Thanks for the info guys you have been really helpful. I wanted to get it all set up ready for the downpour tomorrow!!
Having plotted and planned I think I have it in a fairly sensible location and am now in the process of installing the software, from what I have read on various forums the Cumulus software is better than the one that you get with the kit so I have downloaded that and it seems to be working very well. It is asking for my location - longitude and latitude and asl any ideas where I can find that information?
