How about a receiver with variable attenuation? so you have a good signal
when all is well, then when you pull the antenna outa the tx'er, the signal
disappears from your receiver.

Hi,

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.

Initial thoughts are to measure SWR but I need a small, low cost circuit I
can place between PCB Antenna connector and the antenna.

Thanks in advance for any assistance

Kind Regards
