I can reply on that antenna link with 1 word CRAP! our business has removed more of those pieces of S--- that i care to talk about. they are a cheap flimsy piece of junk. they dont even pick up the locals (within 5 miles) very well. In whitby area alot of the guests on her are telling you 4 bays etc. Dont forget their are alot of hi vhf channels out there in Rochester / buffalo and after transition Hamilton/ Toronto and Barrie. SO to put up a 4 bay would work and they can work on hi band but not very well. I would suggest a winegard or antennacraft model like the HBU series antennas. Thats whatwe sell here in the states and they work good on Canadian and buff and rochester. Otherwise the bowties are ok if you dont want all the channels. ALso consider a preamp. We always install them!
