Tell me more about this rf sink
The technical term is "dummy load", most antennas are around 50ohm "impedance" which in an incredibly roundabout way means the antenna is indistinguishable from a 50ohm resistor at whatever frequency it's tuned to....which means you can replace the antenna with a 50ohm resistor.
This all assumes you care about leaving the radio functional (radio amplifiers will burn up if they can't dissipate the energy they're creating) and in most cases it's probably fine to just cut the trace as close to the source chip as possible. That said, if the system is especially evil and well engineered it'll throw errors in some cases so better to leave everything functional but unable to hear or transmit.
