wifi aerial

4 posts in this topic

i made a few of these http://www.hackszine.com/blog/archive/2007...5_bars_for.html

using copper wire that "fell" off the back of a telephone van

havent done any tests to confirm any signal/distance increases

also i left the insulation on the copper which is probably a mistake,

oh well i could always grab a blow torch and melt if off later

anything to help out those crappy 2dBi rubber duckies that come with everything

Don't worry about the insulation...it doesn't affect signal strength and will actually protect the wire from corrosion, etc.

edit:Ignore this since it only applies to lower frequencies...my bad

A handy hint for testing whether the insulation will attenuate the WiFi signal is to place it in a microwave (without the conductor!!!) along with a glass of water. If it gets warm, then it antennuates at around 2.4GHz which means it will effect your signal strength to some degree.

There are some antenna designs in this free book:
