Here's your MOHU FAQ -

▶ I heard that the Leaf doesn’t receive VHF or Hi-V band stations. Is this true?
This is false. The Leaf® does receive VHF or Hi-V stations. The Leaf® is optimized for UHF stations, which comprises about 95% of the TV stations today. The Leaf® will still receive VHF stations but it will not be able to receive them from as far away as the UHF band stations.
So it's false but no different from any other small antenna. The Leaf is optimized for UHF frequencies, which have a much shorter wavelength than VHF. It's not deaf to VHF, but the VHF station has to be comparatively stronger than a UHF station to be received. How much stronger they are not saying - I'd guess a
lot stronger.
Indoor reception operates at a significant handicap compares to an outside installation. One test you could do is take your Leaf up on the roof and see if it receives 10 from there. You'll get a significant boost in signal power by going outside the shell of your house and higher.
Take a look at this thread -
http://forum.tvfool.com/showthread.php?t=15160 - mostly addresses the same issue that you are facing. In your case, ch 10 will be easier to receive with a moderate sized antenna than ch 3 talked about in the thread. You'd probably get all your stations, 10 and more with a modest antenna like the RCA ANT751
