- The conventional configuration was an inverted-L arrangement with the vertical section going up about 13m and then a horizontal top-load wire extending about 8m, the end of which was supported by a tree at about 10m.
An automatically tuned 7-30MHz mobile antenna
- This is a base-loaded vertical antenna that mounts on the car's roof. The loading coil is designed as a variable inductor, with a three-legged chariot that travels up and down inside the coil, with grooved brass wheels running on the coil turns, and driven by a slotted rotor tube.
