Hi Tom and List;
I don't know if you are looking for something to operate while in motion 
or just when you are set up but high sierra sells a package that 
includes a tripod that just sits on the ground and raises the antenna 
six or seven feet.  Don't know how much space you have so don't know how 
usable it would be in your situation.
I was kind of tempted only because in theory I should be able to set up 
in my yard and take it down when not being used.  The key word here, 
however, is theory.
