post #811 of 10300
I'm sorry....my statement didn't come across quite as I meant it to. I COMPLETELY agree with the tremendous improvement DTV brings over analog. It is just as big a difference from B&W to color (if not more because of the SOUND improvements as well) . What I meant was that a fuzzy ghosty analog reception could at least be watched, whereas today, when my audio and picture was dropping completely out every 7 seconds, I had to switch back to the SD satellite feed of the WHNS broadcast just to watch the game.

Jerry...I know we have discussed this before, but you would recommend me replacing my long distance directional VHF/UHF/FM antenna and Winegard preamp with a UHF 8 bay antenna and a CM 7777? Would simply adding a tripod and a rotor and the cm 7777 do the trick instead? I am just a little leary of spending another few hundred dollars on an antenna to improve the signal on one station when it may simply be that a better preamp or even raising the antenna slightly more would help. Also, if WHNS is still getting all their stuff configured and maybe even boosting power, then I would be getting everything there is to get in my location.

Thanks for all the replies!

Perhaps the only stations in this area at full power at this time are WSPA and WUNF-DT. As rchalk's posting says, the new generation receivers are designed to solve many DT reception problems. To speed up the process for you I suggest a $50 investment in an 8-bay antenna, or a less than $30 in a 4 bay (various places on the Internet.) CM's two antennas have proved over and over to be excellent. The 8 bay may improve the signal from directly in front of it, but it is very directional and it's side lobes drop off quickly. You may have to re-orient its direction more often than with a 4 bay. The less combining of signals (as in all-band antennas or multiple antennas), the better. Each coupler cuts the signals in half, at best. Thus, I find the rotor a good investment to cover multiple location of transmitters. But, I would try the CM antenna first to see if one orientation will provide stable signals from all stations. It does for me. In-the-attic mounts success depend to an extent on the composition of the roofing material, but asphalt tiles generally pass the signals with little attenuation, except in wet weather. With the gain of the CM bowtie designs or the Yagi type antennas, you usually will have enough signal from the antenna to overcome the weather attenuation. The one problem I have with my in-the-attic antenna is if the antenna is turned directly toward the metal chimney (12 feet away) for WSPA; it will attenuate the signal and I have to point the antenna about 10 degrees away from the station for best results. Who know what full power for all stations will bring...more multipath?...more co-channel? Perhaps the new chip is the best answer to our problems.

All: Strange that WSPA carried a network feed approximately 90 seconds ahead of the CBS HD satellite feed last night between 8-9 p.m., and in SD. Did WSPA switch to HD feeds later in the evening?

After day 1 with the 42we655 i'm very happy. The PQ from charter cable on this set is very nice, as good or better then our 9 yr sony we have been using and this is with just using coax cable until i can get a HD box from Charter. My main issue now is with the antenna for OTA, i checked out my attic last night and there isnt alot of room for much up there. My wife has stated no antenna is going on the roof of our house and i think our covent will not allow it either, hell i cant even put a window a/c up. From the antenna website it looks like
CBS 0 deg 27.8 miles
PBS 327 deg 15.1 miles
TBn 327 deg 15.1 miles
UPN 337 deg 35.7 miles
WB 195 deg 8.5 miles
Fox 325 deg 37.7 miles
NBC 325 deg 31.3 miles
To me it looks like most north/Northwest i jsut have to figure out where the heck i'm going to put a antenna. Last on NBC crossing jordan there were black bars on top/bottem, there was the only show all day like that and no other shows on NBC were like that.

This has been discussed many times on AVS Forum. A Homeowners association CAN NOT keep you from putting up an antenna, this is per FCC Federal Regulations.

You would almost have to have a flat roof to keep you from installing a 4 Bay CM bowtie antenna. The turning radius is only about 8.5 inches. Look at the specs on CM website. Even outside installations can be hidden nicely on the exterior of most houses. I have no problem shooting through trees...which means some vegitation around it would not be a disaster. If your wife has any favorite HD programs...wait until she sees the quality of HD and that should change her mind...as has been the case for many.

I had recorded "Cold Case", and during playback, there was a gap at about 8:30, and the balance was in SD. I had a quick look at about 10:30, and the movie was in SD.

Maybe they lost the HD feed. The DVR stops recording if there is no signal, and resumes when the signal returns, so I didn't get to see what might have been on during the gap. I only know that there was a discontinuity in the program...

lol This might be true but the FCC does not control the loving in my house, my wife does so she has way more power then the FCC or Home Owner association.

All the above are in the analog Grade A for you except perhaps Fox...and the fact that most are not at full power must be taken into consideration. However, the most important factors are your environmental conditions between you and the transmitters. I have yet to see HD contour maps for this area (nor for Miami and Atlanta as a matter of fact; probably because of the universal low power at this time.) The predicted contours are excellent compared to analog.

For this area almost due North is usually the best. If you go with a CM 4228 you may not need a pre-amp, but I don't think it would hurt either. The issues that Jerry speaks of regarding the CM 7777 pre-amp seem to be unique to the Asheville area as everyone I've talked to in the Greenville area has only had a positive experience using a pre-amp. Before I settled on my final setup I went back and forth as to whether or not to get a bigger antenna, a rotor, a pre-amp, or different combinations of the three. For me the pre-amp made the difference, but I've got a different antenna from most so I can't say my results would apply to everyone.
post #821 of 10300
I'm using a deep fringe yagi, pre-amp, and a CM rotor on a 30 ft telescoping mast. I get excellent SS on all stations. And I am in Enoree at the bottom tip of Spartanburg county.
post #822 of 10300
I agree with all of the comments from previous postings. As you can tell, if you point your antenna due north, you might not be able to get WB (WBSC Ch. 40). That's the situation for me. I have a rotor on mine, so I just spin my antenna around. A rotor is also useful when weather condition get harsh, so you can "center in" on the specific station you want to watch. If you have a highly directional antenna, a rotor is a no brainer, but they are also useful with "mult-directional" antennas, such as the 4228. Preamps are a toss up. If you need one, use it, if not, then don't. There's no one solution that works in every situation. It's mostly a trial and error process...see what works for you.

Any word on when WLOS will boost its power? Now that FOX is up, ABC is the only one I'm missing.
post #824 of 10300
Jon, you do not need much space in the attic for the CM antenna that will help you. Do NOT let the wife affect your antenna choice, you will regret it in the long run. I live near Simpsonville, my 4228 is in the attic, and I get all the channels. I have a rotor but rarely use it. Call me or e-mail me and I will tell you how I did it. An antenna in the attic will work. Did you REALLY want to get on the roof and mount that thing, run the wire and everything?

on a totally unrelated topic: has anyone tried to watch "Desperate housewives" in HD on WLOS-DT? The picture I am getting is totally unwatchable - very jittery and jumpy. It will be fine for a few secondss - then the audio will slip and the picture jumps. Anyone else seeing this? It has happened to this show the past two weeks. I do not have the same problem watching MNF. what is the deal?

Calvin do you have a Hughes E86? I have watched all the episodes of this show with no problems. However, WLOS is the only channel that has constant audio drops and pixelization on my Hughes E86. The channel comes in rock solid with my RCA DTC100. I hooked up the old RCA and only use it when I watch WLOS. Hopefully this E86 problem will go away when they boost their power.

This is a newbie question on CM 4221 antenna. Which way should the antenna face in order to get most of the signals? I need to aim between +340 degrees and +10 degrees to get the best picture and I want to try and aim the center of the antenna at +350 degrees. Should the center of the flat surface be pointing in that direction or should side that has the prongs and where the coax cable gets connected be pointing. I have tried to point by trial and error and get mixed results.

Thanks

Re CM 4221 orientation

Trial and Error is the only solution. Two or three degrees can make the difference in receiving most all stations, and the loss of even the nearest, strongest signal due to phase cancellation. I point my antenna at the weakest (WLOS) signal, and it receives WSPA which is 90 degrees to the left. However I have modified the antenna to broaden the pattern...mentioned several months ago on this forum. If you want to try the same thing, let me know.


Your location may be totally different.
post #829 of 10300
I have experienced zero problems with WLOS since I was able to receive it once I got a rotor on it. I have a Hughes HTL-HD. I'm getting an 80+ signal strength, and the signal is 100% stable...no pixelization or audio drops. Sounds like a lack of signal strength for those of you having problems.
post #830 of 10300
Getting 94 on WLOS in Enoree with my yagi, I also get 82 on WB40 from the backside of my antenna when the front is aimed towards WLOS, as the WB40 tower is in Fork shoals vicinity.

It sounds like you have the setup that all digital OTA enthusiast salivates to have. What are the characteristics of your particular location? I mean, do you have lots of tree or other objects? Do you live on a hill or in a valley? I know your antenna is good, but just wondering about the details of your location. I'd like to pull in some more content, but I know surrounds has a lot to do with it as well, not just birds and poles.

I just my charter box and i found myself watch the Navy/Rice football game replay on hdnet. OMG there is no going back now. Even my wife was very impressed. She couldnt believe how good you could see the grass on the field. What are you guys talking about signal strength? is that on the STD you buy? I have almost turned my wife on the antenna after tonight.

Oh yeah where do i get a Avia DVD to calibrate my set. I know i can buy on amazon but i dont want to wait till next week to get it. DVD play seem alittle red to me.
post #833 of 10300
Since installing my pre-amp I get low 90's for WLOS, WSPA, WYFF, WHNS, and WASV. I get around 84 for WBSC which is the direct opposite of where my directional antenna is pointed. It's up on the 2nd story of my house, and I've got very good line of sight in all directions.
post #834 of 10300

The signal strength we speak of is for OTA reception of the local stations in the area. Right now, this is the best way to receive HD programming, as it is the best picture quality available, opens up the best world of programming, and is FREE! If you don't have a good antenna yet, get one, and join all of us (we'll help you with the kinks). For calibrating your monitor and sound, Avia discs are the best choice. BUT, some DVDs you buy might have a THX Optimizer section on them that work for a basic set. I've got Miracle and it has it. I think I read that the Lion King II does as well. Check some of your recent DVDs to see if it has it on it. Welcome to the world of HD, and strap in for the ride because it gets better all the time.

Thanks Dashaund i'm pretty sure we have LK2 dvd since i have a 4 yr old and 1 yr old LOL, i will use that till i can get one from the net. I'm going get a good antenna but i'm in TALKS with my wife because she doesnt want a ugly antenna on the roof and i'm trying to figure how i can get the job done in my attic. But i think things are moving in the right directions with her because of the HD she saw today, she watches alot of primetime tv.

Tonight i found channel 784 which is NBC HD. Man Law and Order looked sweet but i have a question. While watching ESPNHD and NBCHD i would switch back and forth to check the difference. During commericals the black line would show up meaning not in HD correct? But when i switch to regular channels the PQ was noticably worse and i mean a good bit worse. I was under the impression that the commericals are in NON-HD shouldnt they be the same PQ on both the HD channel and regular? Sorry for all the questions guys but honestly HD is so damn addictive and this forum is a wealth of knowladge that i crave. Thanks again for all the help i appreciate it.

In most cases, the SD signal you see during commercials is taken directly from the station's master control switcher, and is probably in Component Video. This gives you a picture virtually identical to the station's monitor, with the full available bandwidth for each of the three components. This signal is up-converted to the station's choie for HD of either 720p or 1080i.

The SD signal is probably delivered to the cable company over the air, as a composite NTSC color signal. This means severely reduced bandwidth, as well as the many artifacts present from the color-encoding system. These look acceptable on a regular TV set, but, since the typical HD display has to up-convert, the limitations of the up-converter may further degrade the image.

FYI..the Avia disc is available at Barnes and Noble $49.99 MSRP. Also check Best Buy, some have it, some don't.
post #838 of 10300
I am on fairly level ground with some heavy trees in the path of my local stations, I have a fairly clear path for Charlotte and Columbia stations. I get a higher SS on WBTV and WCNC from Charlotte than I do for WYFF and WSPA. I also get great reception for WOLO(ABC) in Columbia.
post #839 of 10300
(Potentially) silly question:

How much of a difference do leaves make? Will I notice any increase in signal strength after the all the leaves fall? I need all the help I can get with WLOS.
post #840 of 10300
Apps, I have the Samsung 360. Sounds like I need a pre-amp. Dumb question: where do I hook up the pre-amp: coax from antenna into preamp and then out to STB? I assume this is the setup. Is there a local source for the CM 7777? I need to check with Wholesale Electronics. Quick question for our Charter guys: do the HD STB's that you are getting (including the MOXI) have an input for an OTA antenna? I remember looking at one of the earlier Motorola boxes and being surprised that you could not add an antenna. What a POS if that is still true.
