Next is an antenna. This is greatly influenced by whether you can get something outdoors (best) or put something in an attic (not quite so good, but useable - particularly if there's snow on the ground - soldering connections in 6 inches of snow is NOT recommended - been there, done that...) and how much space you have to work with.
Those little butane soldering irons are great for soldering outside in the winter time. I've used them a few times the past few winters. Picked it up at Home Depot, Lowe's may also carry them, too.
