Active Wideband Directional Receiving Antenna

A combination of a small magnetic loop and small electrical dipole or ground plane (GP), both vertically placed in a single point is widely used as a simple direction finding antenna. How to build a wideband version with active small loop and active small dipole is presented in the following publication: http://www.lz1aq.signacor.com/docs/active-wideband-directional-antenna.php . Analysis and experimental evaluation are performed. AAA-1 amplifiers are used in the active antennas.
