Club members will get together Saturday morning for breakfast and a discussion and planning session for a NVIS antenna build.
An NVIS (Near Vertical Incident Skywave) antenna is a type of radio antenna designed to transmit signals by reflecting them off the ionosphere back to Earth at relatively short distances, typically up to around 650 km (400 miles). This makes it ideal for local communications over a wide area, such as in emergency services, military operations, and amateur radio.
NVIS antennas are typically used on the lower frequency bands (like 160m, 80m, and 40m) because these frequencies are more likely to be reflected by the ionosphere. The key to their effectiveness is their ability to direct the radio waves almost vertically, which helps in covering a large area with relatively low power.
