Can anyone help shed some light on my following WNPI vs WNYF confusion?
I’m using rabbit ears (with UHF loop) in an Ottawa apartment (near Montfort hosp.) facing south (TVFool (http://www.tvfool.com/?option=com_wrapper&Itemid=29&q=id%3d9e748f5c86e0c3)). With my antenna turned / configured the right way I can tune in WCFE all the time, WNPI and WNYF most of the time except mid-day.
What’s strange to me is that I’m finding WNYF much easier to tune in than WNPI? I would expect it to be the other way around considering WNYF is weaker in power than WNPI. It appears they are both broadcast from the same physical location / antenna? Anyone else have the same experience?

A simple UHF loop has very little directivity, and thus is not immune to strong signals coming from Camp Fortune.

WNYF on 18 is adjacent to CITY on 17 from Herberts Crners
WNPI is adjacent to higher power stations on 22 (CBOFT) and 24 (TVO).

Next week, CHCH switches to channel 22 from Herberts Corners. Whether this help or hurts remains to be seen.

Fota, did you just get this behavior recently ? If you had a more directional antenna maybe it could help reduce co-channel interference you might be getting from the strong local channels SRC and TVO at 22&24. Pointing at WNPI/WNYF directly... Compare this to WNYF at 18 with channel 17 interference which is arrives with way lower power at your location. The flip side of this is when you get a more directional antenna, you might have trouble with WNYF, but I think it should actually help it too.

EDIT: tvlurker you beat me to it ! :D

Ok, thanks guys. Hadn't considered adjacent channels and their power. Will see what happens Sept. 1.
(flavoie: no, it's been like that pretty much since my new DTV install settled)

This is my tv fool plot regarding the pbs signal near HC tower. FLAVOIE

the Fortune tower is obstructed by height of land so Digital is a BIG improvement.
The view south has an elevation adnantage so at one time I could pick up
PBS with a sharpshooter 14 -40 UHF with no amplifier.

So I went and bought a cm4221HD for an attic mount installation, and got it set up over the weekend. I can pull in (in digital) CBC, Global (nice and strong too), Omni 1, Sun, TVO. Omni 1 is the weakest power of all those (around 38-45 reading on my tivo, but plenty good for a clear stutter free picture). City comes in some of the times, but Omni 2 doesn't at all.

I'm wondering what my next step should be as I want city to be more reliable, as well as being able to get omni2. Do I upgrade to the 4228 and put it on my roof, or try the cm 7777 pre amp. I'd hate to spend the money on the cm7777 only to have to go back later and get the 4228. Suggestions?

Also, this is with only a single connection off the antenna, and I am planning on splitting it multiple times (6?) in my final setup.

I'm also going to try the simple modifications to the 4221 (removing the plastic clips) to see if that improves anything.

Here is my tvfool report btw: http://www.tvfool.com/?option=com_wrapper&Itemid=29&q=id%3d9e7480e000d2c3

OMNI 2 is moving to 22 I believe on Sept 1st so don't worry about it.

Are you pointed at HC? If not point there and you should get 17 as well. If you split 6 times though I think you'll need a 7777.

I couldn't get 66 at all, not even a hint, added the 7777 and get about 75% strength.

jimlum, in my opinion, if you want a chance at WNPI, try a preamp.

slim_511, like wing mentioned, just turn your 4221hd towards HC. If you're splitting the signal that much, a preamp is a no brainer.

I've been trying to receive Global since last week, but its signal was weak and I was able to only receive it when I was standing right beside the antenna (can't explain... why...)

But the signal is coming in strong today. No digital artifacts and no "hicups". Anyone's signal also improved over the last day or two?

Hi all, just back from a couple weeks away and am now only getting static on TVO (24). I understand it changed to digital last week and I thought I would get perfect reception as I had quite good reception in analogue previously. Anyone else experiencing a similar situation? I have a basic 4-bay and tried moving the antenna to various positions but nothing. Thought it might be something with CF tower but I get CBC 4.1 and 9.1 and CTV 13, 30, 20.1, all fine, 40 OK. I've also always received 27.1 and 17. 1 from HC fine but never had anything from 66.1.

Anyway it is TVO that is my concern as that is really the only channel aside from CBC, OMNI, CTV and CITI that I care about.

Any thoughts?

Did you rescan?

Thanks lurker - that did it...never would have thought that I have to do that. Thanks to you knowledgeable vets for all your help !

jimlum, about your question about your delhi sharpshooter antenna, which looks like it's got a very good gain with the channels 14-30 range, if my experience is any guide, I could get a worse channel according to TVFool (WNYF at -7 or -8dB NM) with a preamp and my 4228hd, almost all the time, with my best tuner, the Hauppauge 950Q. At the channel for PBS - WNPI I assume, the gains of our antennas are similar, so you do have a shot at PBS with a preamp but also with a very good tuner. TVs usually have very good tuners, but keep this in mind, some are better than others. But it would need to be outdoors and with no obstructions if you take my experience as a guide.

replaced my vhf hi + channel 6 rabbit ears with VIP302SR
now get global @ 88% from 62%
previously had a bit of pixelation
now have none at all

however i now have more interference to my 91xg
OMNI1 dosent come in at all
and all uhf channels have about 10% less quality than before

it is connected to my cm7777 with seperate inputs

i get the same issue even if its not plugged in
it interferes just by physically being there
physically removing it corrects the issue

right now my 91xg and my 302sr only have about 1 foot vertical separation
would getting a longer mast pole and separating by at least 3 feet correct the issue?

please advise

charettepa, I think you got it right, it can be an antenna separation issue. 1- make sure the VHF antenna is below the UHF antenna. 2- check recommended separation (I can't give you advice for this but I bet somebody will chime in).

Curious, why does the VHF antenna have to be below the UHF one?

VHF antennas are typically mounted below the UHF one as VHF signals propagate further than UHF signals. Though in some circumstances, it is beneficial to have the VHF highest up the mast--for example, when you're trying to improve a very weak VHF station.

I received the A channel OTA signal on channel 43 perfectly up until recently. We no longer receive a signal on 43. (or 43.1 either) I heard on the news that A-Channel has become CTV2 and is being relaunched. Does anybody know if they will have a digital OTA signal or are they targeting the cable/satellite market for the CTV2 station? This affects all the A Stations across the province.

Doug

it's still working for me. They are going digital on the 31st.
