Model 3301C Active Monopole Antenna User Manual

2024-11-21
●The ETS-Lindgren Model 3301C Active Monopole Antenna is a broadband, high sensitivity electric-field receiving antenna. The Model 3301C is composed of:
■ Monopole element
■ Counterpoise
■ Broadband, high input impedance preamplifier
●The monopole and counterpoise function together as an electrically short antenna over ground plane. The preamplifier provides impedance transformation from the high impedance at the base of the monopole to the 50 ohms required by most receiving systems, and provides power gain to allow the sensing of low-level signals.
●The Model 3301C is designed to provide reception of an electric field in a signal band without tuning or band switching from 30 Hz to 50 MHz. The 3 dB roll off points for the antenna factor are at 170 Hz and 30 MHz. Between 250 Hz and 20 MHz, the antenna factor is flat within +/- 1 dB. Despite the roll of the antenna factor, the usable range is 30 Hz to 50 MHz.
