    cisco yagis can go 25 miles, at least thats what cisco says (meaning I bet they go further); I'm not disputing the reliability of yagis, I'm saying that if it can be done cheaper, why spend the extra money?

    The problem doesn't sound too difficult, especially if you can see between the two locations. I would reccommend using orinoco usb cards - they can be had for about 35USD on ebay, but you might not want to mess with shipping, etc to the UK. A couple friends and I recently used them to make a 55 mile link without amps... we were using 9 foot satellite dished though. We also had success using a cheap SMC AP, modified by putting an N connector on it. Using an AP would let you plug it straight into a LAN, however, the orinoco cards can also be configured as APs, or used alone in peer to peer mode (we used them in AP mode for our link). I don't know how easily the usb ones could be used on a LAN, we didn't really mess around with that aspect too much. However, USB is nice to use because you can locate the adapter at the antenna and really cut down on RF loss in the coax. I think there is a relatively short (~20 foot/6m?) limit on USB cable length though. If you do get one of the USB orinocos, make sure it is a Lucent or Avaya branded unit, I have heard of problems with the Proxim branded units (the newer proxims use a single PCB w/ no antenna connector while the others actually have a PCMCIA card with a USB converter... the PCMCIA card had an antenna connector).

    There are a number of antenna choices that should all work. I would lean toward the 18" dish antenna, but mainly because I have experience with the bigger dishes and like them... a cantenna would probably be easier to make. There are also plans for simple yagi antennas using threaded rod, nuts, and washers. This should give a bit more gain than a cantenna alone.

    Hope this helps,

    Andy

    smack thats all pretty interesting.. sounds cheap enough. what sort of price are the antennas? the sat ones? could i use the same acess point to sync my carpc? or is is purely directional with a sat? there is a bsd server in the loft area i could link to the usb.
