For mounting antennas in a tree, I suggest you look at the new TriplePlay antenna. It is compact and built from solid fiberglass. This will survive blows from falling ice and limbs up to 2 inches in diameter. With a 7777 pre-amp and a clear view to the stations It could do all of the channels on your needs list, with the exception of channel 12. Use with the any of the above suggested configurations for best results. See the antenna at
