Tenna Dipper Kit
- The "Tenna Dipper" is a low power antenna analyzer and ATU tuning aid. With this handy accessory, you can determine the 50 Ohm resonance frequency of antennas or you can adjust your antenna tuner for a 50 Ohm match without generating QRM
50MHz J-Pole Antennapop
- Need a general purpose antenna on the magic band? The J-Pole is an easy-to-build and inexpensive device that provides an omni-directional vertically polarised antenna without the need for a ground plane. In technical terms, it is an end fed vertical 1/2 wave which is fed via a 1/4 wave matching stub.
Cebik Moxon Rectangles
- The Moxon Rectangle is growing in popularity as a compact 2-element array that approaches a full-size 2-element in gain but with a far superior front-to-back ratio and a direct match for the standard 50-Ohm coaxial cable.
Antenna system in a shopping trolley wally
- Multiband portable antenna system edited by Andy Foad G0FTD, consisting of an old cb antenna with it's 27Mhzmatching coil, an antenna tuner, car battery and a transceiver
Cubical Quad Antenna Designupdatedpop
- By N6VNG, can be used to determine the element lengths and the gamma match values for different frequencies, includes link to excel files with formulas to dimension your quad antenna.
Broadband receiving antenna matching
- This article addresses the subject of obtaining the best signal transfer from an antenna to the
typical 50-ohm receiver input over a wide frequency range, with emphasis on medium-wave
(500 – 2000 kHz), encompassing the standard AM broadcast band and the 160-m amateur band.
W8ZR High-Power Antenna Tunerupdated
- 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).
6m Half wave vertical
- This antenna is very useful for receiving or scanning purposes, but you can use it for transmitting, too. It is 2,94m long and has a pi-configuration (Collins-Filter) for the matching.
- Match & display imped of antennas, can graphically visualize and compare two sets of measured impedances simultaneously.

- A smarter version of the Smith Chart program. It allows you to dynamically generate impedance point plots as you configure each design element of an impedance matching network. Has an extensive Help file with a Wizard that tells you what steps to take in designing a matching network for a given load impedance. Complete Windows installation kit by w9dmk
- This database is not a logging program. It is intended to collect information about the HAMs that you know. You just record the call sign and name of a HAM that you meet. Later you can use QRZ to look up the call sign to validate that it matches the name.
