NVIS (near vertical incident skywave) antennas are perfect for local, state, and regional communications during portable or emergency operations. NVIS antennas radiate signals at a high angle, making them ideal for coverage out to approximately 300 miles/486 kilometers. I've used low-slung dipoles (approximately 17-feet/5.182 meters above ground) for local Hawaii nets and rag chews around the state.
In this video from "Commsprepper", we learn how to set up a basic NVIS antenna based on a design from W9WIS (http://w9wis.us/NVIS.html). This antenna is simple, easy to erect, and inexpensive. Other NVIS antennas can be configured as tuned end-fed wires, low level loops, and even magnetic loops. Have some fun and build a NVIS antenna today.
