The SS2000 is absolute JUNK. At that distance, you should attic mount a Channel Master 3016, and point it toward Wichita. It's available from solidsignal.com for $29.
Use the balun kit included with the antenna and run some RG-6 to the HDTV. You can get some good RG-6 cable from RadioShack, Lowe's, or Home Depot. You might need only a 25-foot run, maybe longer (up to 50 feet).
