Railfan Scanning

Well, I received my Traintenna LP but I haven't had much luck in getting it going. Well, by that I mean it seems to be working but it doesn't pick up any better than my VHF antenna from RadioShack. I'm don't think I have anything setup wrong, I just think it doesn't pick up any better and I'm fairly disappointed because that antenna was $170, my other VHF antenna was $25 and does just as good of a job??? That makes no sense to me. As soon as I get that thing setup the way I want it I'll put the RTPRailfan stream back online. Till then....
