A 10 meters band Slim Jim antenna project, made with a 450 Ohm slotted ribbon cable and secured on a 8 m fishing pole, by Steve G0KYA

Bobtails are vertical arrays that look like the letter "E" turned 90° clockwise onto its tails. They have 3 quarter wave vertical elements and are one wavelength long. The Half Square is a shortened Bobtail- it has 2 quarter wave vertical elements and is a half wave long.

The WT0G crazy W dipole, a solution for 160 meter operations

Add two parasitic elements to the sleeve dipole of a Netgear Router

A Half wave antenna has a high impedance feed point. This can be matched using a 1/4 wave stub matching section and converts the 40m vertical into an L-shaped 20m J-Pole antenna. The 300 ohm feeder used for this purpose must be kept away from the ground.

Yagi-logper is a linux GPL program to model a Yagi or Log-periodic antennas with horizontal cylindrical dipoles.

A lightweight inverted vee antenna that can be supported by a 10 metre long fiberglass squid pole. The antenna is designed to cover 10, 15, 20, 40 and 80 m bands.

Basic information on the folded dipole antenna

Ideal antenna for QRP work, as it has more gain over dipole.

A schematic antenna for a 40-80 Morgain dipole antenna with diagram and pictures, article partially in german

High End isopole VHF & UHF antennas for Amateur, Commercial and Military applications.

A balun is a MUST for dipoles or similar antennas when they are feed with coaxial cables. Many hams connect the center conductor of the coaxial cable to one side of the dipole, and the shield to the other. Wrong!

A J-pole antenna plan made using a half inch copper tubing

This article describes a project of asymmetrical hatted vertical dipole, a portable antenna that can be used for field day operations, sota, campings or even for fixed installations. This is a freestanding 20-10m antenna that is really easy to build, easy to tune and relatively easy to carry.

This 4m Slim Jim Antenna is cheap and easy to build yet it greatly out performs the more usual dipole due to its low angle of radiation. An SWR of 1:1 is obtainable across the 4m ham radio FM band with a simple adjustment.

This is an 80 metre dipole that fits in a small spac

The document provides a comprehensive overview of baluns, which are devices used to connect balanced loads, like dipole antennas, to unbalanced inputs, such as coaxial cables. It covers various types of baluns, including voltage and current baluns, and their design, construction, and testing. The text discusses the importance of baluns in preventing RF currents on coax shields and their applications in Ham radio setups. It also includes practical advice on selecting and using baluns based on antenna impedance and power ratings, along with detailed performance evaluations and construction tips for different balun configurations.
