looked snowy to me, but there was no ghosting. In my mind that would say weak signal without multipathing. But obviously I don't really know.

    I don't know if all the stations are at full power right now. But since all the major networks here are O&O, I would hope (not assume) they are. I know we had major trouble with the CBS stations because they are on channel 3. For the longest time they had to operate at very low power because it was messing up the cable systems in the area until they all moved their default box setting to channel 4. Now they are at full power. But even when they were at 25% that was my most dependable signal.

    I don't know anybody else in the immediate area, but I know a lot of people that have no problem picking up any of the stations from as far away as 40 miles. This would tell me that the power levels at the stations are not the issue.

    So here's the real questions. I just signed up for the $99 HD deal from D*. Part of that deal is the OTA antenna install. Now I know for a fact that the current antenna I have is better than the one they'll give me. But I figure I have about a 50/50 chance of the install being better. It's also possible that the Panasonic receiver just had bad OTA reception and the HDTivo will be much better. The $99 one is only a temp until I get that.

    My initial thoughts are to first hook up the receiver and see what kind of repception I get. If it's OK, obviously the problem is solved. But if it's not, then the fun starts. Ideally I'd like to get the installer reaim and run new cables from my antenna. But I have a feeling that the installer won't want to do that. Then the decision is do I want him to install the antenna he brings?

    Unfortunately that's not going to fly too well. My wife is already POed that I'm getting the HDTivo. And she was really unhappy when I put the antenna up because it's so HUGE. I guess if I could talk him into using my mast and thus taking down what I have now that would be OK.

    But is is possible that a smaller antenna would actually work better? I find it hard to believe that the one I have is TOO GOOD. And I'm pretty sure the installer will be no help in making a decision. So that's why I ask the experts here :up:

    Your antenna could be too good if you can see the tower from your house clearly. Not likely, though.

    Midas, do u have a rotor on your HD-7084P antenna?

    This is the wrong thread but:

    With such a large and presumably high gain antenna only 14 miles away from the towers, I would be more inclined to put in an attenuator rather than an amplifier!

    And as Tom asked, do you have a rotator? A high gain antenna may need precise aiming. You might consider using a smaller antenna.

    Thanks guys. I wish I had a rotator on it. That would make life much easier and at least take care of one of the variables. I'll see what the installer says when he gets here Monday, although like I said, I don't expect him to know much.

    just curious if u'd tried to tweak the direction for a better signal which u could do easily with a rotor. I think we'll all be curious to hear what happens on Mon.

    That gigantic (high gain) antenna should be pulling in a strong signal from 14 miles. I bet it's been moved by those strong Chicago winds or maybe there's a short in the line as Doug suggested. I almost bought the same model Winegard(HD7084P) to pull in ota from almost 70miles but decided to go with the largest model at RS cuz they had it in stock and on sale at the local RS store (VU-190XR) 160 in.

    I've waffled on getting a rotor for a long time. If could get on the roof and do it myself I probably would have done it a long time ago. But paying someone to do it really raises the price. I just figure that once I find the sweet spot I'll never have to move it again.

    Well, for that $60-$90 you can actually find the sweet spot without numerous trips up and down a ladder to move the antenna, go look at the signals, take notes on reception quality/strength, move the antenna again... ;)

    Plus with the rotator, you'll be able to play around when there's a good troposheric forecast and see what else you can pick up.

    Oh I agree, if it were only $60-90, I'd do it. But to have someone come out and do it for me would probably cost at least another $100. Now we're talking about some serious coin.

    IF you can get on the roof to move the antenna can't you put a rotor on too???

    I can't get up on the roof at all, that's the problem. Oh well, the installer just left and it was an interesting experience to say the least. But I throw the details in the $99 deal thread.

    Since HD programming info is in the FAQ, then I guess it is OK to ask this here...

    Has anyone contacted DirecTV about Bravo HD availability?

    I just received an email back from them. They can't comment since it isn't announced, but my request will be forwarded to the programming people...

    Oh well, maybe sometime. Significant Others is a great show....I'd like to watch all TV in HDTV.

    Do I need a satellite C kit? I currently have a 3-year-old elliptical dish and receive HD on my SAT-HD100, which I assume is pointed at 101/119. Apparently the C Kit will add 110. What exactly will I be missing if I don't add the C Kit to get 110?

    midas-

    I also live in Chicago...North side along the lakefront.
    I had gotten on that directv customer retention deal for a HD receiver. had it installed.
    Well, I have a midrise building that is in direct line to the Hancock building (and in line with the Sears also). The off-air antenna they installed did me no good.
    Bought an amp'd antenna to see if I could do better. With Too Much dicking around, I was able to get 5, 7, 9, 11, 32, 50 (others too, but those are all I cared about) But, the position for some channels knocked out the others. Never could get 2 in at all. Meaning I would have to be constantly moving the antenna to get all the available channels I listed.
    That said, I find HD at this point to be quite a disappointment and as of today, got DirecTV to take the whole thing back. Much of the off air stuff is in 4:3 resolution, not 16:9. The DirecTV HD channels come in good and look very good, but honestly, not so amazing compared to the general great quality of standard res Directv. To me there simply isn't enough HD stuff that I want to even watch. Also, what the heck was I thinking, thinking that I could look at non-tivo'd TV. What? Watch shows live and on time? No way :)

    As to the Upcoming HD DirecTiVo....At this point, not even close to being worth $999,at least to me.
    The experience was educational just the same. My longing for HD is now on hold until there is much more HD content available.
