hdtv-illiterate to receive stable reception of the Toronto signals you need to face south-west.

Iam sorry but facing east your chances of you getting reception is almost none. If there is a building close and north east to you much taller and larger then reflected signals might work.

imique indoor antenna does not work that good unless the stations you are trying to receive is close by withink 30km.

If your antenna is close to the south windows there is a very good chance that you will be able to receive most of the stations being broadcasted off the cn tower.

How 2 combine two uhf antennas:

Can someone please help me with using two uhf antennas simultaneously? I use a CM 4228 on the roof for CBC and a RS bowtie antenna inside for the Buffalo locals. How can I use these two antennas together? I am getting some decent reception of Fox and PBS from the back of the rooftop antenna however I get better results from the indoor bowtie for the locals.

I've never done it, but from what I understand in order to increase gain with two antennas, you have to use identical antennas, with equal lengths of coax into the combiner, and the antennas have to mounted a certain distance apart (not sure what distance) and be pointing in the same direction.

I do know you cannot combine two antennas and have them pointing in two different directions.

You best bet would be a antenna rotor.

i've had sucess combining two yagi's pointing in different directions. I just use a regular 2-way splitter at the antennas, with two short coaxial cords going from the splitter to the two antennas.

i have one aiming at Buffalo, and one at Toronto, and it seems to work fairly good. The problem i'm having is CH out of Hamilton, which is all ghosting and weird colours...

i haven't figured out how to combine my CM4228 with my yagi's into my ATSC tuner.

my yagis can pick up the Buffalo stations but not the Toronto ones, so I want to aim my 4228 at T.O. and then combine these two into my tuner. Problem is, the (preamped) CM4228 powers out the yagis, so only the strong Buffalo stations get come through. It also reduces my Toronto recpetion by going through a splitter like this.

interesting.

well, as I said, I've never done it, I'm just going from what I've read when I was researching antennas a while back. your mileage may vary...:-)

No, combining with a splitter backwards is definitely NOT a good idea. It will introduce ghosts and the like, throwing off good signal and making it not so good. Either get a rotor or an A/B switch.
LET'S GO BUFFALO!!!

^ the combined yagis are for my analog system, so i don't care ha ha

Combining multiple full-range antennas pointed in different directions is generally NOT a good idea for reception since you're merging good signals (antennas pointed at the transmitters) with an out-of-phase messed up version of a signal (antennas pointed away from that very same signal). The end result is a ghosted, multi-pathed mess that generally is very hard for receivers to deal with.

whats happening with A-Channel HD OTA in Southern Ontario?

i looked at the FCC applications, and it looks like Achannel Barrie will be broadcasting at 14kW on 10.

will I be able to recieve that channel in Niagara. It's 90 miles away, and the other problem is that the tower isn't very high up.

my better hope was A-channel London, which according to the FCC website, will be broacasting digital on 57, at a generous 550kW

that signal should be very strong, so hopefully i'll be able to pick it up. Any news on how soon before A-Channel goes digital in London?

It's not actually in application yet; that's just what it's been temporarily assigned (for future planning). Since they haven't applied to the CRTC yet... it's many years off.

Although I was always hoping that since they are both CHUM stations, that CityHD would multicast for A-Channel in SD, and then eventually when A-Channel HD goes live, they can multicast CityHD.

I know multicast can hurt the PQ a bit, however once CKVR-DT begins to broadcast, it will lead to thsoe in Central Ontario to finally be able to get an ATSC signal, so it would make sense to have both going. Even today, would make sense being that A-Channel airs a lot of worthy shows, most notibly Leno.

Hey guys! Long time viewer, first time poster.

I live on the intersection of McLaughlin Rd and Steeles in Brampton, right on the border of Mississauga. I live a block away from Hurontario Rd, and just a five-minute walk away from Mavis Rd.

I get all of the Canadian and American channels easily, and those channels include FOX, PBS, ABC, CBS, CTV, CBC, CityTV, CBC RadioCanada, TBN, The CW, and SunTV. I get all of them at a steady 50 to 66%, with CBC being the only one that comes in at 85%.

However, my problem is with NBC. With my old antenna, the one that came with my HDTV Wonder, I could get NBC in a split second if I wanted to. Then that antenna broke because I was too rough with it while moving it around, and now with my new Zenith ZHDTV1, I can only get NBC if I place my antenna in specific spots, and with the wire spun around in different loops and positions. Otherwise, the signal can be as low as 4%, jumping around to 45% and 38%. When I do happen to get a good wire position, it stays at a steady 64%, but then after an hour, it starts to skip and just go back down again. This happens ALL TIME TIME, and it's really, really damn annoying...

All the other channels can be received at the same power as long as they're in the right spot -- it doesn't matter how the wire is looped around all over the place. But NBC has to be in one of four spots, with the wire going around a specific way, and the way is always different, it's not like I can duplicate what I did the last time to get NBC, because it just won't work. It may work the next day, or a few days later, but never consistently... Even with a shorter wire, it doesn't work better. I'm also using a 25db pre-amp, if that helps.

Why I am I having this problem with this new antenna? My old antenna was worse, sure, but at least I got NBC when I wanted it...

Any help will REALLY be appreciated. Thanks!

Just incase this information helps, I live in an apartment, on the fifth floor. The antenna is placed right beside my window, at about 1.5 meters above the ground, on top of my bookshelf.

NBC is the weakest signal of the three farthest away channels in South Buffalo. Perhaps you'll need to get a different antenna since your new one just isn't cutting it for the weaker stations.

Aww, that's too bad, because NBC is the network I watch the most, too... Law & Order, Law & Order: SVU, Law & Order: CI, The Office, Heroes, My Name is Earl, Studio 60, Dateline, etc. ...

I remembered that my old antenna was about 2.5 inches lower than this one is now, so I just lowered it 2.5 inches by taking it off its stand and putting it on a stack of books, and I'm getting a pretty steady 57% signal, and the wire is hanging off the back of my computer desk in a U-shape. This seems to work best for me when trying to get NBC, so I'll just use this wire-antenna location combination for NBC from now on.

Thanks for your advice. :)

don't forget CTV simucasts many shows that are on NBC, usually at or around the same time.

the problem with your setup now will be that you won't likely recieve NBC in when its raining out or maybe even windy days. Hopefully NBC will up their power sometime to make their station more reliable for those watching on indoor antennas in the GTA (although i have heard many people from Buffalo complain about NBC disapearing during weather too)
