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 "-" Luc Leblanc VE2DWE Skype VE2DWE www.qsl.net/ve2dwe WAC BASIC CW PHONE SATELLITE _______________________________________________ Sent via [email protected].
