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 ( 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.
