You mean send it further? If so you need to look up how to build an RF amplifier. This will increase your gain GREATLY. You'll need a basic knowledge of electronics. Physical experience - soldering a building circuots is also a big plus. I managed to build an RF amp in electronics class when I was in highschool. I fed a lead from the antenna of a cheap ipod fm transmitter into the input of my circuit and got a substantial gain boost. I was able to transmit in a rough mile radius. Ill see if I can find scans.of my schematic for you.
