tuning inductor

SWR: Maximum allowable VSWR - VSWR (voltage-standing-wave-ratio) represents the degree with which an antenna is "matched" to the system impedance. Most modern antennas do not require any tuning for optimum performance. VSWR is one of the easiest parameters to measure and VSWR meters are becoming very popular antenna installation tools

Transmission Lines - Articles on SWR measurements and feed lines tuning.

Antenna Transmatch Tips - Tips on tuning antennas using Antenna Tuning Units also called ATU. This article explains the functions and ills of tuners, along with some guide- lines for building an ATU.

Detuning Towers - The goal of detuning is not to avoid resonance, but rather to minimize re-radiation and/or current in the interfering structure.

Remote Loop Tuning - Lyle Koehler's article on remote use of LF loop antennas for receiving purposes.

Antenna Tuning - Tuning mobile and base antennas, measuring SWR.

M1IOS - Wonder Whip antenna and tuner Priority listing - M1IOS Wonder Whip antenna - The M1IOS Wonder Whip A 10 dollars QRP Portable Multiband Antenna for HF, VHF and UHF A variation on the Miracle Whip and Wander Wand. This antenna tuning unit will get your SWR really low on telescopic whips, mobile 3/8th antenna and long wires. A remarkable little tuner that really works!

How to build a tuned loop antenna  ^pop - How can you vastly improve your Medium Wave reception? its quite simple really, all you need is 120 foot of wire, a few lengths of timber and an old tuning capacitor with which you can build the answer to every DX'ers prayers, a tuned loop antenna.

Optimizing Inductors - While intended mainly for antenna loading coils, this article also applies to other resonant systems, such as amplifier tank circuits.

The KO6YD Screwdriver Antenna Memory - The Screwdriver Antenna Memory (SAM) product is designed to enhance the mobile antenna commonly called the "Screw Driver". It replaces your current control unit and provides an automated memory feature that eliminates the visual coil tuning method commonly used.

VLF-LF And the Loop Aerial - The article discusses the theory of loop aerials for receiving and how they reduce the level of local noise. A Loop Aerial is described suitable for use on the LF and VLF bands together with a circuit of an interface loop tuner and preamplifier. The discussion extends to the problems of amplifier noise and the advantages of tuning the loop.
