I currently have a 4 bay antenna, although I'm quite pleased with my reception in Toronto. However, thinking things can always improve, I've just bought an 8 Bay multidirectional antenna (Digiwave 7287) that has the ability to rotate its two sides towards each other. However, there were no instructions regarding how much to angle the two sides towards each other. Would I position each bay to face each of the two primary transmitters (e.g. CN Tower and Grand Island) or just leave it flat without angling the bays, essentially just doubling the surface area from my old antenna?
Many thanks for your input.

Welcome. The funny thing is with digital it does not matter how much you improve it since the PQ and AQ is going to stay the same. Talk to the vendor or the manufacturer they might have information that at least I am not aware of.

The best case scenario by stacking 2 equal antennas in the same direction is to improve gain by close to 3 dB or in other words double the power level. Theory regarding combining antennas in different directions is quite complicated and practically hardly ever used. Any phase shifting will compromise the result signal rather than help. Two signals coming from different directions will more likely be out of phase therefore the end result will be a reduced signal. But heck , what do I know, like I said maybe the vendor/manufacturer combo knows better.

They essentially are reliaying on the trial and error capabilities of their customers and the fact that in most markets there are not too many digital TV stations and more likely there are a few that at least you are not going to be interested in. Maybe you are lucky to point them in a way that the Stations heavily affected do not interest you , and the rest of the pack although it gets affected , at least not to the point to loose signal.

The pro advice would be to have a rotor with a single antenna rather than this monster or frankenstein creation. Funny that only chineese are bulding this ones while the major antenna historical manufacturers have none of this. I just wonder why eh?

Or, as usual, maybe I am wrong? ........

Wow, thanks for the input.
I'm hoping the upgrade will result in more reliability in heavy weather as opposed to better picture as there are a couple of US stations that I receive at 1-2 "bars" of "signal strength" on my TV. I'm hoping I can stop those stations from being dropped in heavy weather.
As far as installing the antenna, my plan is to: 1) initially install it without angling the bays toward each other and just rotate the flat antenna on its rooftop mast until I get the best signal strength and then 2) angle the 2 bays toward each other to see if signal strength improves.

You may have better luck aiming the bays away from each other as opposed to aiming them towards each other. Hope that makes sense.. . And, as HD Fan pointed out, this antenna, as novel as it looks and is designed, is basically a "crapshot". I can see what the designer was thinking when they put this product out, but when you start "pointing the bays", you add or subtract to the incoming signal. If you have time on your hands and are willing to experiment, you just might get this antenna to work for you. Start by aiming the bays as you stated (one @ CN Tower, other at GI) and work from there. Good luck.. .

I had the Digiwave CM4221 clone and was able to get all the US stations but not the Canadian except for CBC so switched to the same antenna you have. One antenna is pointed in the same direction as my previous CM4221 clone and the other at an angle to hit the CN Tower. It brings in some of the Canadian channels but not in high def and I assume they not digital as the image is pretty poor with a lot of snow.

I think this is more of a reflection of the Canadian signals being weak than the antenna being of poor design.

Or it could be the standard problem with trying to combine two antennas pointing in different directions. It can work, or it can make things worse.

See rjdto's postings. I get 18+ HD channels near the broadview subway.

I wonder, I am new at all this, and thinking of what I want at some point myself.  From Toronto, Buffalo is almost straight south, from where I am in the city, so is the CN Tower :).  That's where my rather crudely built antenna is pointing, works well for the Toronto stations, but lousy for the Buffalo ones.  I think I need to talk to my landlord about putting the antenna up higher.  Either on the chimney or the roof.  I might need to build an enclosure for it though.    Pardon me, I am rambling.

However if I want Hamilton it's much more west then south, so I would use a second antenna pointed at Hamilton, maybe attached to the West side of that same chimney.  Then put a Coax A-B switch where the 2 cables come into the house, so I can switch between the 2 4 bay antennas.  Once each antenna is tuned, it stays the way it is.     Probably much cheaper and easier then trying to rotate a single 4 bay antenna, since it only really needs 2 directions.

Sounds like your onto something wogster! I wish you luck with your landlord.. . :-)

I have a long range vhf/uhf antenna, being from just north of toronto, I first pointed the antenna line of sight to the CN Tower and Grand Island NY. When I scanned the channels I was only able to receive some Toronto Channels and No buffalo channels. So What I did was rotate the antenna away from the CN Tower and pointed the antenna towards just east of Buffalo near the WGRZ tower. There I was able to receive all the local channels because of the high powerful strenght of the CN Tower and having a long range antenna I was able to recieve to my astonishment all the Buffalo Channels, Including WIVB which I hear is the hardest buffalo channel to pick up and I am over 95 Miles from the transmitter.

hello acyyz58 what type of setup are you using? i'm trying to pull in the buffalo stations too. was able to get WIVB with a four bay plus a 28dB amp but not the NBC, ABC, FOX or PBS. these are all in the same direction, some farther than others
