Hi all,
I posted here a little over a year ago and got some great advice, all of which I took, where I could. (eliminated wiring, splitters, amplifier, as issues) So, here is where i'm at:  I have an Antenna’s Direct DB4e, a C2V reflector and an amplifier. My tuner is a TiVo Premiere.  My antenna is outside, above the roofline, oriented in the right direction.  Here is my TVFool info:

I still occasionally get break ups, particularly on Fox 29.  Based on all of your help, i have concluded that my problem is a wall of mature (60ft tall) trees, about 50 ft away.  There is no way i can get the antenna any higher and the trees aren't going anywhere. 
So, do I have any options remaining?  Could I upgrade my antenna? If so, what what antenna would you recommend that is better than what i have?  Any other suggestions?
