Antenna Briefs #2 - Power, Range, and Licensing
How far can radio / wireless signals transmit? In this second video in the series, we look at the relationship between power and range, and the antennas used. While the topic can be quite complex, the aim is to illustrate the core issues involved. Transmitter range values from 130 meters to millions of miles are possible once the concepts are understood. However, there are restrictions on antennas and power levels allowed, and transmitting in general requires a license. The key reasons for licensing are briefly discussed.
