Mobile coverage, power availability and weather can change quickly on caravan routes. Treat communication planning together with route information, emergency contacts and backup power.
Do not depend on one system
Carry a phone, suitable radio, broadcast receiver and printed emergency contacts. Share the travel plan with a trusted person and verify equipment conditions before departure.
Test before the journey
Check antenna, cabling and equipment mounts for vibration and weather exposure. Know the safe limits of batteries and portable power, and test every connection before travel.
