Multiband HF Projects - Beam Antennas

Why A Beam Antenna? by W1ICP
Some basic antenna information for the newcomer about Yagi antennas including a tutorial on antenna gain and construction of a 15-meter beam antenna.

Simple Gain Antennas for the Beginner by W1FB
You need not be a structural engineer or invest an absurd amount of money to build a beam type of antenna. Good performance can be obtained with simple antennas made from some very ordinairy materials.

5-band Broadband Hexbeam by OM2JU
Hexbeam is in fact modified 2-element Yagi antenna designed with goal to maximally save the space. The driver element has W shape, the reflector is mirror image of the driver.

A Portable 2-Element Triband Yagi by VE7CA
Have you ever dreamed about a portable beam you could use at your summer cottage, while camping or on Field Day? Dream no longer. This portable beam can be rolled up and stashed in your car’s ski boot!

Delta Matching HF beams (now with tables for all bands) by PA3HBB
In most of the book on antennas there is a section covering making VHF or UHF beams using a Delta match to feed the driven element. In this article, I explore the use of such an easy matching system on H.F. antennas.

Horizontal HF 6-Band turning arranging emitter with 2 elements "Maria Maluca" by DL7JV
Since 2004 I have a small garden in Berlin. After the house was built and worked some small contests with the existing portably wire antennas, 2007 the desire for swivelling multiband HF antenna arose.

KD6WD Moxon Antenna Project by K6SGH
Basically, a moxon rectangle is a 50 ohm two element wire beam antenna. It consists of a driven element and a reflector. We use some simple software designed by Dan Maguire, AC6LA, which was first published on L.B. Cebik's website, to identify all the critical measurements.

My Delta Loop for 10/12/15/17/20 mt by IK4DCS
MODIFICATIONS FOR A DELTA LOOP ANTENNA. This is not a theoretical text but the result of many experiences lived through the action of two heavy wind-storms.

Practical High Performance HF Log Periodic Antennas by K8CU
How do you go about achieving good DX performance on all HF amateur bands from 10 to 30 MHz without using separate antennas for each band? One alternative that occurred to me was the log periodic (LP) antenna.

The Queen of Antennas: The Quad by IZ7ATH
The choice of a beam instead of an other depends on many factors: electric properties (Gain, F/B ecc.), weight, encumbrance, resistence to the wind, appearance ecc.; in a word: IT'S AN ARRANGEMENT!
