Put a note on the EPIRB. 'Antenna off, not able to transmit.'

You never know. I put notes on everything I take,stuff like ------ 'For Yacht in transit', value $200.00, I even put a copy of the boat papers, marina receipt and customs papers to bring the boat into the country along with a list of all the equipment and value in the bag.

Never had a problem. They have even opened up my bags but didn't open the boxes inside that had the boat stuff in it. Possibly because of all the paperwork.
