Hex Array - 80/40 Meter Vertical - This page describes a homebrew 80/40 meter trap vertical antenna. Includes an interesting antenna raising system that allow easy setup and tuning.

Bruce arrays for 80 and 160m - Antennas with gain and bandwidth for 80 and 160 meters band. Simple wire antenna capable of considerable gain

Directional arrays - About collinear array antennas

The 7-Hex Driven Vertical Array - The array consists of 7 vertical antennas arranged as 6 verticals in a hexagon shape plus 1 additional vertical in the center of the hexagon

Definition of Collinear antenna array - Wikipedia page about collinear antenna arrays

Baluns on Log Perodic Antennas - Some antenna manufacturers place baluns at the incorrect location in LPDA arrays. If we consider what the balun does we can see how the mistake occurs.

Half wave collinear copper jpole - Two meters collinear j-pole antennas made with riggid copper pipe

5/8 Collinear antenna  ^pop - A 5/8 wave stacked j-pole antenna plan

Design your Own Super J Pole - Javascript for calculating the lengths of tubing to be used for the construction of a Super J-Pole in a collinear design

The Simple Collinear - Wherever there is a need for a vertically polarized omni-directional antenna with gain, a collinear is used. The vertically polarized collinear takes the form of two or more half waves in-line and in-phase, resulting in an omni-directional pattern with maximum radiation near the horizon.

Omni-Gain Vertical Collinear Antenna - This rugged antenna, an omnidirectional collinear, is capable of surviving harsh environments. It's a good choice for repeater installations and can be top, or side mounted to the tower by WA6SVT

802.11 2.4Ghz Low-Power Vertical Antenna - A 2.4Ghz low-power 5dBi vertical collinear antenna for 802.11 applications

Home-brew Compact 6dBi Collinear Antenna  ^pop - This page details the construction of an easy-to-make collinear 360 degrees omni-directional, vertically polarised, antenna for 802.11b/g wireless networking.

Collinear Microstrip Patch Antenna - Design of a 869 Mhz Collinear antenna

An improved 40-80 double extended zepp - Article originally published in ARRL compendium by N6LF revisits the classic double extended Zepp to improve pattern and SWR bandwidth. The DEZepp is essentially two end-fed collinear dipoles.

Optimizing half-wave sloper arrays for 160 meters - This article presents a 160-meter variation of this family of antennas and, more importantly, a discussion of the details of how to get such a beast working really well.

Kings Electronics - Manufacture a wide array of RF interconnect products for operation from 0 to 18 GHz, ranging in size from subminiature connectors to large, high voltage types

A new method of radio direction finding Priority listing - A method of finding radio sources with antennas based on omni-directionality (the less directional the better coverage). Uses energy levels and some sophisticated math (encompassed in a free software download on the site) to find x,y,z coordinates of the fox relative to the center of your antenna array. Can be overlayed on a GPS map to help you locate in real-time.
