These are all nominally circular orbit, high-inclination birds with a Mean
Motion just over 14 so you can expect 4-5 passes a day.  Most of these will be
low-elevation passes.  I'd recommend you try building a simple, omni- antenna
such as the TR with or without a groundplane

Or even a Lindenblad or a pair of Lindenblad antennas
