Parameters of active receiving antennas
Abstract
Operational parameters of active antennas based on the parameters of active four pole networks and standard antennas are examined. Gain, internal noise and distortion are discussed. Active antennas contain amplified units that influence noise levels at the receiver output. A double gate representation of an active antenna is used to investigate system characteristics. A 20 - 200 MHz receiver station with an active vertical dipole HE 109 serves as an example for using the parameters.
