I also have pixelization problems with CHRO. I'm between Albion on E, Hunt Club on N, Airport Pkwy on W. I get 13 digital channels, all perfect except CHRO. The CHRO reception is solid ..... except for pix. I put a call in to CTV Ottawa. I'm happy others have the same problem cuz it means the problem source is with CHRO.

I finally managed to get Global this morning on my set up by sticking the rabbit ears on the roof. So as I suspected, antenna location (mostly height) was the culprit. However, I cannot combine this input with my CM 4228HD into the CM 7000 ATSC to Analogue box.

I have a feeling that there's a simple solution but my brain isn't working. Is the 4228 signal just over-powering the rabbit ears even though one is getting VHF-Hi/UHF and the other VHF-Lo? Unfortunately, an A/B switch isn't a practical solution.

what you need is a VHF/UHF combiner...

I've tracked this thread for a while, and just want to report my reception results.

From Kanata North, I get all 13 local digital channels clear and solid with a RCA amplified indoor antenna installed in the most south-east room on the second floor and pointing towards HC.

I have to do one trick with the antenna. Instead of placing the VHF rabbit ears vertically, I place them horizontally to form an angle pointing towards HC along with the UHF loop. This turns out to be a very good UHF booster.

The amplifed signal is then sent to the basement via a RC6 cable and distributed throughout the house.

There is nothing to brag about (as I don't get any US channels), but may be of interest to someone who's on a budget or who don't want to install an outdoor antenna on the roof or in the attic.

tvlurker are you sure CTV - CJOH has completely correct PSIP ? see above post.
I stand corrected. I don't have TSReader, so I can't check if CJOH/CHRO followed all the rules.

I was just comparing them to other stations that:

- have the wrong System time, from 14 seconds slow (Global and the three Rogers stations) to one hour off (CTS) to horribly off (TQ, TVA)

- have no Program info at all (Global, although they're planning to add it, and most of the others)

- CHOT has misprogrammed the audio feed, so my converter box can't detect it (My EyeTV tuner can, but it lists the audio channel as "unidentified".

- several stations are sending out both "English" and "Espanol" audio channels.

- having seen much digital closed captioning on the new stations

- CHCH is horribly low bit rate SD (<2MB/s)

So everything is relative, I guess.

And Rogers still hasn't got a signal for TeleQuebec.

Interesting results tonight.

On this morning's scan I lost CBOTF and tonight I lost CBOT.

These two channels are ones I have always been able to pick up in the past.

Hi All,
I've been following discussions on this forum for years, but this is the first time I'm chiming in. Given the conversion, I'm thinking about upgrading my system and perhaps some of you have thoughts on if it will be worth the effort.

Here is my TV fool report:
http://www.tvfool.com/?option=com_wrapper&Itemid=29&q=id%3d838729154b99f3

I am currently using a set of PHILIPS amplified rabbit ears. They sit near a South facing window. The TV is very close. I pull in all 13 of the current local digital stations without much trouble, sometimes a little tweaking of the antenna is needed. I am finding 13.1 is a bit more difficult to get consistently than it was prior to going digital, which is my main reason for considering an upgrade.

My intention is to install a CM4221HD (modified) in the attic with a set of rabbit ears for VHF up in the attic as well. I would also add in a CM7777.

I don't want to go outside, I'm concerned about properly grounding the system, the information I have read does not give me a clear sense of how this should be done.

Here is what the TV Fool report looks like at 25ft:
http://www.tvfool.com/?option=com_wrapper&Itemid=29&q=id%3d8387bd6cc6cfdf

I guess I have a couple of questions:

1) is it worth the trouble of installing a better system in the attic if I already get pretty good results with my basic setup next to the TV?

2) Will I have directional problems with the CM4221HD, given that it will likely be pointed Southeast... will I still be able to pick up the stations to the North?

3) What do you figure my chances are of pulling in 18.1 with such a setup? From what I have read, some have had success... I guess it depends on how much of a burden the attic materials are for the signal.

Thanks!

hi tmac and welcome.

1) is it worth the trouble of installing a better system in the attic if I already get pretty good results with my basic setup next to the TV?

You're currently next to a window and you'd go in the attic. That could boost your UHF channels but it may make it harder for your VHF channels: 6,9,13(yeah, Global, SRC and... CTV)
You'd want bring rabbit eras in your attic and see if 13 gets better there or actually gets worse.

Having a good setup usually makes a difference when there is bad weather. If your setup brings a much stronger signal and your SNR is higher, it will be able to withstand worse weather without losing reception or simply seeing pixelation. You can see what signal levels you are getting now. See if you're experiencing signal loss once in a while - during the day, for example, when signals would be at their lowest levels, or during bad weather.

2) Will I have directional problems with the CM4221HD, given that it will likely be pointed Southeast... will I still be able to pick up the stations to the North?

The 4221 (where are the 4221hd charts?) does have back side lobes, and based on your angles, it looks good. Assuming the 4221 matches the 4221hd, you'd be OK.

3) What do you figure my chances are of pulling in 18.1 with such a setup? From what I have read, some have had success... I guess it depends on how much of a burden the attic materials are for the signal.

Exactly. I don't feel well giving you an estimate of loss. You'll get it sometimes for sure in an attic with the 4221hd and preamp, but whether it will be 100% reliable i prefer not to answer that !

Thanks for the reply Flavoie.
I am quite certain that I want to try and set something up in the attic. The reasons being that I won't have to deal with the rabbit ears in the main living area all the time or have to adjust them. From what I have read on the forum, outdoor installations are pushed/preferred by all. From Flavoie's post, I take it that if I did mount something outdoors, I would have a good chance of picking up 18.1 consistently. I've been looking all over the forum trying to find information on grounding which I would need if I decided to go outdoors and I haven't found much... and the only real benefit to going outdoors over the attic (at least I think it is the only benefit) is better consistency for 18.1. Are any of the other US stations a possibility from my location with an outdoor setup? 7.1 would require a strong VHF antenna on top of the 4221, adding to the size and complexity, and from what I have read in the posts on this forum for our area, nothing else is really achievable. So other than a more consistent signal with 18.1, is there any other benefit to going to an outdoor setup in my case?

tmac, you'd need a grounding wire, a grounding rod and a coax grounding rod for grounding. There's a long thread about that, but here's the more important part, courtesy of roger1818, a long time contributor from Ottawa/Stittsville.

has the problem corrected itsself for you
it started working for me but then completely dropped off again

funny thing is if i take an old 4 bay bow tie
connect straight to tv
and point about 15-20 degrees east of HC
it works solid but of corse nothing else comes in

who did you talk to at CTV
i have called 3x but keep getting generic VM with no call back

Before the switchover I received CHRO great.... Since the switchover I haven't been able to get CHRO. Did the transmitter location change or something... or are they having trouble stabilizing their Digital signal transmission? Anyone have any thoughts? I stopped receiving 4.1 and 9.1 over the last few hours as well. Everything else (digital) comes in as before....Is this a break in period where the stations iron out problems or is change required on my end. Thanks

Landowner, did you rescan to get the new channels ?

Landowner
2011-09-02, 08:29 PM
Thanks. I rescanned and the channels are back. Much appreciated!
The only one I'm missing is CTV2 (the old A Channel) it should be coming in on 43.1. It worked before the conversion. Any ideas?

Hi,

I'm just getting started but i am very interested in putting up an antenna on the roof of our new home. Would any knowledgeable veterans out there provide some advice on which antenna's would be best and any other details based on the TV fool results linked below? Thank you.

Hi everyone,

I have an attic CM4221HD running 65 feet of coaxial to my basement and here is my TVFOOL:

http://www.tvfool.com/?option=com_wrapper&Itemid=29&q=id%3d8387ad85ea39df

My wants: The most important channels for me would be CBC, CJOH, City, and Global. I know that Global will be next to impossible to get. I would like to see the others at a very strong signal because I assume that in winter the signal will degrade due to the snow.

My question:
Which direction should I point the direction? Currently I have it pointed SW. I am currently getting City about 65%, CTV 90%, CBC 85%. It looks though in TVFool that my antenna should be pointed to the east (north east?)? I have looked at others with antennas and it seems that most everyone is pointing them South West.

Also, should I consider a CM7778? The signal will be split to 2 TVs.

Thanks for any feedback. Appreciate it!

If you are in stittsville you probably want to aim it ESE to Herberts Corners. Maybe a little more SE to try to get some US stuff.
A preamp will almost always help.
