Omnidirectional Antennae
It is possible to make a homebrew omnidirectional antenna, as shown in the guides listed on Links#Antennae.
Directional Antennae
Cantenna
The instructions shown the websites listed on Links#Antennae were used ti build some cantennae as shown in the pictures:
File:Circular waveguide optimise.xls
Sectoral Antenna
Turn an Omni into a Sector
The reflector designs shown, found at Freeantennas.com can be applied to a standard omni and will turn the omni into a sectoral antenna.
Simulation
NEC 2 was used to generate the simulated field pattern for a cantenna with the dimensions used in our first test cantenna.
