Reference antenna options for 309 MHz to 80 MHz

There are two antenna presently used as the reference for radiated emission requirements. These are the halfwave tuned dipole, as required by the FCC, and the short dipole (resonant at 80 MHz) as required by CISPR. In a previous paper, (C.E. Brench, 1990) the difficulty of correlating these antennas to each other and to other commonly used antennas for vertically polarized emissions was examined. Some attractive options to these antennas for the 30 MHz to 80 MHz range are examined.<
