direction finder

The Antenna Elmer - Here you will find information about wire antennas as well as directional beams.

Building an own Stackmatch - 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.

The extended double zepp - This wire antenna exhibits extraordinarily high gain in a bi directional radiation pattern.

Omni-Directional antenna for 6-Meters - Experimental omni-directional antennas for 6-meters band

A magnetic loop antenna for HF  ^pop - Able to cover all frequencies between 3.5 and about 10 MHz, the loop described here is directional, does not require a radial system, and stands just 1.8 metres tall. Most parts needed can be purchased at a hardware shop. The antenna can be put together in an afternoon and requires only hand tools to assemble. It should cost less than sixty dollars to build. by Peter Parker VK3YE ex VK1PK
