...a 4228 for Toronto and maybe a 4221 for Buffalo but need to figure out how I am going to mount them without one interfering with the other.Yaamon has a post earlier in this thread about mounting a 4221 with a 4228 so it can be done. My hunch is that you could probably mount them on the same mast with about 2 feet of space between them, but I could be wrong and you might have to experiment.

I dont see really why it would not work by pointing it in different direction but you might have to fine tune them in after.
I only had experience with the antenna being about 15' apart and that work perfectly.
What you would have to do is point the 4228 for the weakest Toronto station and then the smaller 4221 for Buffalo.
Then if you find that you lost any Toronto signal repeak the Toronto antenna and then check the signal of the Buffalo stations that they are still there.

So, I finally got around to getting my 4228.
I do want to try it in the attic, yes I know stampeder ;-) I'll try anyways.
It wont fit. So, I'm thinking of just popping the rivets off on one side and replacing back after with bolts.
Anybody against that procedure?

I'm thinking of just popping the rivets off on one side and replacing back after with bolts.That should work just fine, but in case you ever move it outside in the future I'd recommend galvanized nuts & bolts. Stainless steel nuts and bolts will not corrode but they're much softer metal so when they get old they can shear in heavy winds.

I've read somewhere that the CM9251A rotator set top box uses Pioneer's IR codes but I don't have proof of that. If its true, a person could use an IRBlaster to auto-rotate the antenna prior to a recording. For general viewing a Harmony remote can replicate the CM's remote control too.
Yes this is true. I set my Toshiba TV's remote when in Cable TV mode to use the Pioneer codes... sure enough it works the CM9251A rotor box!

In case anyone has followed!
Installing a CM 4228 in the attic, roughly pointed at the CN tower (I didnt even make any adjustements just pointed at where I thought it would be), in Woodbridge (GTA) gets me 10 or so digital channels.
I'm am very impressed with that antenna!

Congrats on your success. Mine has been up and down; the snow has caused havoc with my reception. On Monday, I had dropouts on FOXHD and that has never happened! Considering I'm in Mississauga with a roof mount, clear line of sight and a pre-amp, I'm stumped. In fact, I'm now considering buying a CM 9521a rotor. Can anyone recommend a local source or am I better off ordering from the US?

thought you guys/gals might enjoy seeing some pictures of an antenna project my partner and i are working on. We currently have a self-designed parabolic up approx. 100' on a R25G tower with a Yaesu 800 rotor. The new project is a Quad CM 2228 that is modified to improve feed design and will consist of 4 (32 Bay total) 4228s each with 7775 preamps. A BT BTY-HB-HP Hi-band VHF with a CM7777 will be below the bowties and will handle the VHF duties. On the UHF side, the 4 CM 2228 (Modified) each with 7775 Amps .. will have individual 7916 Belden downleads. This way we can stack in any manner we wish, by simple selecting the desired antenna(s) Performance was excellent on the parabolic and we are optimistic that this will exceed it.... We consistently lock on HD stations 100-175 miles. When we get this up, maybe i can share some data with you. Happy Holidays from East Texas.....

I was almost sold on the channel master 4242 but was turned off by it's size.
A local store recommended the CM 4228 - Much Smaller.
Will the CM 4228 get all the digital channels even though it's advertised as UHF only??
Will I get 2-13 ? Does this only receive digital HIDEF signals (I will not get the SD brodcasts?)
Do I need a rotor If I only want Detroit Stations? (45 KMS Northwest of me; Leamington, Ont)
Also - Can I mount this antenna in the attak (sp)??

Most of your questions are answered elsewhere in this form but may be hard to find, so i'll give you my opinion. :))
My CM 4228 pointed at buffalo and my 4221 both work great.
the 4228 is a high gain UHF antenna using 2 rows of 4 bowtie anatennas.
Its made for UHF TV, but because of the 2 rows it can pick up the high VHF (above ch.6) stations and FM very well. won't work so good for ch.2-5 (you need a very wide antenna for low VHF)
don't get confused with analog or digital. the anenna doesn't care and will pick up both.
I'm in Ajax and i get all the buffalo stations from ch 7 up, analog and digital.
Yes, it will work in the attic but better outside on a mast. the higher, the better.
I don't have a rotor. i combined 2 antennas to get T.O. & Buf stations.
Might be hard to get into the attic, i heard of someone on here who drilled out the rivets, took it apart and put it together again.

Here are some hard numbers for anyone on the fence about buying this antenna.
I live just north of Toronto in a high rise facing south, have a Sony 42A10 and (had) a RCA amplified indoor antenna hooked up. It could pick up 5.1, 9.1, 53.1 and 66.1 no problem, except the need to fine tune direction. Sometimes it would get 2.1, 4.1and rarely without dropouts, 43.1. Those required very fine aiming and gain adjustments. 5.1 and 9.1 had signal strength of 90 however the rest varied between 45 and 70 tops, with wide fluctuations. So I wasn't happy with it and came here looking for info.
Yesterday I bought a 4221 from Yaamon, and what an improvement! With the antenna pointing south, WUTV Fox 29.1, a high def channel I couldn't even get before with the RCA, is showing a signal strength of 98 :D Same with 2.1, 5.1 and 7.1. Channels 4.1, 23.1 and 43.1 are at 89, and 66.1 shows a 92 signal strength. These can be increased to 92-95 by pointing the antenna a bit east of south, at which point 29.1 and 2.1 drop from 98 to about 90. However with all these signal strengths being so strong, it really doesn't matter that much where its pointed!
Its not large, about 2 1/2 ft. high by 1 foot wide, very unobtrusive. I painted the centre pole grey and it blends into the building background. So don't make the same mistake as I did and spend money on the amplified RCA from Future Shop. If you really want one of those RCAs just PM me and you can pick it up for 5 bucks. ;)
How high is your antenna mounted?
2005-12-30, 07:31 PM
16 floors up, I have a building fairly close partially blocking the south view, I can see the top of the CN Tower, so an excellent location for those channels.
However given the distance, the building mentioned above (plus others further south), the curve of the earth/drop in height from up here to the lake, I was very surprised at those numbers for the Buffalo stations. A signal strength of 70+ should be OK for their HD, so its likely the numbers would be quite acceptable in lower locations.

Bill, I would like to see your photos but this links not working anymore.

I think its just a terminology problem here. A stacked configuration is 2 identical Bowtie Reflector antennas mounted one on top of the other in the exact same direction... I just stacked two 4228 antennas. With alot of trial and error I finally got it to work right. I am getting alot more stations then I did before. I was wondering how many people have had any success with doing this?
