I have a Thinkpad t60 which I use on the boat mainly. It has what I think is a socket for an external antenna- has a symbol a bit like an exclamation mark tapering towards a point at the top. Anyway, I have been using the wifi at the marina which is just about OK, but I was wondering if an external antenna would improve reception- I'm not sialing at the moment as I am in the middle of a big refit and being able to watch something mindless after a hard day's graft is a real bonus! Reception is not good enough for live TV over the internet but iplayer is OK. I have done a search and can't find much out there, at least in the UK. Any suggestions?
