If interference is shut down 18 miles is possible
and would be intermittent enough to make one curious.
An old rule of thumb is that the horizon is 21 miles for ships with sails.
and for a 6' person 3 miles, thus two people might signal each other at 6 miles.
Cellular or PCS cell site towers are typically 50-200 feet high. so possible.
