Periscope Antenna
In
telecommunication
, a
periscope antenna
is an
antenna
configuration
in which the transmitting antenna is oriented to produce a vertical
radiation pattern
, and a flat or off-axis parabolic
reflector
, mounted above the transmitting antenna, is used to direct the
beam
in a horizontal
path
toward the receiving antenna.
Note:
A periscope antenna facilitates increased terrain clearance without long
transmission
lines, while permitting the active equipment to be located at or near ground level for ease of
maintenance
