I looked at http://www.antennaweb.org and got some good information about my OTA HD options. I am 15 miles away from most of the antennas, with line of sight (they're all in the same place), and up to 9, 14 and 32 miles away from three other antennas (all in different directions), with no major obstructions. antennaweb.org gives me this result: --- You need a Small Multidirectional Antenna. The smallest of TV antennas, these receive equally well from all directions. Designs include novel-shaped disks, patch antennas and antennas that attach to satellite systems. These antennas are most effective when signal strength is highest and away from reflecting structures or low areas. --- That's all well and good, but what make and model? Where can I buy them? Any thing in particular I need to think about with regards to the Series 3 TiVo?
