Going through common antenna design compromises...
Depends on your location, of course, but the most effective thing I could do is get out of this valley. Next, I'd straighten the antenna wire and move the antenna outdoors (with a 75Ω coax line connecting it to the TV). You could also adjust the length so it's resonant at a particular frequency, but that will weaken the signal you receive on other channels. Alternatively, cutting it way longer than the minimum resonant length (like an order of magnitude or so) seems to make for a pretty forgiving frequency response. Then again, commercial broadcast transmitters are probably running enough output power that unobstructed line of sight makes more of a difference than anything else can.
