Was the USB device designed to feed a 50 or 75 ohm load?
If it is then great...get a cheap dipole FM receive antenna and hook it up.
If it was not then attaching something to the transmitter stage will load it differently.
The output stage was designed to resonate with the L and C and equivalent R of the board it was built on. Nothing more nothing less.
RF transmitter stages are not like an audio amp.
RF load impedance can be affected significantly by loading and can either lose significant signal or load the output device to the point of destruction.
Not recommended but play anyway...hope the thing was not expensive.
