How to build your own beverage antenna for 80-160 meters band by K5ZD

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!

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.

Homebrew a cobwebb antenna for the HF bands. This page describe a cobwebb multiband antenna resonating on 14 18 21 24 and 28 MHz. The cobweb antenna model can be considered a fan dipole, or better, multiple dipoles fed in parallel.

Every ham needs an RF power meter. Here is a high performance unit to build at home.

Nowdays lots of people are putting up antennas to either beam in different directions at the same time or just to stack them and get a lower angle of radiation. Use this stackmatch to match you array.

Backpacking, boating or mountaintopping ? Invest your time and pack this novel directional gain antenna on your next expedition

Building a cavity resonator for 144 MHz

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.

Building an omnidirectionnal antenna for the 23 cm band, 1240 - 1270 Mhz

Paddles made from readily available materials, like double sided PC board material and cost almost nothing to build.
