At the heart of the transmission of every radio signal is the antenna, and the simplest construct is the dipole. So basic is the dipole antenna that the half-wave version is in nearly all ...

Antennas are an essential part of radio telecommunications equipment, bridging the gap between electronic and electromagnetic signals. The shape and size of an antenna is a strong clue as to its type, ...

When you think of directional ham radio antennas, you probably think of a Yagi, cubical quad, or a log-periodic antenna. These antennas usually are in a horizontal configuration up on a high tower.

Much of the work of Spectrum Planning Group is based on well-established principles of 'antennas and propagation'. Propagation matters have received a lot of attention over the years and much has been ...
