As some of the readers may know, an effort by members of the Canberra Linux Users Group has been launched to set up a Canberra-wide wireless LAN. This amateur experiment's existence is largely due to the acquisition of many cut-price old style Lucent WaveLAN cards being superseded by the IEEE 802.11 standard cards.
The cards were cheap but the tile antennas that came with them are no good for long haul links of more than several hundred metres. On top of this, commercial helical aerials antenna that can do the job are expensive, can get rather large and are ugly, especially the conifers. My Mum would not want one on her roof. Consequently, there is no reason why this aerial couldn't also be used with any other equipment that requires a broad bandwidth in the 2.425GHz band such as the new 802.11 wireless network cards or video transmitters. Wireless Booster.
If anyone does use the helical aerial with these bits of equipment, please let me know! The idea behind this aerial was for anyone to be able to make their own aerial for point to point links, and do it cheaply. The criteria are cost effectiveness, ease of construction and durability. Durability is important as you don't want wind, beak cleaning magpies and highly destructive nibbling cockatoos ruining your Quake III and Unreal Tournament sessions. Birds landing on the aerial have the effect of severely diminishing the signal, too. The aerial was derived from information on helical antennas in the ARRL Antenna book.
