Chpt 4 - Propagation, Antennas & Feedlines

No piece of equipment has as great an effect on the performance of a radio station, whether hand-held or home-based, as the antenna.  Experimenting with antennas has been a favorite of hams from the very beginning, contributing greatly to the development of antennas for all radio services.  To choose and use an antenna effectively, it’s important to understand some basics of propagation – how radio waves get from one place to another.  For these reasons, knowledge of antennas and propagation is very important for amateurs. 


This page is organized to support the Fifth Edition of the Ham Radio License Manual.
