The EMCO 3303 is a passive broadband electric field monopole antenna designed for both transmitting and receiving applications. It operates within a frequency range of 1 kHz to 30 MHz. The antenna features a switchable matching transformer with two positions, designed to present impedance to the drive amplifier while powering a high impedance rod. The transmitting rod is constructed from stainless steel and is adjustable, with a range from 20 inches (50.8 cm) to 41 inches (104 cm). In typical usage, the rod is extended to its full 41-inch length. The base of the unit is an aluminum housing that contains the band-switching mechanism and a female Type N connector. This antenna is suitable for EMC testing and is individually calibrated according to the equivalent capacitive substitution method (ECSM) and IEEE-291 methods, utilizing NIST traceable equipment.
