Impact of External Resonance and Non-resonace Objects on the Radiation Pattern of RX Directional Antennas

Two new papers are uploaded in LZ1AQ site. Models are used to evaluate the impact of external conducting objects on the radiation pattern of directive RX antennas. They might help the users to understand sometimes unexpected behavior of their RX antennas.
