I agree with Neil that you should start with the 3M wire antenna supplied with the kit. You can try hanging it out the window or run it up along the wall in your apartment to see what works better for you. I had an interesting experience with mine. I draped the antenna over my TV set in the living room and it covered my entire block, a distance of about 500-600 feet, with an extremely strong signal. I surmise that the antenna was radiating into the degaussing coil that sits around the picture tube, and was being coupled into the AC power line that way. Any time you move the position of the wire or change anything that is hooked up to the transmitter, please re-check the tuning.
What are your intentions as far as coverage is concerned? Are you trying to cover your own apartment, the entire building, or as far as you can get outside the building? This will determine what kind of antenna will be needed. You could potentially get a CB antenna (102″ steel whip), mount it on your air conditioner, and feed it with a loading coil like the one featured on the SSTRAN web site. You could also use just a plain piece of wire dropped out the window with an external loading coil. I have to say that tuning the loading coil might be a bit difficult for a beginner, especially without any test gear. If you rely on the tuning network that is built into the transmitter, tuning is very straightforward, but efficiency is lower.
Grounding is another important factor. It will likely be impossible to find a good RF ground in your apartment, but you can try the outlet cover screw or a cold water pipe if you have one handy. Keep in mind that if the pipe is not made of metal it will not do you any good.
