Hi Laurent, I do and don't get those two stations... I have a Digiwave antenna on the roof (Verdun) hooked up to both my TV and to a Tablo DVR. 3-1, 3-2, 3-3, 3-4, 5-1 and 5-3 are all received on my Tablo. However, I have lost all 3-1 to 3-4 on my TV. I have lost these since they moved from 22 to 20 and I can't tune them anymore, either by rescanning or entering them manually with the remote.

WCAX and WPTZ are sharing a temporary antenna. I quote Tower Guy who is a retired TV engineer from NY:
Tower Guy said:
WCAX/WPTZ are sharing a TFU-16WB antenna. The gain is similar to the burnt out antenna. The power handling is slightly lower. It is directional with less power toward the northeast.

This is a signal report for Verdun from rabbitears.info:

This image is an extract from that report:



The WCAX temporary antenna is very directional and lower on another tower. It is only sending 27 kW ERP in your direction:

I also notice a weaker signal for WCAX and WPTZ here in Swanton, VT which is in the same path as Montreal - to - Mt. Mansfield. I get some random pixelation, but otherwise it's still a pretty decent signal.

That being said, it's not nearly as bad as me trying to pull CJNT out of the air down here :(

Thanks for all the info but I don't think this is a transmitter issue. When WCAX switched from 22 to 20, I lost it on both the two devices linked to my antenna, a TV and a Tablo DVR.

Following the change, I rescanned both the TV and the Tablo and only Tablo picked up the signal. For now, I blame it on my "old" TV and its limited features. Not a big problem actually, since most of the content I watch is recorded with the Tablo.

It shouldn't be It shouldn't be a TV 'feature' issue, but WCAX being on RF20 now puts it right in between CBFT RF19 and CBMT RF21 (I might have these reversed). It's quite possible the TV's built-in tuner is not as great at rejecting interference from strong adjacent signals.

Are you receiving WPTZ still? It didn't move from RF14, but it is radiating from the same exact antenna.

WPTZ and WCAX are both transmitting at reduced power from a directional antenna with a slightly different pattern than what WPTZ was using previously.
Both WCAX and WPTZ are tranmsitting with a directional pattern, unlike before where WCAX was omnidirectional and WPTZ had a deep null towards Sherbrooke.
(And because of the "nose" of the mountain which shielded both signals from a large swath of the Townships)

Confirmed in Sherbrooke, both WCAX and WPTZ were fairly easy to receive before the tower fire with 27 and 21 dB SNR respectively. Now, I sparsely get WCAX with a very low 16 dB SNR and I never have WPTZ. SNR is 13 dB on the latter one and no tropospheric conditions can improve it.

I use a vertically stack of 2 x 4228HD in my attic. I have no idea what I could do to improve further more my antenna gain. I guess it means no Superbowl party for me on next February.

It doesn't look promising for you. I don't know your exact location, but this is a report from rabbitears.info for Sherbrooke City Hall:
https://www.rabbitears.info/searchmap.php?request=result&study_id=34963

The Special Temporary Authority expires 06/04/2020, so they will probably wait for warmer weather to do antenna work:
https://www.rabbitears.info/tvq.php?request=items&facid=46728

Sherbrooke is in a null of the transmitting antenna pattern with less than 2 kW being sent in your direction:



About all you can do is try a different feed method if you have already tried different attic locations and can't go outside.

Another idea would be to build an antenna designed for max gain at channel 20. Most of the antennas currently available have less gain at the low end of UHF.

Thanks to rabbit73 and everyone else for your replies. I am glad to hear that I am not alone. Although I am happy to report that the signal seems to have improved since my original post 11 days ago. I can even get 3-2, 3-3 and 3-4 if the weather conditions are OK. But it is still not as good as before the antenna fire.

FYI, I am in the West Island of Montreal (Dollard-des-Ormeaux). This is my TVFool report for my location, FWIW:

Hello,
I no longer receive ME TV, PBS , etc. from Burlington and Plattsburgh here in Pieerefonds, Montreal.
Anybody else have this problem ?
Is it because of the fire on Mt. Mansfield last December, 2019?
Thanks,
Bill

PBS(s) still working for me in South Shore Montreal (you didn't say which one) 33.x and 57.x. Nothing has changed on their end (if you read this after July 2nd, 57.x changed frequencies, rescan your tv).

I rarely get 5.x, but strangely I get 3.x around 40%. This is due to the tower fire and temporary antenna they mounted in winter 2019. Antenna to be back to normal around August 2020, the antenna is so heavy they need special helicopters that are difficult to book due to the current world circumstances.

Also of note 44.x and 57.x has to change frequencies by July 3rd (57.x said July 2nd on Twitter).

As of 10:47 friday 31 july ABC, CBS, NBC & FOX are off the air.
The 2 PBS are on.
Things are happening on Mount Mansfield...

Cheers

Interesting to watch and see how fast they removed the old antennas and airlifted the new ones. Impressive work.
Reminded me a little bit on how I installed my 35ft tower 40 yrs ago alone: I would install each section and climb up on each section and bring up the remaining section and bolt it in place.

The new WFF/WVNY look great by the way. Visually they looked different in sizes. I would have to check that.

Looking forward to the new signals later today.

For reference, before the Aug 1st installation:
WVNY: signal strength was 100 and signal quality was 81
WFFF: signal strength was 66 and signal quality was 50

Cheers,

Well guys, did not expect those results.
As of now I get almost the same signal strength from WVNY and WFFF. Respectively 75% and 50%.
The big question: are they using the new antennas?

Will have to wait and see

Cheers,

Here is your answer:

While the new antenna is now installed, we’re not broadcasting over the air with it just yet. New transmission lines are being custom-made to fit the antenna. Crews need to work on the tower tomorrow, Monday and Tuesday, from 9 AM to 4 PM each day. In order to allow for that work, our over-the air signal will be unavailable during those times.

Hi guys,

This is my first post and I hope you will be patient with me.
My postal code is J3Y 0L1, I am located in South-Shore of Montreal (St-Hubert, Quebec).
I currently use an RCA indoor antenna and I'm getting around 12 OTA channels (including few american channels).
I'm planning to install an outdoor antenna inside the attic + signal booster so I can get 20channels or more.
Can you please tell me which antenna and which signal booster is best for my situation?
I was hesitating between these two antennad, based on their reviews:



The elevation will be around 25ft. There are no trees and no big buildings around my house.

This is my TVFool report:

Thank you!
