In general a 12 metres antenna installation is preferred and can be made using an 8
metres whip and 4.5 metres feeder or a 10 metres whip and 2.5 metres feeder. In both
cases the whip should be mounted on a pole providing sufcient height to have the
Antenna Tuning Unit mounted such that it allows for the feeder to be erected at an
angle of 45 to 60 degrees, creating a combined 12 metres vertical antenna system.
The feeder wire is terminated at the antenna horn at the top of the Antenna Tuning
Unit. Use a supporting insulator near the ATU to carry mechanical stress from the
feeder wire. Use a short exible part of the feeder wire between the supporting
insulator and the ATU horn in order not to ap-
ply mechanical stress to the antenna horn.
To maximize the radiated power and avoid ash
over, keep distance to metal parts as long as
possible, preferable more than 100 mm. Use a
short direct ground connection from the ground
clamp at the bottom end at the Antenna Tuning
Unit to nearest suitable metal ground plane.
It is recommended to use the ATU mounting
bracket for the physical tting of the ATU.

A passive type antenna of 6-10m electrical length is recommended as receiver an-
tenna. The antenna should be erected well in the clear and kept away as far as possible
from electrical equipment to minimize noise interference.
It is recommended to provide the installation with an impedance matching transfor-
mer inserted at the antenna. The matching transformer grounding cable should be as
short as possible and connected to ground through welded bolt. The antenna feed-in
shall be by coaxial cable.
In case a passive antenna for practical reasons cannot be installed, it may be repla-
ced by an active type antenna. It is however, important to emphasize that an active
antenna may decrease the receiving capabilities through reduction in received signal
level and receiver dynamic range. The installation of an active antenna should follow
the same installation precautions as for a passive type antenna.
