Radio waves and antennas … and all that – Peter G3XJE
This presentation covers a range of antenna-related information so there should be something for everyone:
What makes a radio wave? Some mysterious properties of radio waves which you might not have appreciated. How do you launch radio waves? Antennas. Radiation resistance. Radiation patterns. Antenna gain. Transmitting and receiving. Getting power into, and from, your antenna. Resonance, or lack thereof. Feeders. Feeder impedance. Matching – does VSWR really matter? Why can’t you make a monopole? Multi-element antennas. Phased antennas.
