ETS-Lindgren's Model 3301C Active Monopole Antenna is designed to provide reception of an electric field throughout its frequency range, in a single band, without tuning or band switching. ​The 3301C Active Monopole Antenna factor 3 dB roll-off points are at 170 Hz and 30 MHz. Between 250 Hz and 20 MHz, the antenna factor is flat within +/- 1 dB. To prevent saturation by the low-frequency signals, the lower 3 dB point is switch-selectable at 170 Hz, 1.9 kHz or 22 kHz. The 3301C is able to sense fields of +7 dB (uV/m) at 1 MHz with a 1 kHz bandwidth. Saturation will not occur below a field strength of 0.8 V/m, resulting in an extremely wide dynamic range to 141 dB. The saturation indicator alerts you of the need to use the internal attenuators.

The model 3301C antenna consists of a stainless steel rod, a counterpoise 61 cm x 61 cm (24 in x 24 in), a broadband high input impedance amplifier built into the base, and an AC power adapter for battery charging (nominal 90 to 265 VAC, 50/60 Hz). The front panel contains controls and indicators include a power switch and power-on indicator, a receptacle, and an indicator for the battery charger, a grounded female BNC output connector, and a signal saturation indicator. Power is supplied by internal AA size rechargeable nickel-metal hydride batteries.

Features:

  • 30 Hz to 50 MHz Frequency Range
  • Two Year Warranty
  • Individually Calibrated
  • MIL-STD 461G Compliant
