Yesterday I bought an extra large aerial for our WIFI router at home. This should help us get good network reception in the living room. I can recommend these, the one I got was from Maplin and cost 15 quid, which means they are probably available for a bit less elsewhere.
Anyhoo, it works well, but I'm a bit confused about one thing. The aerial comes with a magnetic base, so that you can easily stick it to your fridge or whatever.
Great for a quick and easy way of mounting I guess, but I'm not sure how sensible it is to put a device designed to send and receive radio signals right next to a big lump of metal. Very strange.
