I have a home LAN running a Siemens Speedstream model 2624 wireless router with print server. 2 SCSI computers attached by CAT5 to the router and the router attached to an ext home made BIQUAD antenna with a 5 metre RG58AU coax, has RP SMA to an 'N' type chassis connector housed in a weatherproof plastic container aimed at the side of my tin garage and a laptop with a modified Belkin PCMCIA card attached to a home made antenna connected to the laptop by a SMA PCB plug - SMA male connector and "N' type connector. The antenna is an empty modified 50 disk CDR plastic container with a CDR as the reflector, connected to an 'N' type connector with a copper wire having a small helical twist soldered in poking thru the lid. Both antenna together cost about $10.00 all up to make and less than 30 minutes labour. Needless to say I'm having a bit of fun running around my neighbourhood, laptop in one hand, antenna in the other whilst running netstumbler and seeing how well my various home built antennae are performing.
