Thanks for that info. I'd heard good reports from users of the  
"Pringles" style antennas but this is the first I'd heard of the  
easier-to-make pseudo-parabolic reflectors.

Of course it depends on several factors, if the source of your  
interference is "on-axis" to your antennas they can actually make  
things worse.

Of course going with MPEG-4 is going to help a lot as well, since you  
don't have to push as many bits as with mpeg-2.

The one thing you didn't mention is the distance between your  
antennas, I'd be curious as to what range you are getting.
