INSTALLATION
Location-The RADIOLA III should be placed as near as
possible to the incoming wire from the antenna. A good ground,
such
as a water pipe, should be not far away. The set may be

or elsewhere
out of the way .
Antenna
Outdoor Type-In general, best results will be obtained with
an outdoor antenna from SO to 150 feet long and 20 or more feet
above
the ground. If these dimensions cannot be secured, ap-
proach
them as nearly as possible. The antenna should be located
in a space above
the tops of surrounding buildings and in a space as
free as possible from
other objects. It should not be touched by any
