ETS-Lindgren 3303 Passive Broadband Monopole Antenna 1 kHz - 30 MHz

The Model 3303 is a passive broadband electric field monopole transmitting antenna that has a frequency range of 1 kHz to 30 MHz.

It features manual band switching between 0.001 - 5 MHz and 5 - 30 MHz. The maximum power handled Model 3303 is 1 kW. The transmitting rod is stainless steel and is adjustable from 50.8 cm (20 in) to 104 cm (41 in). In normal test use, it is extended to 104 cm (41 in). The base is an aluminum housing which contains the band switching mechanism and a female Type N connector. The Model 3303 also may be used as a passive receiving antenna.

All ETS-Lindgren's rod antennas are designed to provide a high level of efficiency in electric field measurements. Every rod antenna is individually calibrated in accordance with the equivalent capacitive substitution method (ECSM) and IEEE-291 methods using NIST traceable equipment. By knowing the actual antenna factors and performance characteristics of an antenna instead of typical data, you can more accurately calculate the field strength in your tests. Annual recalibration is recommended on rod antennas.
