I have an HDHR and a Haupauge and am in a fringe signal area.I can confirm  
that bad weather can cause these symptoms.I improved things by removing  
some trees and fine tuning the aerial direction.I used my TVs signal  
strength display to do this.I have an inline signal strength meter but the  
TV is more precise.I tuned for best gain and best quality.It is possible  
to have high signal gain and crap signal quality.
