Hi Gordon,
I have used a Lindenblad mounted on a pole just 2 meters high
along with an ARR Mast-mount preamp and this works darn well.
For receiving the ISS and linear mode B satellites, you don't
really need a preamp but it will make a difference receiving
the packet satellites on 145.825 MHz.
It is also a good TX antenna for mode J satellites.
The Lindenblad (from QST) is here:

The ARR Preamp is here:

Best of luck and 73,
