G5RV 40m Beam Antenna. Adding a 28 ft. piece of vertical wire to one end of a 102 ft. center-fed dipole turns it into a 40m beam with a very wide beamwidth -
This project started as a result of renewed interest in 40 meters coupled with the desire for an antenna system that would be more effective than the simple dipole. -
A helically wound two element 40 meter yagi beam antenna from a 1974 QST article -
A 40 meter band two elements yagi beam with a 6mt boom with pictures and drawings -
A 3 element yagi beam for 40 meters band -
This article describes a simple, inexpensive, dipole antenna that will rival the performance of a ten-meter beam. -
An antenna project for a beam antenna for 7 Mhz -
This page describes a comparison study on seven different beam antennas for 40 meters band. Yagi antennas, moxon antennas, mini horse all antennas are described with schema diagram , azimuth plot and SWR F/B Gain diagram -
A review of the SteppIR UrbanBeam antenna a two element Yagi antenna working 40-6 meters. The UrbanBeam is a good choice for those thare are limited by lot size, regulations, city regulations. -
A dual band 40-80 vertical antenna on an 18m Spiderbeam Fiberglass Spiderpole, with monoband performance -
The author reflects on expanding their antenna for 80m coverage during lockdown. They extend the End Fed Half Wave (EFHW) using a Spiderbeam pole and "cheating" by dog-legging across their garden. Despite challenges, they achieve coverage for multiple bands with minimal cost. Practical Wireless features EFHW antennas, including a pre-made 20m EFHW extended for 40m. -
A custom center hub for a Spiderbeam yagi antenna, enabling side-mounting on an existing mast. Challenges included structural instability, limited reach for assembly, and interference with a pre-mounted Spiderpole. A new hub using 40x40mm aluminum tubing provided strength, allowed side assembly, and supported fiberglass pole guy lines. The solution facilitated efficient installation and removal, delivering excellent performance compared to a SteppIR yagi.
