Did a 50 ft trimming with my 100/ft/attic/4221 setup. not too much change at the signal power level. must be my attic deflection. I would like to get a hand on a preamp to give it a try. I just afraid that would overly max out power on my cbc which coming strong at 98% right now.
Had my Channel Master 4221 roof installed last week. So far the results are not much different from when I had it in my attic (from January 2007 - September 2007). NBC (channel 2-1) and CBS (channel 4-1) are cutting in and out (most other channels are reliable).
The RG6 cable run from my roof to the basement is about 50ft. From there, it's connected to an in-line amp (RCA 10db) then another 45ft to the TV.
I tried using a Channel Master 7777 pre-amp (without the in-line amp) but the signal seemed to be worse.
I'd like a more reliable signal from NBC and CBS - should I change the CM 4221 to a 4228?

dfex, that is weird as I did a friend antenna almost two years ago same location behind the shell gas station no preamp or booster and he gets Nbc and Cbs no problem.
The cable who did the connectors. Hope they did not strip off the braided ground wire?
V&E Antenna did the installation and they appear to have done it right - as CBC and all the other channels come in pretty strong. I think I'll try going up and tweaking the direction. If that doesn't work should I try a CM 4228?

Maybe you need to repeak it as in your area a 4221 get all the stations. Repeak for Nbc and Fox.
Try and repeak first and if you did not get better results a 4228 is a little stronger.
I'm not sure if I can raise the antenna any higher (it's almost at the top of the mast). I get a pretty strong and reliable signal from Fox but not so much from NBC. Is NBC East or West of the CN Tower?
The guys from V&E Antenna said I have a clear sight of the CN Tower (he said he can almost see the bottom of the CN Tower from my roof).

Yaamon means re-aim your antenna (repeaking is the term for that) so try his suggestion and see how turning it works out. :)

dfex, stampeder understands Jamaican he knows what I meant by repeaking. :p
If V & E position your antenna towards the Cn tower then thats is the problem. They should be more than experienced to know that to get from you location Nbc, Cbs and Abc you DO NOT point it towars the Cn tower.
From you location it points away from the Cn tower atowards 160-165' on a compass.
Before I do any install I look on a map for each location so I have a idea of where to point the antenna. I start from there and peak the signal for Nbc and Fox with my meter.
So if you are going on to the roof that means you stand behind the antenna and move the antenna maybe 1/4" on the pole towards east.
Close to your location south west corner of Major Mac and Woodbine look at where the 4221 I installed is pointing with a compass you should be pointing towards that direction and away from the Cn tower.
Like I said adjust for equal signal bewteen Nbc and Fox.
Thanks for the tip - I'll try to get up there this weekend. I'll bring the camera up and try to get some pictures as well.

I'd like to install 4228 BUT I don't have any experience, anyone can share? or maybe we can help each other.
I have a samsung 260H, and a Philips MAN510 in door antenna, and I am getting:
what are my chances of using outdoor 4228 or 4221? my family room is facing north.
2007-10-14, 04:52 PM
You need to mount the antenna outside a 4221 or 4228 will work well. Once its mounted use a compass and start off by pointing towards 165' and peak the signal bewteen Nbc and Fox for equal signal strength.
If you have a chimney I would recommend you mount the antenna there with a clear view south. You can buy a pair of chimney brackets they are not expensive.
Remember you need to ground the antenna and coax line.
I hope you are not close to the north east side of Warden and Hwy 7 as I think they are building a huge condo on Hwy 7 east of Warden.
All you need to install is access to a hammer drill and long masonary bit and RG6 cable. Remember to drill into the brick itself.

Thanks for your fast reply.
there is also a 4248, so out of the three (4221, 4228 and 4248) which one is the best one?
Yes, unfortunately, I am very close to warden (north east corner of hwy 7 and warden). will the condo (besides Motorola) block the view?
Yes, I will mount it on my chimney. Where can I buy the chimney brackets? I also don't have the antenna yet :-) where can I find them in GTA? besides the chimney brackets, what else do I need? is there any instructions available on mounting the antenna on the chimney?

The 4221 or 4228 is a better antenna than the 4248 from chan 14 to 60 where we watch amlost all the channels.
Is the Motorola building you are talking about not at 407 and Warden that building is not a problem. I was not aware Motorola was going to be on Hwy 7 too?
If the condos that they are building on Hwy 7 and east of Warden will be blocking your south view you will have problems receiving the Buffalo channels.
There are vendors listed on this board that is close to you. There are no real instructions inside the box on how to install the antenna. If you are not a handy person and don't have access to the proper tools it might be time consuming and fustrating.
You need tomake sure that the coax cable is striped and the connectors are installed propelry etc.

Thanks. I was talking about the Motorola building just 100 meter north of 407.
I thought you were talking about the condos/townhomes south of hwy7 and north of 407.
I am not aware of condos north of hwy 7/east of warden. I do know one that just east of future shop, are you talking about that one? I think that one is not too high.
I am a bit concerned about the land around village parkway blvd, are they going to be new condos?
I am not a experienced handy man, but I do have limited experiences... but anyways, thanks for your reply!

Hi I was referring to the building east of Future shop and it will surely be higher than a two story house enough that if you are close by will greatly affect reception.
Depending on where your house is if your view is clear of that new building you will be ok.

I am pretty much exactly where you are. I tested the signals a couple months ago with a home made 4221 antenna (see Posts #322 -> 325). I was able to recieve all the Toronto stations (except for SUN which was just under the threshold of getting the picture). I am pretty much just behind that new condo by FS (It's actually not that big). At the time I tested it they didn't have that crown thing lining top of the building put up so I don't know how much more that will affect it. By my guestimation it only added about 3-4 meters to the height of the building.
They are also building that Downtown Markham junk around the Motorola building. Im pretty sure there will probably be buildings at least equal or taller than Motorola. I can't really see the Motorola building from my third floor though. I think right now the Hilton is probably more of a problem than anything for anybody in the north east corner of 7 and warden. From where I am it is partially blocking the view towards the CN Tower.
Hopefully Downtown Markham doesn't go too high cause that could be like a giant wall in front of the Buffalo stations and anything else to the south.
Yaamon - I'm thinking of changing my CM 4221 to a CM 4228. I think I read somewhere that the CM 4221 catches a wider signal than the 4228. Does this mean I could lose channels if I go with the 4228 over the 4221?
2007-10-15, 12:31 AM
dfex, from your location the coverage of a 4228 will be fine for the stations from the cn tower and Buffalo area.
2007-10-18, 01:35 AM
I live in the mccowan 16th area. i want to ask if anyone has a silver sensor and what channels are you receiving. I am really looking for the Canadian channels and maybe one or two buffalo channels, i will be putting this on the second floor facing directly south on the 2nd floor and a bungalow directly across from me.
2007-10-18, 12:10 PM
sytheman, you should get most of the Toronto channels from a 2nd story facing south.
Also with some luck cw23 and Pbs too and maybe Cbs.
