Re: BIG ISS and Shuttle reflection



Bob,

It was the shuttle. It crossed the fence at about a 45 degree angle. The 
sidelobes on the antenna must be strong enough to still make it show on the 
waterfall display. I am pretty much below the fence. I looked at it today 
again and it is still very strong.

Pieter
