You need a QFH (quadra filiar helical) antenna as the signals are circular radiated. Sing whips can barely do it. They take some effort but work well, had one working for 2 years. Used 2 meter ham receiver to test 137 MHz where sats are and heard one first pass. The antenna with a dedicated amp , they are made for that band, and remote power so that amp can be mounted as close to antenna as possible realy pulls in all satellites.
