An amateur radio operator from Australia, VK4ION, recently posted on her website a story about reading W2IK’s Emergency NVIS antenna construction plans and with some adaptation building her own portable ENVIS antenna system for emergency communications. Her website, VK4ION Emergency N.V.I.S. antenna, shows in detail, with many pictures, her construction of this antenna along with NVIS theories on how low antennas are perfect for local (under 400 mile) emergency communications. A photo of her ENVIS antenna is shown below.
Her report included comments such as when it was used during their “field day” operation it was the “hit of the show”. On her website is also a link to W2IK’s 4 part website on building the original antenna including the adapter for 80 meter and MARS operation. This antenna is the only NVIS antenna posted in the NAVMC MARS websites.
