Ohio NVIS Day takes place 27th April 2024 from 10:00 AM to 4:00 PM Eastern.

The purpose of NVIS day is to construct and try various antenna ideas, all working as NVIS (Near Vertical Incident Skywave) antennas. These antennas are low to the ground and provide coverage generally within a 400 mile radius- extremely important for regional HF communications in an emergency.

Additional details can be viewed via PDF on the Ohio Section ARES website.
