Antenna: http://www.radioshack.com/product/index.jsp?productId=2062691 75 ohm Matching transformer (close enough): http://www.radioshack.com/product/index.jsp?productId=2062054 Then you need an F-to-BNC and BNC-to-SMA or something similar, unless you're plugging it into a TVRX (which has an F-connector). Coax is commonly either 50 ohm or 75 ohm. Cable TV uses 75 ohm. For this application, either will work fine.
