Antennas

This page gathers HamWiki's articles on antennas and the feed lines, matching devices and accessories that go with them.

Start with

• Dipole antenna — the simple wire antenna most hams build first
• Vertical antenna — a single upright element that needs little room
• Yagi antenna — a directional beam of parallel elements on a boom
• End-fed half-wave antenna — a half-wave wire fed at one end instead of the middle
• Feed line — the cable between the radio and the antenna
• SWR — how well the antenna is matched to the radio and feed line
• Antenna tuner — a matching network that makes the load look like 50 ohms
• Balun — joins balanced and unbalanced lines, such as coax to a dipole
