I wouldn't think the foil would attenuate the signal all that much. That said, you'll still enjoy better reception by placing an antenna outside the house. The size of the wire you choose is not that critical. Anything in the range of 18 to 22 gauge should be OK. What I've done for many years is to take at least a 30 foot length of copper wire with egg insulators on either end, mount it outside my house, and connect to the receiver using a shielded coax cable (rg-6 for TV is OK). What you do really just depends on how fancy you want to get. Having an adjustable attenuator on the radio should help to avoid overload. Just keep in mind that everything, including your target signal, is being attenuated at the same time.
