Abstract :
The special requirements to be met by vehicle-mounted antennas for use in near vertical incidence skywave (NVIS) applications are examined and the performance of both whip and loop antennas assessed. From these results it is apparent that the loop is the preferable configuration and an optimised, loaded loop antenna is presented. The loading is necessary to control the current distribution around the loop and a procedure for determining the value of that capacitive loading, using an equivalent transmission line, is presented and evaluated
