Being a recent newbie to the LEOs it had never even occurred to me that too
narrow a beam width could present a problem with staying pointed at those
satellites. Thanks, Reid, for bringing that thought up in my mind. I wasn't
taking it out of context. I was just wondering if it was an unforeseen
problem (by me) that I needed to address. It's things like this that allow
us to learn.

It appears that a narrow beam width is not normally a problem and I thank
John and others who pointed that out.
