you could makean home made cantenna !! i watched this program ages ago and the idea for a cantenna came from africa , there are alot of hills and they we`r tryn to figure out a way to get the signal from hosipital to hospital ,, any way the signal go in a circular motion so they got an old tin of large bake beans put an hole in the bottom and poked the antenna through it ,, then aimed it in the direction of the other one and hey presto (probably with a bit more modification i think ) they made a connection ,,
Hence the name CAN-TENNA i was toying with the idea of doing this with my wifi as its not good and only nxt bedroom !! i thought a small tit of sweetcorn would be about the right size lol
not tried it yet but be my guest anyone and let me know how you get on lol
