The All Copper X-Beam for 17 Meters - WA2UGT X-beam antenna for 17 meters band

2m VHF antennas with high gain - 2m SSB/CW-12.5 Ohm Yagis with extrem high gain and small bandwidth. These Yagis were constructed as ultra-light, portable Yagis with extrem high gain. They have small bandwidth and are working from 144,0-144,8MHz with good SWR.

A 40m Vertical - This antenna is intended as a simple, inexpensive solution for the newcomer to experiment across the 40m band (7.0–7.2MHz) when only restricted space is available

Mini-Beam Geometry Basics - There is a natural progression of the geometry of the "mini-beams" deriving from the basic yagi, which in itself owes a lot to the common dipole. By Dick Stevens, N1RCT

Why a Beam Antenna - Some basic antenna information for the newcomer

VHF / UHF Direct Connect Beams Lengths - Here are some lengths and spacings for various direct connect beams.

DK7ZB 144 mhz Yagis - High gain, good pattern and acceptable bandwidth. These aims can be realized with a radiation-resistance of 25-35Ohms, because the 28-Ohm-feedpoint is very simple to match.

Biquad Antenna Construction - This page details the construction of a biquad antenna. The biquad antenna is easy to build, and provides a reliable 11dBi gain, with a fairly wide beamwidth.

OptiBeam - optimum short-wave antennas, developed by hams for hams

NEC4WIN - NEC4WIN is a 32 bits commercial antenna simulation software based on MININEC3 developed by the Naval Ocean Systems Center in the 70s and 80s. It runs under Windows and can be used to simulate, analyze and optimize wire antennas, beams, verticals, etc. NEC4WIN has limitations. They are the same as Mininec3 on which the engine is based.
