Looking to mount a bigass antenna on the roof. 90% interested in FM, 10% in HDTV reception. I have a coax distribution amp already. I'm trying to pick up a low-powered college station (WKNC) about 18 miles from my house. My Jeep can pick it up just fine in my driveway, but my tuners struggle with indoor wire antennas. There are also a couple of great stations out of greensboro I'd like to listen to... and would love to get something out of Charlotte on a good night. Thoughts? Charles.
