Many Types and Configurations of "Sloper" Antennas
http://groups.google.com/group/rec.r...7a96ab218b8103
NOTE : The "Sloper" Antenna normally needs a better
more consistent Earthen Ground under it than an
Elevated Horizontal "Flat" Wire Antenna.
* The "Sloper" Antenna is more of a 'Ground Reflective'
Aerial
* * The Elevated Horizontal "Flat" Wire Antenna is more
of a 'Free Space' Aerial. {Higher Up and Away from the
Earth 'Ground'}
.
The sloper's a vertical and needs a bottom half. Grounds work better 6
feet in the air than 6 inches below the earth. All antennas are dipoles.
