My home is about 25 miles from the transmitter and I get the 3 VHF stations, mine, 11, and 13 indoors on plain ole rabbit ears (about $10).

The amps sometimes cause problems and are sometimes attached to less than full size antennas. Position of the antenna can be critical. The transmitters are in Missouri City so being on that side of your home can help get a stronger signal. The top of a bookshelf can get a few extra feet of elevation. Also, if your home has radiant barrier siding or roofing the VHF signals may not penetrate as well. Some folks put antennas in the attic. There is also the possibility that noisy appliances (computer with the case off) may contribute to VHF problems.

You won't need a big antenna just something that's truly VHF and outdoors should be totally solid.

Also, there's tower work going on this week so you may find some of us on our aux antennas or at reduced power during the daylight hours.

Feel free to drop me a private message or call me at the station.

Thanx Marty, PBS was also one that was sketchy, also broadcasting on VHF (what's weird is I could get 8.2 and 8.3, but 8.1 would give me fits - they're on the same frequency, correct?) - why did you decide to broadcast on VHF vs. UHF? I know theoretically, VHF propagates better because of the lower frequencies.

Can you speak for KPRC and KHOU as far as the reduced power claim I found?

Unfortunately, my house faces west, so my back yard has the (2 story) house in the way!

I posted a simular comment a month or so back, but continue to have issues receiving KPRC on my indoor antenna (for main HDTV) and on another HDTV connected via ~60 feet of coax to an outdoor (on roof) combo antenna. I live close to the intersection of Voss and Westheimer. Symptoms include pixelating, audio drops, and screen blanking out. Re-orientating the indoor antenna helps somewhat, but ideal direction varies from day to day. Possibly I am receiving a true and also a reflected signal? I live in a neighborhood with tall, mature trees, but this has only been an issue over the last several months. I do have a smaller indoor antenna with amplifier and may try that this weekend.

Well, just went here (http://www.fcc.gov/mb/engineering/maps/) and saw HIGH reception levels!! Then I read the description and these reception levels are based on an outdoor antenna 30' high!

Mike,

All the channels are transmitted in the same 19 Mb/s bit stream from the transmitter. Kind of puzzling why you could decode 8.2 and 8.3 and not 8.1. I can't speak for the other guys. ABC, CBS, and PBS are on VHF frequencies (our old analog channels). KPRC labels with their legacy analog number 2 but acutally transmits on 35.

Lower powers are used in VHF but not as low as you might think. Part of that is because you only need to recover the bits to have a perfect picture. Also, DTV powers are measured differently. DTV power is expressed as an average number - our analog powers were peak visual numbers. There's about a 5:1 ratio of peak to average in the modulation scheme that is used for DTV. So a 1MW UHF digital has about the same peak power as before. (1MW in DTV vs 5MW in analog) The 316KW analogs would need about 60KW average to equal their old peak number. The FCC model however is a little strange between how UHF and VHF predictions were done. There's also a VHF maximum based on antenna height. There is greater over the horizon propagation of VHF signals plus higher man made noise levels in VHF. It's complicated. Stations across the country are still working on sorting out all these issues. I hope that helps paint the picture a little.

Marty

Marty-KUHT,

Where you stand on the 5.1 sound. Is it about ready to turn "on"? Particularly for the music shows?

Thanx

Anybody else notice the HORRIBLE picture quality on FOX 26 during the Dallas Minnesota game, or is it just me?
post #5797 of 6141
Eeets pretty bad in some shots. Particularly that elevated shot down the line.

Here's a good fairly up to date channel guide of the Houston OTA scene.

Oh kewl "The Three Stooges" now that is my kind of people. Finally something on TV worth watching.
post #5803 of 6141
Will this new subchannel on 39 be an addition to Universal Sports (thereby taking away more bandwidth from the main channel) or will it replace US?

True BUT he stated "BEGAN broadcasting"......it isnt 2011 YET (unless he is using a different calendar!! )
post #5807 of 6141
So what's happened to KHOU? I thought it was the dispute over pricing with Dish but now it appears channel 11 has disappeared from OTA.
post #5808 of 6141
It's off DirecTV too, they must have had a big uh-oh.

...and not surprisingly, nothing on their web site about it.

Country Music Fans:

www.tcncountry.com is on 46.1 broadcasting country music videos. Signal is pretty weak, I'm 22 miles away from the antenna farm. Just saw a music video from "Ole Swifty." lol......

Must be really weak; I'm in Westchase and don't see it.
post #5811 of 6141
I was able to pick it up in Humble tonight, but I wasn't able to get it earlier in the day. I hope it will switch to a higher power station soon.
post #5812 of 6141
Still no luck in Westchase -- my TV tries to lock on to a signal but eventually gives up.

Anyone watching the Texans on 39 tonight?? Seems they STRETCHED the video to blank out the bottom scroll from the NFL Network (poorly at 1st..you could still see the TOP part of the scroll...then they did a minor adjustment and it went totally away) That means they stretched an already 16x9 HD screen to something taller!! ...Oh well, I am watching the game direct via the NFL Network..

Man I hate Fox 26 here in SW Houston, Sugar Land/Stafford area. I get every channel with no drop out issues except Fox. Tonight it's unwatchable, it's dropping out and staying out for 20 - 30 seconds at at time. 2, 8, 11, 13, 20, and 39 are great. Heck even channel 55 is good.

26 is on the tower next to 13s and iirc 8 is on the 26 stick.....may need to play with the antenna setting to get a good compromise....from your location you should have a clean shot at the towers in the farm...
post #5816 of 6141
That's what so anoying is the rest of the channels come in great and I've played with the antenna in the attic several times. I hate to move it outside due to lighting wind etc...

Kage,

It almost like something else is going on with the antenna; perhaps some sort of odd multipath cancellation?

AFAIK almost all up here in the Spring area get all the major stations with attic mount antennas with no problems. It is rare that the antenna has to moved outside.

Perhaps try moving the antenna from one side of the attic to the other. Or perhaps an antenna with a narrow beam to focus on channel 26.

Have you tried just rabbit ears on the back of the TV, to see what it does with channel 26? Will it stay steady? (keep the ears short)

At the Cypress Creek level (very low) about 34 miles from station; 26 comes in with this 3.5 antenna (one ear) on the first floor.

Well the Texans lost again; but as far as the picture was concerned it was great here.

Before the start of the game they had a black ticker stripe at the top of the screen and later when the game started they moved it to the bottom. Aspect ratio was correct here. Somewhere in the first quarter I went to sleep LOL

My 1080 display is set to 1:1 pixel mapping, and with the black ticker at the top, it may have had a thin white line on it (very top-one row of pixels). When they moved the ticker to the bottom, that all went away. Also, (before I went to sleep), going to and from commercials they would change or adjust the 16:9 mask - once I saw a 1" black bar running down the left side of the screen for about 1 minute - then a change of source (commercial or whatever) and it went away.

PQ was excellent, almost identical to CBS, high speed pixel squares were close to zero, so they were pumping out good bandwidth. 5.1 sound was clear and undistorted. Sorry I did not sit up in the chair and try uncompressed sound for full theater effect, so do not know if it matched FOX or CBS. But even asleep on the couch I could tell it was vastly superior to local ABC for both picture and sound.

I do know that VICK did move very fast.

post correction: Um, after reading your post more closley; I think what you saw happened after I went to sleep. LOL

I wondering if it is some strange multipath issue my self. I have a youtube 4 bay that I did a year ago before the full DTV conversion and I hooked it up and Fox is perfect. No drop out or those type of issues.

I don't have any side to side room so my only option is to move it back to another rafter and see if that helps any. Might try this this weekend.
