I'm wondering if the pq issues have to do with the new D* agreement with KHOU. It's absolutely terrible.

Hopefully they're remember which button that was :-P

i sent an email about 45 minutes ago to khou. maybe they were reading the emails.

I hooked up my antenna and the OTA quality was much better than the picture coming through D*. I called up D* to report it and they said they hadnt had any reports on it yet, but they would escalate it to engineering. I noticed the blip during the 3rd qtr when the picture went out and whether it was at KHOU or D* they seemed to have gotten it resolved.

Really... (!)

TSReader shows them running 13.20 Mbps now and the PQ is gorgeous.
You can't carry live action sports at 11 Mbps.... you just can't.

All of the satellite companies receive KHOU over the air. I'm sure the problems everyone has been seeing with the freeze ups and quality are due to the satellite companies equipment.

The game was amazing on OTA.

If you sent it to the assignment desk, it was ignored, as there are no engineers there on the weekend... only on call.

Has there been any word on what KIAH plans to do with channel 39.3 once Universal Sports leaves the airwaves?
post #5980 of 6141
Hi, I live in Katy and considering dropping Comcast. Would like to try out OTA HD and antennaweb shows I can use a small indoor type. Plan to place it near tv in window that faces south/southeast. Only problem is that we do have a radiant barrier. Questions are do you think a small indoor antenna will work with the radiant barrier and if so, can you recommend one? Thanks
post #5981 of 6141
Hi Wayne,

I think that you may have trouble with the V's at that distance indoors. You might look at something like the C-5 Clearstream on a wall outside as high as possible or perhaps on the side of a chimney. I've had some pretty good reports on it and it does the U's OK as well.

Let us know what you decide to try and how it works.

The difficulty with radiant barrier is that it also serves as a RF energy reflector/blocker. No RF passes through it, much like the wire mesh that is used behind stucco. Add low-E glass (metallic film) and/or wire window screens and you've effectively created a http://en.wikipedia.org/wiki/Faraday_cage out of your living space.
post #5983 of 6141
I agree with Marty. I live near Cinco Ranch and don't have a radiant barrier but the VHFscan still be a challenge with an indoor antenna.

I can't comment on the Silver Streak, but I have 2 separate antennas for my OTA down here on Galveston Island: A Clearstream4 for UHF and a Clearstream5 for VHF. I mainly got the C5 because of just ONE channel: Houston PBS Channel 8.1 would not come through whatsoever (of course) on just the C4 UHF-only alone, and only sometimes on a UHF/VHF RCA ANT806 amplified antenna I tried earlier that SOMETIMES got Channel 8 but mostly, weak signals or nothing at all.

The C5 is mounted a few inches above the C4 a 7-foot portable mast (on a tripod) inside my apartment -- with an EU385CF signal combiner box in between them also on the mast. Although both are OUTdoor antennas, I am using them INdoors...specifially, in my bedroom next to a window but pointed at the windowless North wall of the room. Just beyond the wall is another section of the building so the signal has a lot of walls to get through (or around/over).

Both antennas are pointing in the very same direction. Signal strength 99.99% of the time is a rock-steady 100 on all the channels and IIRC, I'm about 40 miles from the antenna farm in Missouri City. Don't know if I need it or not, but I AM using the small signal amplifier ("power injector") that came with the RCA ANT806, just for good measure.

And my apartment is on the 5th (top) floor, so that helps a lot I'm sure, even though I am not on the "proper" side of the building (facing MO City) for clear and unobstructed signal reception: My balcony faces S/SW instead of N/NW for best and unobstructed signal reception.

Very pleased with this setup and impressed that even 40 miles away from the towers (and partly facing the Gulf instead of MO City) the signal strength is so high -- couldn't be any better.

thanks for all of the input. I will have to have a negotiation with my wife to be able to put the antenna outside. If I do, will let you know how it works out.
post #5986 of 6141
Good luck with that...

I needed mine indoors mainly because outdoors they wouldn't last long being so close to the water: Down here, anything made of metal corrodes almost overnight, so I wanted to protect my investment (expensive antennas) as otherwise they'd be scrap metal in no time. :-(

Wayne's TV, you may not have to give up an attic install despite having a radiant barrier. I have a RB in my attic (Al foil-coated OSB roof decking) but check out my post here. I live a few miles away from you in the Energy Corridor area. This is the perfect time of year (temperature-wise) to check out your attic and see if you have a gable end of the roof where you don't have a radiant barrier. Look at the pic in my post and you'll see what I mean. With the relatively small Winegard HD-1080, I'm able to pull a clean signal on all channels even through brick on the gable-end but no radiant barrier.

If your house has a tray-style tall roof with no gable ends, then you will be out-of-luck and must look at a roof install. However, if you have a gable that faces approximately towards the MoCity towers, you may very well be able to pull off an attic-install which can help with the wife and HOA. More importantly, that way you can avoid the concerns of grounding your external antenna so that lightning strikes hopefully don't fry your TV & A/V gear. Final most important point is the safety issue of crawling around on your roof unless you pay a contractor to install it for you. Therefore I would exhaust all possibility of an attic install before even looking at your roof.

You can get a fairly large Channel Master UHF/VHF antenna at Fry's Electronics and try it out in the attic. If it works then you can get the permanent one at Solid Signal and not have to worry about a return restocking fee.

Me-TV has moved from 57.5 to 57.4. Pegasus TV has ridden off into the OTA sunset, opting to try for cable carriage.

Hi everybody.-
First, a belated thanks for information on the AVS forum that helped me connect my TERK HDTVa indoor antenna to my DELL W4200HD a few months ago. The step-by-step instructions for setup, which were in a reply to a previous poster, were exactly what I needed.

The TERK is a good thing, because it helped me pull the trigger on Comcast Cable and the monthly bill they used to send (the nerve!). The cost of even a limited plan seemed too high, considering the bad-to-mediocre quality of cable programming. Aided by a rectangle of aluminum foil stretched between the extended dipoles, the TERK is helping me see that there is plenty of bad-to-mediocre TV available OTA for free.

When I first deployed the TERK, I was happy to receive any channels at all. It sits near a southeast window in my second-floor apartment in the Heights (near Studewood & 16th), pointing toward the major antenna farm in Mo. City. I get KHOU, KTRK, KTXH, KETH, RRIV, KPRC, KXLN and others. Here's the problem: I cannot receive KUHT, even as a weak signal. When I go through automatic channel setup on my TV, Channel 8 simply doesn't register.

The engineering department at KUHT suggested several things I had already tried, then urged me to ampliify the signal. That seemed like a good idea, till I realized that the HDTVa is already amplified. Is it possible to amplify the amplification? Is it advisable? If the answer to both is "yes," how would I do that?

Has anyone else in Houston struggled to receive Channel 8, even with an antenna that picked up other local stations? If so, were you able to find a workaround? Thanks for any guidance the forum can provide.

The Terk HDTVa is scorned by many. I'm an exception. Although my knowledge about OTA has increased over the past three years, I still find the HDTVa to be an acceptable antenna. In spite of being in Dallas, our markets have many similarities (high powers and tall transmitting towers). I've since graduated to much larger antennas in my attic (AntennaDirect 91XG for UHF and Winegard YA-1713 for VHF) but the Terk HDTVa is still around for occasional testing.

At 40 miles from our antenna farm, the Terk HDTVa has no problem whatsoever with the three VHFs from Cedar Hill: 8 (55 kW), 9 (13 kW) and 11 (23 kW).

What might be worth pursuing is to make sure the VHF dipoles measure 14 inches on each side of the base. And position the dipole elements flat (90 degrees relative to the base) instead of a 'V' arrangement. Finally, aim the HDTVa so that the pointed end of the UHF "Christmas Tree" is facing Missouri City.

All of your VHF facilities have nice powers and good elevations and I would think KUHT's 64.6 kW signal should have plenty of saturation to reach you.

My final suggestion is to leave the power injector plugged in but switch it to OFF for channel 8. There may be too much amplification for that channel. If I weren't some 200+ miles away, I'd head over with my Sencore signal analyzer to take a look since that instrument takes all of the guesswork out of configuring an antenna.

I've got a 4-bay bowtie in my attic in the Montrose area, and we get KUHT-DT just fine. I have also had problems where I've been over-amplifying the signal in my home, so I second the caution on using too much amp. Amplifying an already amplified signal is probably chasing the bad with the worse. That being said, I was never able to get KUHT-DT indoors, which is why I went with the attic-mounted bowtie. If you have access to your attic, some zip ties, a length of RG-6 and a smaller outdoor antenna will do more for you OTA than anything designed for indoor use.

That's presuming the attic doesn't have a radiant barrier installed. If so, you're screwed...

Marty,
the one Gary Sgrignoli of www.mswdtv.com, who is putting on the DTV seminar at your place this year, recommends is the Vii from Digitenna: http://digitenna.com/products

He showed it at the seminar at KERA in November....Not cheap but it WORKS!! Add a CM7778 (which has lower gain on VHF than the 7777) amp on it and you have one hot indoor antenna...(Note to all: DO NOT place any TV antenna on TOP of your DTV....worse RF noise generator second to the PC in your house.....move the antenna at least 5feet minimum away...you'll see a difference!)

In my professional opinion, Terks are horrible...and the test results back it up....the amps are not that great gain wise and have poor noise figures!! The antennas dont perform as well as others with lower costs....check out Digitenna.com for a REAL TV antenna and use a CM7777 or 7778 on it...

you are correct on TOO MUCH gain can cause issues.....a lot of people throw amp in line with amp...EEEEWWW Not a good idea...use one amp and PAD afterwards if you have to (that way you keep the C/N ratio high and the noise low)...

Hello everyone,

I'm looking to get some advice on my next OTA step.

Here's my TV Fool picture, if interested

http://www.tvfool.com/?option=com_wr...7fb9acbb680018

I currently have an RCA751, based on my requirement to get KUHT, KHOU, etc.

http://www.solidsignal.com/pview.asp...ce=google_base

I currently have the 751 connected directly to my TV with a 50' cable running out of the window onto the roof (~15ft). I have the antenna pointed directly at the antenna farm and I can get everything perfectly, including a couple from Bryan/College Station, which is the other direction!

My question is, I need to now permanently setup the antenna outside, and I want to distribute the signal to 3-4 TV's in the house. I have a junction box in a closet and the house is pre-wired with coax and I already have a coax cable run outside to the 'dmark' area outside.

I don't know how long the cable is from outside to the junction box and then to each TV, but I would imagine it's greater than 75 ft and probably 35-40 ft to each TV.

How and should I place a splitter/amplifier at the antenna, or should I place a splitter amplifier in the closet?

Thanks for the help.

KVVV-LD has fired up their digital signal on channel 15. Currently their programming consists of Harry Pappas' commencement address to Cal State-Stanislaus; a PSA for the Foundation for a Better Life; and a station ID.

One thing I've noticed is that most of the Houston LPTVs are higher on the Missouri City towers than those in D/FW are on the Cedar Hill sticks. Even at 15 kW, how would you appraise their coverage?

And...what purpose does Daystar's KDHU serve since they already have a full facility in KLTJ?

Thanks for the info and nice blog, found a few other stations I didn't know existed, still nothing I want to watch on them, but they are still there.

Theoretically the low powers do a pretty good job of serving the southwest area. My friend who lives off 290 & Tidwell gets some of them with a set-top antenna.

As for KDHU... I suppose they're saving it for a rainy day. If donations dry up, they can sell and get a million or so.
post #6000 of 6141
I live in Pearland and want to put an antenna in my attic. From my TVFool report I can see that I need both VHF/UHF. My initial thought was to go with the ClearStream2 Complete, but is that more than what is necessary from what my report indicates? Is there another one that you would recommend?? My kiddo likes a lot of the programming on KLHT (channel 8) and I've heard some folks in Houston having issues with KHOU being weak so I want to ensure that the antenna can pick up weaker VHF signals. Thanks for the help!
