Hi Bob

I was on my last morning pass and i was able to copy the S downlink quite 
steady from AOS  to about 15 deg near LOS as my roof top was 
blocking the signal. I know what you are speaking about i work a lot to find an 
antenna who will not have theses fades. I ended up with a 
WI-FI linear yagi antenna from Cushcraft model PC2415N.

I have their spec flyer i send it to you in another message.  I try a BBQ 
grill, Patch antenna, and a WI-MAX antenna before and they are 
all showing a lot of deep fades
