Mark,

I love my little Diamond A-502HB two element HB9CV. Everything goes
together with wing nuts and it uses captive clamps and such so that you
don't have to keep track of a bag of hardware. Seems to be pretty much
laser focused for portable/rover ops.

If you want a couple more dB, Comet has a version with two directors in
front for a few more bucks. CA-52HB4 is the model I believe.
