ETS-Lindgren's Model 3142E-PB BiConiLog is a hybrid antenna that combines innovative design, compact size, and excellent performance with an updated pre-amplifier module. This antenna enables users to measure a frequency range of 30 MHz to 6 GHz in one sweep, negating the need for multiple antennas and time consuming equipment setup. The antenna and pre-amplifier module are calibrated together including the cable section that connects the module to the antenna port. Any possible mismatch between the pre-amplifier and the antenna is taken into account in the antenna factor. Please note, the 3142E-PB is not intended for RSE testing of intentional radiators.

Key Product Information

​Frequency Range

The model 3142E-PB covers the entire range of the 3142E antenna from 30 MHz to 6 GHz.

Pre-amplifier Module

The pre-amplifier attached to the antenna has a frequency range of 30 MHz to 6 GHz and a minimum typical gain of 30 dB. The gain flatness is ± 2.5 dB and the noise figure is 3 dB above 200 MHz and 5 dB typical below 200 MHz. The power output is +20 dBm minimum at the 1 dB point. The input and output characteristics of the pre-amplifier are an input and output VSWR of 2​​​:1 maximum. The operating temperature ranges from -20°C to +75°C (-4°F to +167°F).

Emissions Antenna

The 3142E-PB is an emissions only antenna, with the pre-amplifier increasing the signal level received by the antenna. By placing the amplifier​​ close to the antenna, the signal to noise ratio is preserved in the amplified signal.

Flexible Mounting

The model 3142E-PB’s mounting bracket accepts either a 1/4 in x 20 thread screw or rear stinger mount. The pre-amplifier module attaches to the antenna via a flexible coaxial cable, so that the antenna can be supported by the stinger. The 3142E-PB includes two brackets to mount the pre-amplifier module to the carrier of any motorized mast. This allows the antenna to be scanned from 1 m to 4 .
