Yes, but ... not everyone has a "high" antenna .. and many of those will
be closer to you than that "repeater 18 miles away" and yet, you *won't*
be able to talk with them. Because they won't hear you and/or you won't
hear them.

For current limiting in a point to point telephone system, figure 1000 ohms per
volt for the resistance to put in series with the phone handsets and the
battery. The current then will be about one milliamp.
