In my area (Charleston), certain channels such as NBC HD and FOX HD transmit from the same tower. However FOX HD comes in perfectly whereas NBC HD does not pick up at all. The same goes for the CBS HD and the ABC HD channels which both transmit from a different tower, but the situation is the same. I get CBS HD in fine but ABC HD does not get picked up at all. The analog versions of all the channels are picked up fine.
According to the FCC website, WCBD (NBC) and WCIV (ABC) have been granted construction permits for high-power DTV transmitters, but their current temporary licenses are for low power.
According to antennaweb.org, both of these stations are easy to receive, which would be consistent with them being at high power. Given your problems, I would guess that the antennaweb info is inaccurate. But I don
Alright, thanks for the help.
My zip code is 29420.
Strange thing, though, is that I used to be able to get these channels in the past. It wasn't until about 2 months ago that they suddenly dropped from the TV. I tried reprogramming the TV to rescan for the channels, but that did not help.
I live in the zip code of 92505 and i get i guess what is considered fading from channels coming off the same tower. ABC comes in clear but fox and others such as cbs don't at all. When i view the signal strength meter it spikes from have basically no signal at all for FOX and CBS to having full strength. I have a UHF antenna on the roof with a 30db amp. the HDTV receiver is a SIR-T451. HELP!!! no one from bestbuy or radioshack or circuit city seem to know what i should do.
When I submit 92505 to antennaweb it tells me the only DTV station in range for you is PBS. Since you get ABC well, your location must be better than that of the
1. Could you give me a location closer to your house?
5005 sierra vista ave riverside, ca 92505
2. Are you referring to DTV or analog stations? DTV Stations.
i get telefutura (spanish channel in DTV) as well.
3. What is the antenna model number?
U-75R UHF (from radioshack)
4. What is the amplifier model number?
TV-FM Antenna-Mounted High-Gain Signal Amplifier (from Radioshack)
Gain: Typical 30db VHF/UHF
FM Trap: >20db at 100mhz
Gain Control: 0 to 10db cut
5. Have you tried moving the antenna?
Yes, have not seen a real benefit. This website says a 303 degree position and the antenna web says 290 degrees. i have used a magnetic compass to make sure these angles are correct.
6. Have you read the
Apparently you are behind a hill. From Mira Loma all the LA stations are easy to receive. The hill will make UHF reception very difficult for you. The results you are getting now say all is not hopeless. But if you are to succeed you must not make any mistakes.
I'm having a similar problem with CBS in NYC. All the major networks are broadcasting from Empire State, which I have a clear view of. I'm only getting half power on CBS compared to the others. Can you give me any help in finding any info on the FCC site regarding any construction they are working on. I've tried phone calls and email to them but they haven't responded. Thanks EZ
I am not sure what problem you are describing. If you are trying to receive CBS analog then a weak signal would give you some snow.
If you are referring to CBS digital then a weak signal might cause dropouts, which would be portions of the screen freezing, which would be obvious, severe errors. But if you are referring just to the signal strength readout being below that of other stations, then you have no problem and increasing the signal strength will cause no improvement of the picture.
If you can see the top of the ESB then reception depends on whether the antenna can see it too. That means no intervening trees or structures. (Power and phone lines are conceivably a problem.) If so then reception should be easy and a large antenna not generally necessary.
Sorry, I was refering to Digital. We have a UHF antenna on top of a 35 story building here in Brooklyn and a clear line of sight to the Empire State Building which is about 2.1 miles away. When I look at the UHF band on a spectrum anyalzer average power for all the other digital channels ranges from +16dBmv to +21 dBmv. CBS Digital on channel 56 is running about +8dBmv on a good day, and is the first to drop out at night.
When I saw the posting regarding low transmit power in Atlanta due to the temp broadcast tower for CBS, I thought it might be the same thing here in New York. I was just looking for any suggestions as to where that tower construction information might be located on the FCC site. It sounded like you had found on the FCC site some information regarding tower permits or mabe even construction schedule.
If not thanks anyway. If I keep bugging CBS here maybe they will give up some info.
EZ- Probably CBS has the weakest signal of the NYC digital stations. But at 2.1 miles line-of-sight you should be successful with a paper clip for an antenna. Overload could be a problem for you if you switch to a bigger antenna.
I bet WCBS is adjusting their equipment somehow. I see this most nights on the local NBC digital channel. They have the good sense to wait until after 11:30 pm to do this. But I watch Jay Leno most nights and I have to put up with dropouts that go on for about 15 minutes. Most stations still believe that nobody is watching their digital channel, so they don
Then take a look here since AntennaWeb is basically useless;
Channels 34, 47 & 49 share the same tower and have the same pattern. It appears that closer Fox & NBC affilates aren't listed for their digital stations. Only analog. Also notice they are on another tower. This list is dated 10/06.
Sheesh..............not much to watch. I'm glad I live INBuffalo NY;
