Build a space efficient trapped dipole antenna for 40-80-160 meter bands using RG-58 and PVC pipe. The document provides a brief guide on building a compact dipole antenna appropriate for the 40, 80, and 160-meter amateur radio bands. It explains the materials, building processes, and tuning methods required to provide best performance while preserving space. The paper also discusses theoretical elements of dipole antennas, such as impedance matching and feedline selection.

How to construct a very small but efficient Antenna with PVC Plumbing tube and discarded fruit cans. - Just the thing to fit in a small space such as the house attic

Build a portable VHF yagi antenna for 2 meters. All you need is two rabbit ear antennas from Radio Shack, two CATV baluns, four feet of 3/4 CPVC pipe with one tee.

Rigid Dipole antennas for 14 MHz band using PVC and Aluminium tubing

Drawings of shortened antenna for indoor usage, using short pvc tubes for 2 , 20 and 40 MHz by f1rfm

The 20 thru 10 meter dipole is constructed from stranded insulated wire available in most hardware stores. The feedpoint uses an 8 inch long section of 2 inch diameter PVC pipe. A section of wire joins the elements at either side of the feedpoint to avoid the inductance of square knots used on lower frequencies.

The 30 Meter Vertical Dipole is constructed from #10 stranded insulated wire available in most hardware stores. The feedpoint uses a T-section of PVC pipe. The coax loops through the PVC pipe to provide strain relief. by W1TR

This HALO design is not ground dependent and can be mounted atop a section of PVC.

A lightweight PVC hand-held telescopic 2 element 2m (145 MHz) yagi using two pairs of TV rabbit ear antennas as the driven and reflector elements. Approximate directional gain is 5dB.

This project explores the construction and performance of an Alford Loop antenna as an alternative to a round loop. The Alford Loop, symmetrically fed at opposite corners, behaves like a small loop despite its larger size. Built using PVC pipes and secured with tire wraps, the antenna integrates an LZ1AQ active amplifier for optimal performance. With deep nulls in its horizontal radiation pattern and improved resonance characteristics, this design has significantly outperformed previous active antennas in reception quality.

This project details the construction of a compact, circularly polarized Quadrifilar Helix Antenna (QHA) designed for 146 MHz operation. The antenna features a 1/2λ1/2λ helical design with a 2.6:1 aspect ratio, providing 4.5 dB gain and a spheroid radiation pattern. It is ground plane independent and compatible with both vertical and horizontal polarizations, making it ideal for terrestrial and space communications. The design includes step-by-step instructions for building the antenna using readily available materials like aluminum rods, PVC pipes, and RG-58 coaxial cable. The antenna's performance has been validated through comparisons with commercial omnidirectional antennas, showing superior results.

This Satellite Antenna Elevation System project involves mounting horizontally polarized Yagi antennas on a fiberglass reinforced polymer (FRP) crossboom. A Yaesu G-800DXA azimuth rotator is in place, requiring only an elevation rotation system. Elevation is controlled by a 12VDC linear actuator connected to a U-bolted arm on the crossboom, rotating within a DIY bearing arrangement. Common handyman tools suffice for assembly. The setup includes FRP crossboom, aluminum tubing, PVC couplers, nylon camshaft bushes, and a K3NG-based controller for azimuth and elevation control. Detailed guides and resources are available online.

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.
