“Buy a $10 radio and a $100 antenna” - Old ham radio saying.

The stock antenna supplied with the dongles is pretty hopeless. It is strongly recommended that a purpose built or purchased antenna is used and placed outside and as up high as possible. This is to get as much signal as possible and also get the antenna away from bad sources of interference - a laptop, PC and plasma and LCD screens will definitely create a lot of unwanted noise across the whole spectrum.
