An homebrew antenna tuner project

Cannot find the inductors you need for an antenna, a tuner or amplifier ? Build your own it is easy!

This homebrew legal-limit antenna tuner is based on the famous "Ultimate Transmatch" introduced by the late Lew McCoy, W1ICP. The Ultimate Transmatch was described in the "Beginner and Novice" section of the July 1970 QST (Page 24).

This multiband wire antenna it is an off centre fed dipole, with 10 feet of vertical radiator, needs no tuner on 40m, 20m and 10m and works fine on all bands above 40m with a tuner, and even below 40m on 60m, and 80m.

The "EZ-Tuner" is a homebrew automatic legal-limit antenna tuner that covers all amateur HF bands from 160-10 meters. Using a T-network design and controlled by a BASIC Stamp BS2sx microcontroller, the EZ-Tuner will match at least a 16:1 VSWR for either unbalanced or balanced transmission lines.

This is a C-L-C type tuner with a reflected power indicator. Tuning is done for minimum reflected power.

An homebrewed HF antenna tuner

A simple T-network that can match any unbalanced antenna system by AA5TB

Homebrew balanced-L antenna tuner. Covers 160-10m. Designed specifically for balanced feedlines.

A new homebrew arial with +- 2.30 m lengt for tuner use only ,6m to 80m made by hans dg7pe

RF Choke to prevent hf currents on the feedline. This Magnetic Longwire Balun (MLB) makes it possible to efficiently use a coaxial lead-in cable with all forms of longwires, T-forms or other types of wire antennas, without the need for an antenna tuner.

Build an HF antenna tuner by VK5AJL

An off centre fed dipole, with 10 feet of vertical radiator. It needs no tuner on 40m, 20m and 10m by M0UKD

A home made antenna tuner based on the W6JJZ basic concept that ,atches balanced loads without the use of lossy baluns, can provide band-pass filtering and harmonic attenuation.

The Speaky HF SSB transceiver and other homebrew projects Homebrew of radio equipment, antennas, tuner, etc.

This type of antenna is a popular antenna design as the performance is very good across the HF bands and requires little or no tuning. It’s a dipole fed off center with a 4:1 balun at the offset feed point. The antenna shown covers 80, 40, 20 and 10 meters. The formula can also be used to adjust the overall length to cover more or fewer bands and the resulting overall length. 160-10m, 80-10m or 40-10 meters depending on your available space. Other bands will require a tuner.

There are quite a few variants of the design accompanied with many opinions on the effectiveness of the antenna. This page features links to some similar projects and a homebrewed personalized version of this portable antenna tuner

Homebrew Portable T-Match ATU, VK1AD Portable T-Match Antenna Tuner (ATU) mounted in a plastic case, T-Match ATU Schematic – 3.5 to 52 MHz power rating 80 watts

This describes a homebrew End-Fed Half-Wave (EFHW) antenna for low power SOTA, Parks and Field Day events. Made with readily available materials, it offers a resonant antenna in 40/20/15/10m bands without requiring an antenna tuner. The 19.8m long radiator wire in an inverted V configuration achieves VSWR below 1.5:1 for voice. CW users might need to adjust the length. Details include materials list, fabrication of the end insulator, and the 49:1 impedance transformer construction with a circuit diagram.
