I live in a house in East York (Toronto). I have been using until now a standard indoor rabbit ear antenna (2 poles, plus a circle) on my TV (through my VCR) and was able to get about 6 channels: CTV, CBC, Global, Sun TV, City TV, OMNI 1 and 2 and TVO, with a quality that ranges from excellent (CTV) to just barely acceptable, even when fiddling with the antenna. More importantly, recently (past few weeks), I haven't been able to receive CBC-Radio Canada (Channel 25) anymore, or very very poorly (unwatchable). I am looking to buy a new antenna (would prefer indoor as I don't have anyone who can help with outdoor installation) but I am completely lost as to what to buy to get a better reception. Also, with a different type antenna, could I get additional channels? Is outdoor antenna worth the trouble?
Any help would be greatly appreciated!!

Many thanks!
