As Tower Guy said, you need some real gain in order to overcome the losses from being in the attic. Doing the math... The predicted Noise Margin for WLOS is 22 dB. Take 20 dB out for losses through the roof and other stuff and yo are very close to no lock. Add a little cable loss and you're right at threshold.

As far as size goes, you can't fight physics.
