1.0 Introduction
The ETS-Lindgren Model 3303 Rod Antenna is a passive broadband
electric field monopole transmitting antenna, and may also be used as a
passive receive antenna. The Model 3303 has a frequency range of
1 kHz to 30 MHz and features manual band switching between
0.001-5 MHz and 5-30 MHz. The maximum power handled by the
Model 3303 is 1 kW.
The base of the Model 3303 is constructed of aluminum, providing
strength and portability. The 1/4–20 threaded receptacle in the base is
compatible with ETS-Lindgren tripods and most others. The housing
contains the band-switching mechanism and a female Type N connector.
Each Model 3303 is individually calibrated
per (ESCM) or IEEE Std 291 using NIST
traceable equipment. Actual individual
calibration factors and a signed Certificate of
Calibration Conformance are included with
each antenna. By knowing the actual
antenna factors and performance
characteristics instead of typical data, you
can more accurately calculate the
field strength in your tests.
