i have the same one, but i got it for 20+10 shipping. it only has 500 feet or range, and i made it a lot longer by attaching a really long tv cable where the antenna goes, putting a connector on the end of it, and attaching the antenna to it. it doubled the range, so if you mod the antenna, it could get up to four times the range. or you could find a huge tree, and tie the tv cable to it. just some ideas.
