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

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.

This article describes a simple, inexpensive, dipole antenna that will rival the performance of a ten-meter beam.

Simple DIY stealth apartment antenna for 20m and 40m. It is basically a ZigZag quarter wave dipole antenna

A simple quarter-wave length vertical for 40m band using a 12 m spiderpole

A simple 7 bands off-center dipole wire antenna designed to work on 80 meters band and that can cover also 40m 30m 20m 15m 12m 10m with acceptable SWR

A simple TRAP-dipole project for 20 and 40m bands includes EZNec simulations

This article describes a simple Inverted L antenna for the HF bands designed to work on 80m, 40m, 30m and 20m

A simple to build full length 20/40 dipole antenna to be used in inverted vee configuration

A very essential j-pole antenna for 144 MHz. To adjust the SWR you will have to play with the 40mm distance between the coax feed and the braid inner conductor connection

This DIY homebrew project provides a durable, weatherproof center connector for dipole antennas, ideal for HF setups like 40m wire dipoles or inverted-V designs. Made from PVC pipe and an SO-239 UHF connector, it ensures strong support and room for a current balun. With simple drilling and assembly, it offers a cost-effective alternative to commercial options. Perfect for amateur radio operators, this dipole antenna connector enhances performance while keeping costs low. A great solution for DIY antenna builders seeking reliability and longevity.

This project outlines a simple, cost-effective 40m band HF dipole antenna design, ideal for beginners. Constructed with insulated copper wire and a 1:1 balun, it offers a 50-ohm impedance, suitable for both 40m and 15m bands due to the harmonic relationship. Calculations account for a K factor, ensuring optimal length and performance. Antenna modeling with 4NEC2 confirms practical access to both bands, though real-world results may vary. Lightweight materials and straightforward assembly make it an accessible and versatile amateur radio solution.
