c) Installation of the antenna
• Unfold the dipole for UKW and click it into position (
• Screw on the whip antenna for LW and use it to fi x the dipole

( ).
• Push the antenna on to the antenna mast head and screw it

into place ( ). Do not fully tighten the wing nuts on the mast
clip for the ARA 10 and ARA 30 initially, since the antennas
have yet to be aligned for best reception. ARA 20 is an omni-
directional antenna and requires no alignment.
• Only for ARA 30: Pull through the elements to the stop,
swing it to 90° and tighten the screws. Insert the square tube
into the head of the antenna and tighten the screws (
d) Cable connection
• Push the black plastic hood up so that the circuit board for
cable connection is accessible.
• Slacken the two strain relief clips a little.
• Strip back the cable insulation, push the cable under the strain
relief clips and connect it. Retighten the strain relief clips.
• Further cables from antennas mounted lower down the mast
can be routed into the mast head.
• Push the black plastic hood back down.
Aligning the antenna
• Rotate the ARA 10 and ARA 30 to the alignment for the
best audio reception. This is done either by listening to the
reception or by using an antenna meter. To do this, select a
program on the radio or meter. For the ARA 30 the director
(the short element) should be aligned to the transmitter.
Precise alignment of the antenna can be achieved only
if an antenna meter is used. Ask your dealer about this.
• Because of its omni-directional characteristics, the ARA 20
requires no alignment.
• Tighten the wing nuts on the locking clamp alternately
by hand and then use a spanner (13 mm AF) to tighten
them one further turn each.
