My prototypes don't look as good/neat as yours

transponder_top:
I dont have a voltage reg on this one. I don't have a one with a low enough drop out voltage. I will order some next time i order some stuff from digikey. These close up pictures show some ugly solder joints.

transponder_bottom:
I 3D printed an antenna holder/short circuit protector

Amp/Decoder:
I used BNC connector for amp to decoder connection. I already had some BNC jacks and cable(RG-59/U) around
