John A and I had a short antenna email earlier today, mostly about the fact 
that both of the GPS antennas we were using died.

I asked a question about certain "commercial" antennas which included the 
Timing 2000, HP 58532A and the Datum 2640NW/DE, as to wether there were any 
opinions as to which is the better timing antenna. Neither of us has much 
of an idea, do you have any thoughts?
