I wasn't aware that Orion sold Channel Master products. Interesting. Also interesting that you've managed to capture 10.1 (CFPL London, CTV2, RF10) with an indoor UHF antenna. It's about the furthest receivable VHF station from here. Good stuff.

Yes, a rooftop installation is definitely recommended. If it's within your budget, a rotator is also recommended to tweak signals.

Default Results - CBC?

Hi, new to the forum, so apologize in advance if question has already been asked many times (75 pages is a lot to go through).

I am in Keats Way & Erbsville area of Waterloo.

I have a DIY 4-bay DB4 style antenna and pre-amp installed in attic.

Best results so far have been pointing at Toronto where I get:
13-1 (Kitchener)
31-1 (City - Toronto)
41-1 (Global - Toronto)
47-1 (OMNI - Toronto)

Any idea why I can't seem to get 5-1 CBC at all? Seems with TV Fool details (below) and others results, I should be able to get this channel if I can get these others from Toronto.

Any tips would be appreciated.

jmccrack650, welcome to the forums!

31.1 (RF 31) is actually coming from Woodstock.

CBC Toronto (CBLT, RF 20), is a strong station. Though it could be that your antenna's gain isn't as good lower down in the UHF band on channel 20.

Default downtown Kitchener - attic vs mast? with trees?

Hi
Thanks for this useful forum. I am finally getting around to getting a new antenna setup at home after the digital transition.
I am located at King & Stirling area, downtown Kitchener, in a 2-storey house.

My question is whether it would be worth my effort (in terms of extra stations) to move my antenna from inside the attic to the roof. It is a bit of an effort, but do see a way of getting a 5-ft mast mounted to the top of the roof. Of course, a rotor is in question as well, but this all needs to be worth the effort, as I would have to mount it, and add all the wiring connections for signal, ground and (if applicable), the rotor wiring.

In my attic, I have an Antennas Direct ClearStream 4 antenna, with a CM7777preamp. With this setup, I get nice, strong reception on
6 - Global
13 - CKCO
28 - TVO
29 (analog) CBC (though a bit grainy)
61 (analog) CBC-french (also a bit grainy, but I don't really watch this station)

I did a quick 'balancing' act on the roof, and I will then get 31-CITY with strong signal, but it is entirely blocked out in the attic.

The main reason for my question: there are some big trees across the street from us (it woud be about 50 feet away, they are in the front yards of houses across the road). That puts them right in the Hamilton direction from us. I am pretty sure that some of the forum readers have had experience with this.

As I said, I am curious about whether the work/cost is worth it. If i were to only get CITY and a repeat of Global (on 41) and CTV (on 9), it would not be....but if it would also add CTV2 (10) or Hamilton stations, it would be. (I don't think I have much hope of getting Buffalo, in any event).

Any thoughts? (though I may try it out anyway).

Thanks

sparky640000, I'm near Greenbrook and Stirling. And while I have a 68' tower, my antenna does face into high evergreen trees in the direction of London. Yet I get great signal from CTV2 (CFPL, RF 10) London.

Note that I do have a VHF antenna (Antennas Direct C5), and you would likely require one yourself to have success with CFPL London. But I do believe you stand a good chance of receiving this station with a roof top install. And perhaps with a good VHF attic antenna.

Before investing in a VHF antenna, I would check one thing: Is the internal switch on the CM7777 set to "combined"? If not, try this...as it will combine VHF signals with your UHF antenna feed.

Either way, a rotator is recommended. There is enough of a difference in direction from London, Hamilton, and Toronto that a direction change is required on the antenna.

Visit www.tvfool.com for a reception report on your address. This website also offers a tool that draws lines from the transmitters to your location on a map....allowing you to visualize the signal path to see what lies between you and the signal.

Good luck!

Default King/Stirling & trees

Hi Jase88,
Thanks very much for your comments. Indeed, last weekend, I was playing with the switch on the CM7777--->as you were saying, it does have an impact on VHF channels,. Setting the switch to 'combined' allows me to pick up a strong signal on 6.1/6.2 (Global) from my in-attic installation, which is totally absent when the switch is on uhf-only.
We are actually on top of a hill facing in the London direction, so there is some hope of cfpl/london, though I do expect that I won't know for sure until I try it out.
Fortunately, I believe the former owner of our house had an antenna setup at some point...there is a crossbar that has been mounted just below the tip of our (sharp) roof, and that is easily accessible from a step-ladder from a 2nd floor balcony. And, there is a ground rod already pounded into the ground, near the old window that I intend to route the cables into the house from. So, a lot of the heavy physical work is already done for me in advance.
Anyway, I'll try it out, probably when the weather gets a little less icy (don't want to slip off the ladder, after all).
There is hope for improvement anyway, and this is an interesting exercise to try out.
As a sidebar....when I first moved into the area, back in the mid-90s, Rogers was in the middle of providing a 'reverse-option' cable, where they would jack up peoples' cable bills for extra channels unless the customer actively opted-out. Because of this, I vowed never to go to cable again. Up to now, rabbit-ears have been good enough, but with the digital transition, I now know I can do much better.
Finally, I have been seeing a bit of a supply problem with getting rotors these days. I'll have to check the store again (I have been going to Research Electronics, in the N end of Waterloo; it is about a block from where I work).
Thanks for your advice and work in helping people out in this forum! I'll post again with results when I have it all set up (probably later in the spring some time).
Cheers

Default PS, re: tvfool

PS: Indeed I am aware and have used TVfool. Using the directional diagram, in conjunction with the map and satellite images from google maps does indeed help in getting your bearings.

Yes, you do tend to see some sort of antenna installation or hardware on many of the older homes in the area. I'm sure I've even seen a couple TV towers on the hill around your home--I pass by there all of the time.

Once you get set up with a UHF antenna on the roof, I would try just pointing it at Toronto, and with a VHF at London (basically 180° apart). This may afford you reception of a satisfactory number of channels without the need of a rotator (though I still believe a rotator is the best option). Most Toronto stations are sufficiently powerful enough post-transition that a simple rooftop setup here in Kitchener may work well.

And yes, "negative option billing" is still something many people here in KW remember well.

Default CM 4228HD hack

Hello forum, I'm a OTA neophyte watching your site for months and as helpful as you've been I'm clueless reading the instructions to modify my antenna. I'd love to meet up with anyone in the Stanley Park area of Kitchener with these skills.

Wow this forum is huge.

Can anyone recommend good installers for Cambridge?

I'm not looking to skimp out on quality. I want to try to get as many US and cn tower channels as possible without a rotor. Maybe even stack 2 identical antennas if I have to.

TIA

HI,

I am looking for some advice to maximize my reception, with a couple of conditions.
1) It has to be an attic setup and 2) No rotator. 3) I want to add Buffalo stations

Here is my TVFool: http://www.tvfool.com/?option=com_wr...40334260635ee3

As you can see, I am smack dab in the middle of a number of towers.

I first built a DIY 4 bay 4221 Clone two years ago. I have it pointing between Toronto and Hamilton. I have a SBGH build with tinfoil reflector pointed between Paris and Kitchener. Both are ganged by a 2:1 splitter feeding into a CM7777. From the output I am feeding 4 TVs, an ATSC Tuner card in a HTPC and a HDHomeRun.
I have built a “better” build of the SBGH using 300ohm’s design from 2008.
I want a third antenna pointing towards Buffalo.

The following are my readings using the meter in the HDHomeRun. My antennas are in my attic.

Readings – Morning March 12
4221 Clone

Channel Strength
11 CHCH 87
19 TVO 96
20 CBC 82

SBGH – Pointed between Kitchener and Paris
6 Global 99
10 CTV 76
13 CTV 94
28 TVO 92
31 City 82
36 CITS 84

SBGH – Pointed to Buffalo
33 NBC 61
38 ABC 73
39 CBS 68
7 MeTV 47
43 PBS 60
I haven’t played with the antenna pointed towards Buffalo since, so I don’t know if weather was a factor or not. It was a nice day.


Readings – Evening March 21
4221 Clone

Channel Strength
9 CFTO 69
11 CHCH 86
19 TVO 96
20 CBC 97
41 Global 81
44 City 74
47 CFMT 75 - 80 00

SBGH6 Global 95
10 CTV 81
13 CTV 94
22 FOX (Erie) 67 - 70
28 TVO 90
31 City 85
36 CITS 80


1) Do I have the right antennas?
2) I have the parts to turn my SBGH (new build) into a DBGH with mesh reflector.
3) How do I gang three antenna’s together? Two splitters, or one 3:1

The SBGH appears to be doing far better than what I'd expect from an attic install in Cambridge. A DBGH might improve on that somewhat.

Unfortunately the warm weather conditions have made Buffalo reception results unpredictable this month.

Default Attic Install - Greenfield/Traynor Area

No doubt a challenging area with lots of high-rise buildings, and the home itself only a bungalow.

TV Fool Report

With only a very directional high-gain VHF antenna (the Wade-Delhi VIP307SR), an 8dB-gain drop amp, and about 30' of RG6, I was able to receive the following:

CIII; Global; RF 6; Paris; 100%
CKCO; CTV; RF 13; Baden (Kitchener); 100%
CICA; TVO; RF 28; Paris; 70%
CFPL; CTV2; RF 10; London; 70%

With a UHF antenna, we hope to get CITY TV Woodstock, and maybe some of the stronger Toronto stations.

Is that your old one Jase?
How did manage that into an attic?
