Let's bump this to the top...
Robert @ Tragic Little Aerospace has been incredibly helpful with helping me correct my mistakes! I've managed to sever the coaxial antenna cable on the transmitter while cutting electrical tape with a utility knife and damaged the receiver cable by pinching it in my car door. On both occasions, Robert directed me to the correct Digikey products so that I could order (multiple) replacements. I now have 5 coax cables and 2 receiver cables/antenna bases. Needless to say, I am good to go.
If you're reading this, thanks Robert! If you're contemplating getting a stand alone GPS tracking system that doesn't require a Ham license, look no further!
