The W5GI Mystery Antenna is a multi-band wire antenna that covers 80 to 6 meters with low feed point impedance. It is easy and inexpensive to build, similar to a G5RV but performs better on 20 meters. The antenna is difficult to model but has received positive feedback from users worldwide. It is ideal for hams without towers, requiring only two vertical supports about 130 feet apart. The antenna consists of three half waves in-phase on 20 meters with a half-wave 20 meter line transformer, offering a six-lobe pattern, gain broadside to the antenna, and low feed point impedance for easy matching.
