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.

Build a hanging dipole for 2 metres - Described here is a simple omni-directional, vertically-polarized dipole for two meters. Made from coaxial cable, it can be rolled up and stored in a small container

Make your FM Dipole antenna - There is a simple, homemade antenna that can pull-in your favorite station.

Simple FM Dipole Antenna - FM Dipole for 88-108 MHz

K7MEM Center-Fed Half-Wave Dipole ( 3-30 MHz) - A Center-Fed Half-Wave Dipole is probably the simplest of antennas to construct and use. It is usually suspended between two supports, from it's end insulators, and has the feedline hanging from the center.

How to make a Simple Dipole Antenna - It is very easy to create a simple 1/2 wave dipole, all you need is some lengths of wire such as the core of some mains flex or even a straightened out metal coat hanger, some co-ax cable and a connector for your scanners antenna input
