Eliminator I'm near you, opposite Woodbine race track and my receptions of Buffalo, Toronto is very good, except Omni2.
My antenna CM4228 is mounted on the chimney, about 30-35 feet above ground.

I'm at Hwy. 427 and Rexdale, just east of 427 and near those two monsterous Trimark highrise buildings.

The two Omni HDTV are not ON know, but when they are I can get omni1 and not omni2. I've tried moving my antenna little east, then omni2 is OK but PBS(43.1) signal drops. I rather have PBS than omni2. I don't understand why the reception from all the stations on Bank Of Montreal tower is OK an not omni2.

My antenna CM4228 is mounted on the chimney, about 30-35 feet above ground.but see 30-35 feet above the ground is about twice as high as mine... last time i saw omni 1 and 2 on was about a year ago and they were both coming in very strong at around 95%

Hey Guys,
picked up an early xmas gift for myself a couple of weeks ago, in the form of a Sony KDL46XBR4 LCD HDTV. I've been nothing but happy with it and my OTA reception results. All my previous woes with reception using the Hauppaugge HVR-1600 are not at all apparent with the tuner in the Sony set. I'm getting decent reception of channels I had no chance of getting with the old PC card.
To re-cap, I have a CM 4228 mounted on the chimney, but my view of the CN Tower is blocked by one close-by apartment building, and the "view" between me and most of the Buffalo towers is blocked by another group of 3 apartment buildings. The antenna is pointed about 10 degrees east of south. I have a CM 7778 pre-amp mounted just below the antenna and then a cable run of about 60 foot to a 4-way splitter. I also have a 10dB attenuator in-line between the LCD TV and the antenna (total drop is about 17dB summing the losses from the splitter and attenuator.) Anyway, here are my results -
Channel Strength SNR
2-1 54/100 24.5
4-1 76/100 28.5
5-1 93/100 31.2
7-1 93/100 31.5
9-1 60/100 25.5
23-1 93/100 31.3
25.1 93/100 31.0
26.1 27/100 19.8
29.1 87/100 29.6
43.1 93/100 32.0
49.1 21/100 18.1
57.1 65/100 26.4
66.3 71/100 27.0Almost every channel is rock solid now. The only channel I have any real issues receivng is WNYO, but I expected that from reading the rest of the reception results. Needless to say, I'm extremely happy with what I am currently getting.

Thanks to all who replied to my earlier posts with advice and encouragement and thanks again to Yaamon for the CM4228.

my TV can't catch any signal from NBC or PBS (my two most wanted channels, aside from cityTV).

I'm about 10KM northwest of the CN tower. and pointing my antenna slightly to the right on the CN tower. does that sound right?
Actually, it should be well to the right of the CN tower. Grand Island, NY (where the most of the Buffalo transmitters are) is approx SSE of us. I suggest aiming straight down Rockcliffe Blvd as a first cut. It should be a definite improvement.

I have a strange situation, and can't find a solution after searching this excellent forum. My setup;
ministate 5ms9000 on 12 foot mast mounted to chimney, viewsonic 9000hd satellite receiver with built in atsc tuner.
I am very pleased with reception results(plan to post in appropriate forum later) and surprised by the incredible improvement over analog broadcasting.
Now the problem; I get an excellent signal on suntv channel 66 (shown as 65 on this receiver, which has channels listed 1 through 68 for some strange reason!), yet the receiver doesn't recognise any station. I receive all other T.O. stations flawlessly. Any of you good folks have any ideas? Is suntv temporarily off line?(no indication of such at their web site)
Thanks in advance for any advice offered, and please forgive my newbieness, lol.

SunTV is coming in problem free for me. See if you can manually enter 66-3, as that is where the PSIP remaps to.

Thanks Cyclism. By 66-3, do you mean the 3rd subchannel of 66? I thought Canadian broadcasters didn't use sub channels. Please forgive me if this is a silly question, I have very little knowledge in this field. The only things I can edit on tp screen are frequency(currently 785), symbol rate(10760), polarity(auto), fec(2/3), and modulation(dvb). There is also option to add user tp or channel. I don't know if any of this means anything to you, but it's mostly jibberish to me! (I should be ashamed as I have had some electrical engineering schooling way back in the day, lol). Being that this receiver is geared towards satellite reception, I suspect it is set up differently than most atsc tuners.

Yes, I mean you have to tune to the 3rd subchannel of 66 to get 66-3 or 66.3. SunTV and other Canadian broadcasters do not use subchannels, but SunTVs main channel maps to 66-3 without any other subchannels. As I don't have the same equipment as you do, I cannot tell you how to do it.

Well now I at least know why I can't get this station, and I don't think there is a way around it with this receiver. Thanks for the help, Cyclism(and sorry about that cross-post, I am as new to online forums as I am to OTA, please forgive me) Cheers!

There is also option to add user tp or channel.
"Add a channel" looks like what you want. Try that menu and answer "66", and see what happens.

i have rf but can't lock onto SunDT. neither of my tuners can get subchannels without the main channel.

I believe my receiver has the same shortcoming. I have a strong signal on 66, but no channel recognised by receiver. At least I'm not the only one with this situation, as they say "misery loves company", lol. Thanks Tom.F.1!

"Add a channel" looks like what you want. Try that menu and answer "66", and see what happens.
Thanks for the suggestion, but adding a channel that's already there won't help, unless there were a way to make it recognise the third (and only) subchannel, which doesn't seem possible with the parameters I can add/change. Appreciate the input, though! cheers!

Update to Post #354 in the Toronto INDOOR antenna thread:

So....

I setup the CM 4221 in my attic last weekend. It is a big improvement over my RCA loop antenna which I have returned to the store.

I simply screwed in an insulated metal hook into the top rafter support beam in the apex of my roof. I'm hanging the top of the 4221 from the hook. And I'm using a few strings to tie down the bottom of the 4221 to 2x4's in the attic.

My attic is pretty unfriendly as it has lots of nails, no floor, etc. So this is the best I could do in terms of mounting. But in fact, I think the mounting is pretty good. The antenna is at the very highest point within the house, and it is somewhat adjustable. If I pull on the strings I can rotate the antenna.

I have a CM 7778 preamp installed as well.
From there I have a splitter and I am feeding 2 plasmas.

Here is my setup and results.

Location: Yonge & Lawrence. North/West quadrant.
CM 4221. attic install
CM 7778 preamp
2-way splitter

I've concluded that the ATSC tuner on the 5070 is better than the tuner on the 4360. The 4360 is a least 2 years older than the 5070. The 5070 reports much higher signal strengths throughout. And if I am ever to see Fox or CBS it will usually be visible on the 5070 and not the 4360. I got the 5070 in 2007, and the 4360 in 2005. I think I may need an external ATSC tuner for the 4360 if I want to pull in Fox and CBS reliably.

I seem to be able to get NBC pretty reliably. For some reason I cannot get CBS or FOX at all times, even on the 5070. I was able to get CBS using a loop antenna before though. Perhaps my antenna is not pointed quite right. I pretty much just pointed generally south and have not adjusted it much. Since the 5070 reports 30% signal on NBC, I probably do not have a lot of adjustment room to play with....

Are these good results? I'm not sure if I can do better....

I'm currently using a 4221 on my roof at Alliance & Rockcliffe

I've got:

5
7
9
23
25
29
43
57
66

Channels come in clear except for 7 and 43 that cut out in poor weather conditions.

I REALLY want 2 and 4 (CBS, NBC).... Currently, I have absolutely no reception for those channels.

If I upgraded to a 4228 would the upgraded antenna potentially give me a steady signal? Or is the upgrade from 4221 to 4228 not worth it if I can't even get a bit of reception in the first place?

If I upgraded to a 4228 would the upgraded antenna potentially give me a steady signal? Or is the upgrade from 4221 to 4228 not worth it if I can't even get a bit of reception in the first place?I'd try a CM 7778 pre-amp first. That really helped me a lot to get steady signal even on 34.1/49.1 in even the worst weather conditions.

n00b question, but the pre-amp won't blow up my TV if it's connected close to my TV set, rather than close to the antenna right?

The preamp has to be mounted right up as close as possible to the antenna:

Hi all,

I can receive signal from the weakest transmitters and from the strongest transmitters, but I cannot receive this particular channel (CBLT5 20-1 on 5-1; 30kW transmitter).

I am in Toronto (Etobicoke, west of CN Tower). My CM4221 clone (AT-MB04 4-bay antenna on tripod) is pointed at Buffalo (SouthWest), on the balcony on 8th floor - there is no clear view of CN tower. 25' cable between antenna and receiver, no extra amplifiers on the line.

My receiver is Samsung DTB-H260F. I am able to receive every single channel from this list:

2-1
2-2
4-1
7-1
7-2
7-3
9-1
15-3
23-1
25-1 (CBC in French)
26-1
29-1
29-2
43-1
43-2
43-3
49-1
49-2
57-1
66-3

(Losing 57-1 CityTV and 66-3 SunTV sometimes, depending on weather; all other channels are great). See photo here:
