    Just How to DIY an NVIS Antenna AKA Cloud Burner Antenna Utilizing a Mag Mount

    Part of being a ham radio driver is to give communications in times of emergency situations. With the upcoming Ohio NVIS Antenna Day, I chose to look into NVIS antennas. NVIS antennas, additionally referred to as Near Event Vertical Skywave antennas have a high angle of radiation. Something on the order of 60 degrees, to directly to 90 degrees. Unlike UHF and VHF signals, which normally have a 50-mile range with a yagi antenna up high, and also NVIS antenna is made for interaction in the 75-- 500-mile variety. Occasionally an NVIS antenna is referred to as a "cloud heater" since it routes a lot of its radiation extra upward than a regular antenna.
