Antenna monitor for low power TX

I am looking for some ideas for a low cost circuit to detect if an antenna
has been broken or removed
from a 10mW transmitter.

At that power level why worry about a broken antenna ? The components
should be able to handle the loss . It would probably take more electronics
than it was worth. One idea is to monitor the current in the final stage
and see if it changes with the loss of the antenna.
