[amsat-bb] Antenna advice

[Jeff Mock <jeff@xxxxxxxx>]

I'm new to satellite stuff.  I got an Arrow-II antenna to get started. 
It works pretty well.  I live in San Francisco and I can go on the deck 
or hang out the window and hear the easy satellites.

I would like to graduate to sitting in a chair, inside, with two free 
hands, while working a satellite.  What is a good choice for the next 
step up for an antenna that I can install on a flat roof for mode-J 
operation?

Do I need an az-el rotator for the next step up or is there some 
cheaper/simpler solution?  It will be about a 75-foot cable run from a 
roof antenna to my radio, will I need a mast-head type preamp for the 
receiver?

thanks,
jeff
