Is your indoor antenna UHF/VHF? Would be fun to test your antenna in the Attic (Has high has you can) and compare with the result you had at the second floor.(If you have time...).

My guess is that you will see a big improvement.
I did give that a try last week end, and it did not really change anything on the digital Mount Mansfield channels. Still can't get WFFF-DT :(

WCFE-DT and american analog channels had clearly better reception though.

Climbing in the attic probably raised the antenna by about 8-10 feet. I only tried a single location, and roughly aimed the antenna. I did not take the time to venture in every spot and aim for the best reception in various locations.

Kro, I saw in another thread that you've ordered a Channel Master 4221:

I also bought it from them (www.sensuz.com) ...
Have you installed it yet? How good of a reception do you get with this antenna at your location? How strong is WFFF-DT?

Are you able to receive all digital stations from Montreal, Mansfield and Lyon mountain without rotating the antenna?

Thanks!

My New Antennas Are Installed Now

I install my new Channel Master 4221 and a VHF antenna (Delhi ZIP-8) in my attic. The antenna are about 38' from the groud and nothing is blocking my view and elevation (Google eart) is 175'. My tuner is an LG Fifth Generation. The antennas are join using a UFH/VHF combiner splitter (Is there a better way?).

Result:
DT:
2.1 (SRC) 95%-100%
3.1 (CBS) 95 %-100%
5.1 (NBC) 95%-100%
6.1 (CBC) 75%-80%
22.1 (ABC) 70%
33.1 (PBS) 100%
44.1 (FOX) 75%-80%
57.1 (PBS) 80%

Analog:
2, 6, 12 (10/10)
5 (5/10)
7 (7/10)
8 (7/10)

17, 22, 29, 35, 46, 62 (10/10)
24, 27, 30 (6/10)
44 ?? Co-Channel!??
52 (2/10)

Ok analog is usefull for me for the other TV's and for recording, the only glitch is I get a Co-channel on 44 (Other wise I think it would have a 10/10). I tried to find from where (Another 44 analog channel) but I did not find anything. Any idea?

Are you able to receive all digital stations from Montreal, Mansfield and Lyon mountain without rotating the antenna?
Yes.

Question: I'm not sure what you mean by "co-channel". When you do a channel scan you get 44.1 in digital (FOX) but you also get an analogue station on 44, or is it a digital sub-channel like 44.2?

44.1 in digital (FOX) is ok no problem it's 44 analog on which I see another channel at the same time (Look more like ghost of another channel).

Are you using a PreAmp to get those results in your attic? I recall you mentioning a CM7777 from Sensuz a while back...

in Ste-Dorothee too

That sounds strange since WETK WCAX and WPTZ are coming form EXACTLY the same location. Mountain Lake is further wo the west. I am at Samson & Bord de L'Eau and luckily have no house blocking my system, but regardless of what I do I cannot get FOX. I look forward to hearing what results you have when you hook up the preamp.

I am in Ste-Dorothee too, just down on Bord-de-l'eau from the junction with Samson, I cannot get FOX either...

Also, to get DT channels below 13, do I need a VHF antenna or my 4228 is enough? I do not seem to be able to get a lock on channels below 12.1
Do you have a preamp ? My antenna is in the attic...

For now, I get CBFT-DT(SRC), CBMT-DT(CBC), WCFE(PBS), VPT, WPTZ(is that ABC? can't remember)...

A CM4228 is very good on channels 7 to 13 VHF. A UHF-only preamp will ruin that, but a UHF/VHF preamp will give what you need.

To Momotte:
Remember that the digital channel number (like 5.1) is not necessarily related to the actual frequency being used... the perfect example is Ch 5 (WPTZ, NBC) which is actullay broadcasting on UHF ch 14 (but appears as 5.1 and 5.2).
I believe in this area the only VHF digital channel being broadcast is Ch 22 (analog) which is now broadcasting digital on VHF 13... I am trold that the 4228 will cover that frequency... there are some posters on this board that seem to be getting CH 13 with that antenna... I am using a 4 bay bowtie and I get zip.... even WPTZ and WFFF are marginal depending on the weather... if you are getting WPTZ (with its poor signal) you should get WCAX (3.1 and 3.2) as well.
I would like to see your installation...you cannot be too far from me... I am at the dead end of the dead end of Place des Rapides.

Remapping and PSIP Data

Remember that the digital channel number (like 5.1) is not necessarily related to the actual frequency being used... the perfect example is Ch 5 (WPTZ, NBC) which is actullay broadcasting on UHF ch 14 (but appears as 5.1 and 5.2).
Yes that's a very important point about Digital OTA. It is called "remapping" and it is done with PSIP data. The OTA Forum Knowledge Base & FAQ explains both.

In the case above, we say that Channel 14.1 remaps to 5.1 while 14.2 remaps to 5.2 and on and on... only Digital OTA does remapping and PSIP. Someday when analogue is shut down it will be much simpler for consumers to remember! :D

You maybe right it look like Adjacent Channel Interference
see fig 11-4 and 11.5 (http://www.pctinternational.com/channelmaster/prev/_pdfs/guide_AntennaInstallation.pdf) i'm experiencing both at the same time .

I was not thinking about that because 46 is so low power that it's more difficult to receive than 22 analog.
I checked yesterday and it's SRC! But I cannot find from where it would be broadcast... Let's assume it's comming from the back would putting aluminum foil on the back of my CM4221 would help? I will try it this week-end see if it has any effect on anything.

Stampeder... a quick question... can the weather have a severe effect on UHF reception.... there are times when a signal is 90%, then drops to 71%. I am using an EVU 9200 so the signal strength meter does not register below about 55%...a real problem. It seems that WPTZ and WFFF 5.x and 44.x) drop out all the way to zero... while WCAX and Vermont ETV (3.x and 33.x) just show a signal drop.
I assume that 5.x and 44.x are still having problems or running at reduced power, since all these stations come from the same location. Any thoughts?
I have chaged the balun, rerouted the 300 ohm from the terminals to the balun to avoid metal, etc.... all on a Philips / Gemini 1483 4 bay bowtie.
Tnx.

Yes, rain and snow can cause signal loss, but in the winter there is also a bit of a rise because trees have lost their leaves. In the case of Burlington stations they are booming north from a mountain valley so if a storm is moving through that valley there might be some signal changes. Generally a preamp will eliminate most of those problems.

You could find it on www.wade-antenna.com But there's no gain chart...(Nothing usefull). Anyway I would not recommand it unless your in my situation.(Attic installation and I need Analog Low VHF for the other TV's). I would much more recommand a channel cut to VHF 13, 11 elements (There's also a 5 elements if space is a concern) you can have it at raybel they cost less than 100$ (If i remember well it's 65$ and 85$)

What do you mean? The CM-4221 (UHF) and the Delhi (VHF) are join together using a UFH/VHF combiner. The loss is impercetible for UHF (I did not try the VHF alone).

That's a good idea because it will reject local VHF signals, but if you buy a single cut antenna you might have to wait for delivery for it.

If your location is not bothered by VHF channel interference from the local stations you can buy a VHF/FM and get one much easier and you will also get FM radio stations from Vermont too for years and years to come.

Its up to the consumer though. People in Montreal have had serious problems with the local VHF stations.
