I forgot to ask you if you're using a preamplifier. If not, your reception will be greatly improved if you insert a preamp between your antenna and TV receiver. The preamp I'm using ony cost about $14.00 and it works fine. A preamp is pretty well a must if you're trying to pick up weaker stations, regardless of the type of antenna you have. Also try placing your antenna outside (with preamp connected) to see if that improves things. I've fallen into the trap of buying all kinds of antennas and I found, for the most part, that none of them really worked any better than the others (and I just wasted a lot of money). I built my own crude 4 bay reflector antenna at one point and it it worked about as well as those commercial antennas.
Actually, the commercial antenna that worked the best for me and the one I settled on is the smallest antenna of the bunch. It works extremely well on both the UHF and VHF-high bands as it is tuned for those bands. It's a log periodic antenna and it is only 750 mm. long. It looks like a small yagi but has elements with tapering lengths. This is one antenna that you don't hear ANYTHING about in OTA forums. I've tried all kinds of corner reflector yagi and multi-bay reflector antennas and this log periodic antenna works by far the best, at least for me in my location in Kitchener.
