 -> I just read a chart for VHF propagation. There's a dotted line labeled
 -> "Line of sight" at about 70-80 miles. It shows reception
of VHF at over
 -> a 200 mile limit however I suspect that would be mostly for FM radio.
 -> High UHF is mostly limited to "line of sight" unless there
is ducting.
 -> As for the flat land, the "line of sight" distance
increases a lot if
 -> the antenna site is elevated such as when erected on a mountain top.

 TW> Or places like Flat Land Amercia where they install 1000 Foot Tall
 TW> Antenna Towers.

Here in portland we've got the "West Hills". A basaltic ridge about
1000 to 1500 feet high. Gues where all the antennas are. And there's
one monster that must be close to that 1000 feet figure.
