Active antennas have become very popular for amateur radio LF and MF reception. A typical antenna (such as a diplole or vertical) are much too large for the typical suburban lot. Active antennas typically include the antenna itself, followed by a preamp or impedance matching circuit. Some active antennas are magnetic loops, while other designs are commonly called “E-field probes”.
Zwracam uwage ze ten typ amteny nie dziala jak dipol. Bardzo waznym jest wysokiej jakosci kabel miedzy antena oraz odbionnikiem, tak aby nie dzialal jak antena.
