I'm afraid that you've got two things working against you for an attic installation:
1) All of your signals are in the "pink" range. This means they're so weak that a rooftop installation is really the best way to go.
2) You have a low VHF channel to contend with (WTVF, ch 5). VHF stations, especially low VHF ones, require antennas with very long receiving elements. You'll need a fairly large antenna to have any real sensitivity on these channels.
Sorry, but there aren't any "magic" antennas that can overcome the laws of physics. There's plenty of marketing hype that would have you believe that such an antenna exists, but in the end, a larger outdoor antenna is the best solution for your situation.
A combo antenna like the Winegard HD7080P might work for you, but it's 7 1/2 feet long and 9 feet wide. Just about any full band (VHF and UHF) combo antenna with respectable gain will be at least this big, if not bigger.
It's also interesting to note that all the VHF stations are north of you (compass heading of around 12 degrees) and all your UHF stations (with the exception of channel 27) are south of you (compass heading of around 167 degrees).
You might get better results by combining two antennas. One UHF antenna pointed south, and one VHF antenna pointed north. They could be combined very efficiently through a UVSJ combiner or a pre-amp with dual inputs (UHF/VHF).
An good 2-antenna setup for your situation would be something like a Channel Master 4221HD (UHF) pointed south, a Winegard HD5030 (VHF) pointed north, and a Channel Master 7777 pre-amp (has an option for separate UHF/VHF antenna inputs).
I don't know if you can fit a 10 foot long antenna like the HD5030 in your attic and have it pointing north.
A do appreciate your desire to keep the antenna in the attic, but please do reconsider an outdoor setup. A chimney mount or eave mount might not be as bad as you think, and it's certainly a lot easier to work with antennas of this size when you're out in the open.
