Simple Ham Radio Antennas--80m END FED NVIS FIELD ANTENNA

If you're having trouble viewing this video, please insert this title link into your browser search box: This is post #969 in a continuing series of simple ham radio antennas. Near Vertical Incidence Skywave Antennas (NVIS) are ideal for local or regional contacts, especially during times of natural or human-caused disasters.  HF NVIS antennas form the emergency "backbone" to the VHF/UHF bands usually used for local emergencies.  If repeaters are lost or greater distance is required to contact emergency management officials, then simple, portable NVIS antennas can provide the necessary "gap filler."  A properly designed NVIS antenna can provide reliable communications up to 300 miles/480 km or more depending on propagation.

In this video, NG9D describes a basic, easily-made 80 meter NVIS antenna suitable for portable or emergency use.  NG9D provides installation details, theory of operation, and a brief demonstration of how the antenna is deployed and used.  You may want to make one of these NVIS antennas for your emergency "go kit."
